As a recent purchaser of a relatively little-used 2018 T120, I've been amazed to find that you're one of the most, if not the most, credible sources on youtube for unbiased and helpful information for these bikes. You made this video 5 years ago, but rest assured that it's still providing good and useful information to people today. Just wanted to say thank you and leave this comment on the off chance it helps the channel.

[@melsilva9158]

Stuart, another great video. The storytelling and cinematography is probably one of your best to date. Bravo, sir. Bravo.

[@stuartfillingham]

Thank you very much Mel!

[@malcolmmuirhead8833]

You have described both the problem I had and the result I had with the product perfectly, I fitted one to my 2015 bonneville today, very impressed

[@unixgeek007]

Ordered mine 4 days ago and it’s delivered and installed. My 2018 Triumph Bonneville Speedmaster now rolls smoothly forward with no throttle and slowly letting out the clutch. Going to be great for stop and go traffic. Thanks again for posting this.

[@keithfox4204]

Having bought a 1996 bmw r1100rs 3 years ago,my second.I have been spending time getting all the engine servicework done and overhauling the swingarm bearings and rear drive.The engine on these bikes although having plenty low down grunt,has always been abit lumpy at 3-3500 rpm.After fitting the boosterplug the engine is lovely and smooth all the way through the rev range and idling is also much improved.A very worthwhile modification.

[@grahamlees3199]

extremely glad you did this video I thought it was just me who had these jerky starts and poor low speed control

[@stuartfillingham]

no its not just you Graham although i think some people dont seem to be able to notice it, which i find odd!

[@paulongley2033]

Hi Stuart Great video as always , I fitted a booster plug to my t100 about two months ago and I love the improvement . As you said a must have /fit to your bike . Keep the video coming , information like this is a great help . Paul

[@nigesainsbury9156]

I've been riding with one of these fitted for 6 months now and it is by far the best mod I have done to the bike. It was always a pleasure to ride, but this has moved it up a few notches on the pleasurable ride scale. Great recommendation!

[@hotmaleian]

I agree with Jono below. You sir, are beginning to cost me a fortune but investing in the smile on my face from the pleasure of my riding is worth every penny. I have a 2018 Bonny T100, the baby of the group but this booster plug has made all the difference to slow speed, stop and start riding. Also as a direct consequence of your videos, have fitted an x-pipe from Motone customs, a new Petrol filler Of vintage style and the beautiful Halcon stainless rectangular mirrors recommended from your story of your old motorbike. All items have given me vast pleasure from the D-cat and booster plug providing more power and smooth riding to the vastly improved visibility from the new mirrors. Thank you for fantastic ongoing videos and I certainly beg you to never stop doing these. the Dart fly screen is on the way and your words of caution relating to fitting will ring in my ears. The brass gear change knob serves no purpose other than looking fantastic. Thank you. My wife is very familiar with your name particularly in relation to my desire for British custom sleeper pro silences. All followers of your site are looking forward to your video on feminine persuasion and/or divorce settlement recommendations. I am actually very lucky to have a incredibly supportive wife even though she won't ever ride on a bike.

[@stuartfillingham]

LOL! that is all great to hear Ian! I think your going to love this Fridays video! ill put some thought in to your last suggestions.

[@heiko3048]

Great video. Thank you so much. I’m really exiting about to receive my Boosterplug ;-) Just ordered it and can’t wait to install it.

[@joshmoore6165]

Exactly the perfect video for me to watch, as I try and figure out the benefits of this product. You covered everything sir, and have sold me when so many others have not. Including Booster Plug promotional videos themselves. Thank you!

[@victorfranco7337]

Thank you Stuart. The analogy or is it metaphor of the startled rabbit did it for me, very well put! yes I can relate to that tension of the body. I will buy the booster plug thank you.

[@Ron-ec4pf]

Best upgrade so far! Huge improvement on low speed maneuvers

[@sandygoodall123]

Hello Stuart. Thanks for the review. I recently installed a Booster Plug on my totally stock 2017 T120, and my very positive experience is the same as yours. Great product.

[@stuartfillingham]

yes it is quite astounding isn't it! Thanks for sharing sandy!

[@torqueofthedevil8145]

Just ordered one of these for my Speed twin on the strength of this review, thanks Stuart

[@tinks43]

Looks like another very clever small black box 👍🏻

[@stevemarkarian5553]

Done and done! Thanks Stuart.

[@stuartfillingham]

your welcome steve!

[@paulaustin5970]

Worked very well on my America LT, as you say made throttle response low down smoother and for me engine more tractable especially 2up

[@grahamball364]

Great info placing an order right now ,I’ve only just got my T120 and it does chug about at low speeds ,looking forward to the classic ride made better .

[@christopherpaluck737]

Another exceptional video Stuart!

[@terenceokeeffesmotorcyclestuff]

I fitted a similar device to my 2016 Africa Twin, the Rapid Bike Easy, same simple fitment, same results. Transformed the low speed jerkfest on that bike to a smooth ride, everything else was stock. Sold out for a Triumph Tiger 1200, no such problems at all, they seem to have that well sorted for fueling.

[@unixgeek007]

Thanks for this video. I just purchased this for my 2018 Bonneville Speedmaster. Hopefully this works as reported.

[@billcaveny9495]

I must get one Stuart. Had one on my R1200R and it transformed what was very jerky fueling. Enjoyed the vid’. Many thanks...👍

[@stuartfillingham]

well worth having in my opinion Bill!

[@MrStingraybernard]

this is what i need for my 2017 street cup

[@daveyoude2828]

[@stuartfillingham]

Thanks Dave!

[@jamiebell1528]

Btw, a big fan of your channel in general. And the cinematography at the beginning was awesome.

[@stuartfillingham]

thanks Jamie!

[@josegraziani1164]

I just bought one! I have had the same issue with my T-120 and this is a problem that can really mess with your self confidence and safety, especially when you have your MRS. in the back. Thanks for clearing away another obstacle Stu.

[@kialhansen2703]

Thanks again Stuart. In regards to the snatchy throttle at low speeds, I just flick over to rain mode on the T120, when riding in stop/start situations, makes a Hugh difference.

[@JamesIanGilliam]

i realize this is an old comment, but i must agree. The snatchy throttle is a more of a quirk than a complaint, solved by the rain mode.

[@torqueofthedevil8145]

I fitted one of these to my Speed Twin yesterday and it 100% does everything Stuart says, the bike is so much nicer to ride now. No snatchy throttle, slow speed trailing throttle is easily applied now for low speed turns like roundabouts. Even cruising is better as when you shut the throttle off it’s lost that instant off feeling and feels like there is some tick over still propelling the bike like bikes used to feel. This is the best money I’ve spent on the bike so far. Just a superb bit of kit. Bike fuelling now feels pretty much perfect.

[@robertyoung5910]

Hi Stuart, ordered one and fitted it today and it's just like you described, smoothed out low speed engine speed and is more controlable at low speed and a bit ore punch at mid range acceleration, thanks for the info, that's all I will probably do to the bike and it was worth the expense.

[@sb-hy5ir]

Robert Young - would you say the boosterplug makes the throttle response similar to riding in the rain mode (no loss in power but a much softer throttle response?)

[@DvDrider]

One more thing my Bonnie needs, Thanks Stuart!!!!

[@nizzmo100]

Great video mate .

[@stuartfillingham7011]

Mar Vel thank you Mar!

[@hopgood007]

Hey Stuart, I thought I was in for an unseen episode of "Black Sails"! Great video sir and excellent review as always. I knew there was an answer to that snatchy low speed throttle. Avast and belay sir.

[@stuartfillingham]

Thanks Paul, there certainly is an answer and its name is booster plug!

[@Naessey]

Purchased Booster mod and fitted on weekend. Took all of 3-4 minutes. 1 minute to fit and 3 minutes to ensure cables not in way when seat back on. Will let you know what I think after first ride this week. Hope it works.

[@giovannim5101]

Thank you Stu just ordered one...keep it up love your chanel....👍👍👍👍👍😁

[@hiagftd]

I just fitted a BP to my 2017 Versys 1000, in an attempt to eliminate the snatchy (on/off) throttle. It did not eliminate that, but it did do everything else you described. It took about four hours to install on the Versys, including time to add an extra foot of length to the temperature probe in order to get it to the front of the bike. Man that bike is a pain to work on. One odd thing I've noticed is that the bike seems much smoother at cruising speeds, when the BP is not supposed to be active. Overall I'd say it was money well spent.

[@MrSjeupie]

Just received mine, Stuart. It was the first thing I ordered after getting the keys to my t120 about two weeks ago. The finalised packaging is really nice actually; super quick delivery abroad, simple straight forward info in the box and a couple of goodies with a sense of humour. Installating was a breeze, especially since I already saw your video naturally. Tomorrow I'll take her for a spin and see if the snatchy throttle is improved. I ride a lot of mountain roads here in Switzerland and in the first gear hairpins, especially if the road surface is a bit damaged, the snappy throttly can catch me a bit off guard sometimes resulting me to 'tension-up' and brace myself as you said. If not yet sufficient, a 39T or even 41T rear sprocket (in black!) will be on the way as soon as the original one and/or chain needs replacing. Will report back. For now, thnx for your wonderfull content on the bonnie's. Always interesting, well documented and the video quality keeps going up.

[@MrSjeupie]

Ok, installed them and rode the bike like I normally would. The difference is most certainly noticable. Revs at idle are slightly up but boy is the throttle respons smoother. I always had the idea that it was either 0 throttle or 5% instantly. With the booster plug it seems I can actually get 1, 2, 3, 4, and 5% of throttle too. Much smoother. All other possible differences the boosterplug makes are, in my book, necligible. And that includes the slight increase in fuel consumption. Cause honoustly, a tweet by Trump has a much great effect on my fuel costs than all the booster plugs in the world combined...! Thanks for pointing me (and others) in this direction Stuart!

[@markmasztal2253]

Nice drone footage Stuart.

[@stuartfillingham]

Thank you Mark!

[@tompas11A3n52KkX]

Thanks for the video. I do think that the Booster plug works. The little black box of the Booster plug contains no software, only a resistor that is connected in parallel with the NTC thermistor. The NTC thermistor is a pipe type with fast time response. The value of both the resistor and the NTC may vary depending on the brand of the bike and/or the type of fuel injection used.

[@stuartfillingham]

Ah im sure i read in booster plugs literature that it was controlled by some basic software, but i may stand corrected!

[@harmprins4733]

Hello Stuart, Thanks for information. I have buy also the Boosterplug. I did the test with the plug (250 km.) I can tell you fantastic. The fuel consumption is the same about 1 liter for 25 km on high road with a speed of 120 km/ h. Go on with your tests and advice. Greetings from the Netherlands.

[@andywilliams4920]

I’ve just fitted my booster plug and taken the Bonnie out for a spin. Wow ...what a difference! I can’t understand why some people say it’s a gimmick. Throttle control at stop-start speeds is far smoother, and overall at-speed performance is noticeably stronger. There’s no reason not to get one, especially for riders who carry a pillion and don’t like being headbutted. Thanks for your vid Stuart, it provided the reassurance about the plug I needed to get my wallet out.

[@stuartfillingham]

wow thankyou Andy, I cant believe how many people have gone out and bought one! no one has had a bad word to say about it, (apart from those who dont have one of course) thanks for sharing!

[@johnbrandon9430]

Hi Stuart, I fitted one to my Street twin, what a change to low speed take off, so much better, as you said as if it had carburetors. Excellent bit of kit. Well recommend Stuart well done 👍

[@Kito66j1]

Wow Stu! I’ve been riding my 120 pretty consistently in the last two weeks and yes I have realized that problem myself. I describe it as the bike being confused as to what you want it to do. I also noticed from the first time I rode the bike, how light the throttle is. You can throttle it with just a finger and that plus the sudden jerk of the bike scares me at times. This one is definitely an upgrade worth considering. Keep us updated as to how it continues to perform.

[@stuartfillingham]

i will do Kito, yes ita problem that does make you wary at times!

[@Guedovsky]

Thank you Stuart for another great Video, in my case you are creating demand, I had never heard about Booster Plug and I never knew I needed one... but now... I have to have one :) as I had to have the Union Jack Radiator Cap and The golden Peg gear shiffter :) ... Keep Up the great work. Very nice Cinematographics indeed!

[@stuartfillingham]

Thank you Paulo, you have good taste in accessories sir!

[@michaelreuss4741]

I just installed it on my 2009 T100 EFI (Norman Hyde exhaust, AI removed). I had pretty painful popping and lagging performance. Took me 1 minute to install. Fantastic result, no comparison to before. Definitely recommended and totally worth the money (170 Eur).

[@hotdotdog]

I put a similar device in my 2007 Harley-Davidson. Having a 1548cc air-cooled engine it was really putting out a lot of heat and on a hot day (we get many here in Southern California) I would experience "pre-ignition pinging" and after installing this type of device, I had a cooler running engine with no more pinging and albeit subtle, quicker acceleration. I believe I have extended the life of this air-cooled engine quite a bit as the lean factory setting had this engine running way too hot. I don't yet own a T-120 but it is on the horizon and this will likely be one of the first mods I perform.

[@musingswithmgl]

I swear your always one step ahead of me. Just completed my decat and im still rocking the british customs exhaust tips. People say you cant do both because theirs not enough back pressure, others say its perfectly fine but it'll just run rich, and the perfect solution they say is...dun dun dun....power booster. Ive been researching them for days now and as you say some people claim they are snake oil and some say they are sent from heaven. Glad to have an opinion from someone I trust. Thanks as always.

[@stuartfillingham]

well if it snakes oil sir its damned effective snake oil!

[@yughiii]

Because the booster plug is a one size fits all solution some bikes will benefit more than others, it all depends on how the manufacturer has mapped the ecu. Fooling the ecu into thinking the temperature is colder than in realty is a relative crude way of solving a mapping issue which will work for some but not for others.

[@BoatingBiker]

Re Booster Plug, I fitted mine today ( T-120) in less than five minutes and rode off for a good long ride in the Brecon Beacons. The difference was felt straight away, no snatching, smooth was the word of the day. The power now comes in at 2500 rpm, i can do all i need in 4th. its good, very good. Overall , the T-120 is a very good bike. Thanks Stuart!

[@stuartfillingham]

Excellent Dave! thanks for sharing sir!

[@paulhodgins]

Fantastic bit of kit. I fitted this to my T120 in only 10 minutes. It has transformed the bike at lower speeds and it has made gear changes much smoother. I got mike from Motorworks - they area UK dealer for Booster plug and keep stocks for most bikes and send out really quickly. It works well on its own or with a decat pipe. Well recommended.

[@stuartfillingham]

Thanks for sharing that Paul! nice to hear reports that mirror my own findings. there seem to be a number of nay Sayers around!

[@CyrilHelnwein]

Is your T120 fitted with an x-pipe? Curious if this booster plug is the solution for my decatted T120, which has as a result lost all its back pressure and engine breaking.

[@JasonSobell]

​@@CyrilHelnwein Decat has nothing to do with engine braking. Back pressure from a cat is part of 'scavenging', which is a fueling effect, and has nothing to do with engine braking that's caused by the compression of air with no or little subsequent ignition. Engine braking after a decat is identical to before, so it's a placebo effect. We run a dyno shop, I own a Thruxton 1200R, and we've measured everything related to BPs, PCVs, mufflers, decats etc. Do a Google search and you'll see some of the original results I posted 2 years ago about decat effects on A/F mixtures. BPs will make the bike feel smoother. They over-richen the mixture during acceleration, so the effect feels smooth because it's similar to having a stretchy throttle cable. The disadvantage is fuel economy and performance, as the over-rich mixture reduces torque, but if you prefer the smoother feel then it will do what you want. I would never fit one, as it's like drilling out your pilot jets to add 13% across the range. I'm not a 'hater', I just have a dyno and know what the effects are.

[@CyrilHelnwein]

Thanks @@JasonSobell I was afraid that this is the case. Looks like I need to fork out some more money (€550 to be exact). My throttle is quite smooth as it is, I'm just worried that the now too-lean AFR can cause engine damage with overheating. Was hoping a BP would be enough to solve that, but I guess it is probably not enough and not worth the risk.

[@sb-hy5ir]

@@JasonSobell Jason - does a decat (leaving in stock exhaust) also lower torque/hp? What about a combination of decat + BoosterPlug on a 2019 Triumph T120?

[@spark893]

I think I'm going to buy one now after watching this

[@walttanner5813]

Definitely will be buying this mod in the near future. I hate that jerky feeling at a stop and go situation. Sometimes results in a stall at slow speed.

[@stuartfillingham]

Well worth it Walt! thanks for watching sir!

[@VadersDarkside]

I've had my new Bobber for about 2 weeks now and I NEED to get a boosterplug. I've been riding for about 25years and I've never had so many low speed moments than on this bike. The roads are terrible round my way and just hitting a bump sends me lurching down the road like a new rider 😂 its a fantastic bike but the throttle snatch is killing the riding experience.

[@triumphrider9796]

Interesting description you have for the "blood eagle" (according to one source I ran across, that particular treatment was usually reserved for dealing with the killer of one's father). The Booster Plug seems a rather simple and elegant solution.

[@stuartfillingham]

oh! well we dont worry too much about that around here! the boosterplug is surprisingly effective!

[@nigesainsbury9156]

Just ordered one purely on your recommendation and the reviews from your video. The slow speed snatching is an irritation for sure. Perhaps it will also reduced the amount of clutch wear! Thanks Stuart.

[@richardreusser9327]

I put a predator exhaust and airbox delete on my 2013 SE expecting to budget another 400 for remapping. After watching this I added a booster plug and the bike runs great. Might eventually have it fine tuned, or perhaps just leave well enough alone.

[@robertwuest3462]

There are believers and non-believers all over the web, but I took the plunge and ordered the Booster Plug in response to this video. I installed mine this morning and it completely changed the throttle response from snatchy and unpredictable to almost perfectly linear. This was my first modification to the dream bike that I knew wouldn't suit me 100% straight out of the crate. Next will be progressive rate fork springs. Thanks for the great info and quality videos, Stuart!

[@1shoe]

At high elevation in the mountains on slow curvy roads, my T-120 gives me fits! Jumping and jerking as if running out of fuel above 4,000 ft. Had the computer remapped twice, to no avail. I will be ordering one in about 5 minutes!

[@stuartfillingham]

let me know is that sorts it out Delane!

[@1shoe]

Stuart, that snake oil is amazing! Ordered, installed, rode over 50 miles. I just couldn't get over the improvement of the ride ability of my T-120 Bonnie. Bottom line, it increases the range of each gear. Not the high end, but the bottom range, especially 1 thru 4. I tried my best to make it do the "Herky Jerky", but could not. A winner in my book, thanks for bringing to my attention. Worth every penny of the price.

[@stuartfillingham]

Thank you very much for letting me know Delane. its great to hear other peoples opinions!

[@iainian]

I watched this vid and though if Stuart recommends this product I'll give it a try! I was however a little sceptical that a little black box could make "any" difference? Well, first time out today with it installed, what a difference money well spent! Stuart I salute you, thank you.

[@stuartfillingham]

Thank you for letting me know Iain its always good to get confirmation from others! thanks for watching sir!

[@MrStingraybernard]

Same for me , and once it gets into the jerky motion if you didn’t let off the throttle it would get worse and worse, that’s what I hate about my Bonneville the most , especially going around a roundabouts

[@volt7cooltangs701]

Took my Thruxton 1200 standard out for a quick blast to blast down the 3 lane section A3 in Surrey. Thruxton reached 115mph much easier with Booster Plug. Had a lot to spare too. Was into a head wind as well. Previously I struggled to hit 105mph without Booster Plug. That was a big surprise. Wasn’t expecting any performance gains at the top end at all. Expected the opposite tbh. So seems like 2 lower BHP across the range but better fueling? These emissions rules euro 4 & 5 must really knacker bikes true performance. Low speed fueling seems a lot better but does feel like the “choke” is out 5%. I recommend it. I’m keeping the booster plug in. Now will buy one for my KTM Duke 790 which has really crap low speed fueling around town or roundabouts. Booster plug was an easy install for the Thruxton. Lifted the tank at the seat end via undoing one long bolt, undid a couple of long bolts near the seat/tank area to get access to AIT sensor, simply plug connected the BP to the AIT, then stuffed the BP temperature sensor cable down the close by left side air intake snorkel as recommended by BP. No soldering, clipping or retuning needed.

[@WEEGIMEDIA]

Thanks for this i thought it might be due to fitting the x-pipe and sleeper pros even though i let the fan go through two to three full cycles , in town and at low speed it's terrible really snatchy procuring one forth with .

[@stuartfillingham]

yes x pipe and sleepers do actually help with this problem but they dont dial it out completely!

[@wildhogget69]

Just the video I was waiting for, love the drone shots, I am going to have to up my drone game...👍

[@stuartfillingham]

Thanks Dan, which drone do you have?

[@wildhogget69]

Mavic Pro and I use final cut pro for editing (learned a lot from Ryan Nangle and King Tuts Pro - They perform amazing sorcery with Final cut Pro) I have been scouting an area where there are not too many trees and pylons it's a bit tough with all the mountainous range to get a good follow me active tracking.

[@stuartfillingham]

ah excellent yes my intention was to get the pro but the Mavic air is so tiny its just perfect for carrying on a bike. Im a MVP for cyberlink so i use their power director its an excellent prosumer editing platform. and colour crrection is very easy.

[@chrisbolton2500]

Very timely video for me, Stuart. I fitted a 'Booster Plug' to my Thruxton about three weeks ago. Can't say my bike has ever really suffered from the jerky throttle blight.......but that could be because I'm a savage oaf, with the sensitivity of a door knob, who knows. I have fitted a cross pipe, and V&H silencers. I wondered, primarily, if it would help with the 'popping' in the exhaust on deceleration. It was with that goal in mind I fitted it. Did it eliminate the problem? Did it heckerslike....... BUT, it did seem to reduce it. Other benifits I found? Well, as you mention in your video, it's sort of hard to explain. The bike just feels more responsive, or alive is probably a better way of putting it. The idle on warm up is more strong and steady, and the whole riding experience is just more enjoyable. I know a lot of concern is expressed about increase in fuel consumption, due to the methodology employed by the device. There hasn't been any increase, in fact, mine is slightly better. I put this down in the main, to the fact your getting what you want sooner, and at correspondingly Lower throttle openings. I'm sure there will be other points of view, and people are entitled to hold them. But for what it's worth, mines staying on the bike. By the way, when you buy yours, it comes packed in a really sturdy cardboard box.

[@stuartfillingham]

I shall pin your comment sir!

[@xperiakppxperiaphone2807]

Hello Stuart, just to say, following my first ride with the Booster plug fitted.... Wow!, what a difference it makes. So far so good. No need to tense up or feather the clutch when negotiating mini round abouts. Possibly the best modification so far!? Cheers Keith

[@stuartfillingham]

Great to hear!

[@xperiakppxperiaphone2807]

Hello Stuart, As I contemplate whether or not to PX my 2011 Mag wheel Bonnie for the RE Interceptor, Triumph T100 or Street Twin, I thought I would just give this a go. The deciding factor whether to keep my bike or PX her. A last attempt to make my bike as it really should have been to start with. I love my bike on longer journeys, but, like everyone else it seems, Mini-roundabouts and general slow speed riding can be abit of a nightmare. Just off to the shed to fit the Booster plug, wish me luck. Cheers Keith

[@trevorford2549]

Hi thanks that was very informative about the Booster plug. Can you tell me we’re you got your bar end mirrors.

[@terrierman66]

Following your entertaining and informative film I have fitted Booster Plug to my T120 and taken bike for a long test ride to Reeth in the Yorkshire Dales. Definately noticed a big improvement in slow speed riding with the plug improving low speed throttle response greatly. Took 5 mins to fit as shown in your video and arrived in the same packaging as yours. Thanks for a super informative review. 😊

[@lws2112]

Stuart - are you still rocking the booster plug on your T120? I am seriously considering getting one for my new Speed Twin and wanted to see if you still ride with the BP and what your thoughts are after a year of having it... some forums say its a crude alternative to a powercommander/tune, but I have no interest in spending that money and fitting the PC. I love my Speed Twin but at low speed it just chug along sometimes, especially in Sport Mode. Thanks in advance.

[@scottygdaman]

good stuff thanks. it's occured to me I think the biggest alure of brands like Triumph and Harley Davidson are the performance sound and look of these after caring owners like your self have just about redesigned the darn things. I'm leaning more and more to the Yamaha Tracer gt. Have you had any experience with the Yamaha line? I've always enjoyed their engines . love the channel thx again

[@twinphill900]

Hi Stuart in saying the booster plug sends a signal 20 degree lower. Does it interfere with the opening of the thermostat in the cooling system? Also your video skills, outstanding 👍

[@adrianthrockmorton7557]

Just wanted to say this, I have both a 2016 thruxton R and a 2017 street cup and the street cup is one of the smoothest bikes I’ve ever ridden and is a joy but the thruxton has the most snatchy and jerky throttle response ever at low rpms and I’m hoping this might help.

[@volt7cooltangs701]

I own a Thruxton 2017 1200 Ade and if you think the throttle response is jerky at low speeds you ain’t tried the KTM Duke 790 throttle at less then 30mph. Boy now that really is fkn sh!te. Makes the Thruxton throttle seem as smooth as a baby’s derrière. I’m going to fit Booster plugs on both me bikes. Worth a try.

[@BallsDeep189]

Great video. Id recommend the throttle mod too to take the 'gap' out of the throttle movement. Ducati use the same. I got cheapo off ebay and its great. May I ask what drone you use, amazing cinematography.

[@paulhodgins]

Love the drone footage. Were you near Hollym? I used to fly in there now and again. An interesting place.

I have never understood all the "jerky" starts and inability to regulate the EFI throttle, FZ(MT) 09, FZ(MT)07, NC700X, 1200 THRUXTON, BMW F800R, none of these ever have responded that way nor did my Sprint ST 1050, Bonneville EFI etc.

[@davidwaller2179]

I've not noticed any jerkiness with my 900 Street Scrambler at low speeds, is this a feature of the 1200cc engine bikes more so than the 900cc machines?

[@stuartfillingham]

Its caused by the emissions control system David all modern bikes do it to some extent.

[@bm7760]

Will my 2012 America benefit from this? Pre water cooled model but still jerky off the throttle.

[@flyinggyros9745]

Stuart, is that device available for all bikes? I have a 2012 Honda Interstate vt1300ct. I have the same issues you describe in starting out. It really is a pain in the butt. Thanks, Alan

[@stuartfillingham]

I believe they have a version for most bikes sir, it may be worth checking out their website or contacting square deals!

[@myLostInterest]

Emailed BoosterPlug today with a bunch of tech questions related to the latest Norman Hyde X-Cat and Toga silencer mods to my T120. Received an email reply back from Jens (@boosterplug.com) within 5 minutes. He answered all of my technical questions with a very detailed email reply addressing all of my concerns. Not to mention my follow up email questions; which he answered in the same timely manner. He even emailed me back after my order was placed to let me know that he was available, if needed, for help during the install - NICE!!! ... and, as always, thanks to you Stuart for bringing another innovative product to our attention and also for creating such informative and entertaining vids!

[@stuartfillingham]

Its nice to hear their service is as good as their product! thanks for your comment sir and for sharing your experience!

[@mileshearn]

Was there any concern with fitting the Cat delete and silencer mods with the Booster? Throwing the Motone X-Pipe on the Speedmaster this weekend and now I want a Booster Plug... Thanks!

[@kenweaver5327]

Do you still have the booster plug installed ??

[@chriscoates2399]

With all that said I have an 2019 interceptor I'm fitting headers and booster plug next month Any pre thoughts from you welcome , ? .

[@iivaridark6850]

Well, Peak Biker seems to be rather satisfied with Booster Plug, too.

[@stuartfillingham]

Ah yes!

[@ostekuste3646]

Stuart, after watching this vid I started shopping for one. I’m not sure which will fit my application which is a Street Cup. The supplier in the USA I’m looking at lists a Twin 800-900 series. Is this it? Another spot on review, as I have this issue. Thanks, and by the way, installed the led bulb upgrade exactly as you reviewed and am completely happy. Your tests go a long way towards my final decision about where my hard earned money goes.

[@stuartfillingham]

you might be best giving them a call Chad. to make certain you get the right one! thanks for sharing sir!

Hi Stuart. Wonder if you can shed any light on a challenge I have with the boost plug. I have just changed my T100 for the magnificent and latest 2018 T120 and installed the booster plug after loving its application on my previous bike. Unfortunately the moment it is installed it activates the ECU warning light and after visiting the Triumph dealer they have told me that the latest emission control systems in the bike will pick up items like this and the fault cannot be cleared ( by a triumphant dealer anyway). As a result the warrantee would be invalidated if I ride the bike with the ECU warning light permanently on. Have you come across this problem or has anyone else come across this problem that could possibly share with me a solution. The new bike runs beautifully with the Plug installed but I certainly would not like to ride permanently with the warning light.

[@JasonSobell]

No, that's not why you'll get an error. The BP is simply a thermostat, and it adds a small resistance to the ambient air temp sensor in the airbox. You can do exactly the same thing by fitting a resistor in series with the pink wire to the sensor (but that would only cost 2p instead of 160euro!) :) My guess is that your ECU is not detecting the sensor any longer, either because it's not plugged in properly or faulty. If you hold the 'i' button on your handlebars while you turn on the ignition, keep it held down for about 10 secs, the display will tell you the DTC error code. It may be P0112 (intake temp sensor shorted to ground) or P0113 (air temp sensor open circuit or shorted to 5v). Try disconnecting the BP and plug back into the sensor directly.

I wish it was that easy to fit to a crf1000l

Don't think id dare take this 'scrambler' offroad without something like this haha.

Hi Stuart, has it affected MPG or engine running temperature?

[@stuartfillingham]

Yes Milo it runs cooler and returns 70mpg!

[@larrynorsworthy8582]

I have a 2018 street twin and it seems fine being factory stock. Maybe these were sorted out?

[@stuartfillingham]

No it hasn't but the ST is quite low on power so would not be as noticeable.

[@pepitovfr]

Awesome opening sequence Stuart. Have you invested in a drone ?

[@stuartfillingham]

Thank you sir, yes I have!

[@BobC777]

Trumpy - I had the exact same question so thanks for asking !!

[@hammersteve8]

Stuart, do you still ride with this fitted. If so, have you noticed any change? I ask as I see from some forums that some are of the opinion that the ECU has eventually overridden the change that the booster plug makes, thereby rendering it useless. Cheers

[@stuartfillingham]

stay away from forums. they are full of idiots!

[@ronhirsch1944]

Have you got something against Tyr? Seriously, your clear explanation sent me off to their website to buy a couple. Unfortunately, Euro 5 makes it unviable for my 2021 RE Continental GT 650 and fitting one to my 2020 Goldwing DCT would involve dismantling tons of plastic (No, I haven't won the lottery, I just decided my money would rather roll around on twisty roads, or any roads for that matter, with me on its back than hang around in the bank waiting for my heirs.). Kudos to them for being clear and honest and to you likewise. Good riding.

[@stuartfillingham]

Tyr?

[@ronhirsch1944]

@@stuartfillingham Norse God of war after whom Tuesday is named. The only one brave enough to meet Fenrir's condition that someone put his hand in his mouth before he would allow himself to be bound again. Subsequently known as Tyr the keep left handed, which ruled him out of being a biker. N. B. It was his right hand which became wolf food so even a bike with an automatic gearbox would be no good. Many thanks for the like.
