bring on the videos yo, the more you make the more people are getting interested keep up the good work... just bought my first 2015 ruckus and I'm going to enjoy building it with you guys

[@Ethan.s..]

Re-jetted today. With the help of my JIS screwdrivers I got the screws all out with ease. I have a UNI stage two style intake and a two brothers black series carbon fiber exhaust. Went with 38/85 jets and no shim. It runs really good, no bogging any where, smooth acceleration. Thanks for the help with this vid Bobby.

[@AndrewSmith-eq8np]

If the float bowl screws have a center pop. Mark on the head they are not Philips head screws they are jis (Japanese industry standard) screws which have a slightly different taper on the screw driver head

[@Midnightrayne333]

I appreciate this video so much! I was able to do this and its working great! Thank you!

[@vkhiev]

Thanks for the clear detailed guide

[@aland1618]

Wow I'm glad I watched this. Not because of the jet replacement but because I learned about the heated carb fittings. I did not know the carb has a cold weather heater. Maybe that's why when I tried running the scooter just before winter the carb was slow responding even after 5 minutes of warm up. It was below 32 deg F for about two week. I probably should have let it warm up about 10 minutes to get the coolant hot so it could the carb could warm up too. Good to know.

[@thedancingsousa]

What if i do lose that small spring while shimming the needle?

[@Rosa90081]

Lost the 3 screws for the Phillips #2 ....what is the size??

[@derekcurtis818]

Awesome video! This is 💯 new to me lol. I’m about to pull the trigger on a white and red 2015 ruckus that’s stock. Never ridden one yet but I’m excited. It has a little over 2000 miles on it. I’d like to get a tad more hp for acceleration and a few mph here and there. Mains here are 35 unless I go out towards Walmart which is 45

[@ronmendoza4916]

Derek Curtis I got a Yoshimura exhaust and a stock replacement K&N air filter for my 2007. I left the re-jetting to my local Honda Motorcycle Dealer. They did an AWESOME job. I got more acceleration and speed.

[@Bannerape]

I bent the needle, any idea where I can get a new. Honda dealer wants to sell me a whole new carb

[@dudeguyinc]

I see you removed the brass disk and filled the hole with RTV. What is that hole for and what's the advantage of filling it with RTV?

[@nicholasventura4107]

By putting the new jet Can I remove the stock air filter

[@Denman500.]

Good video.

[@ericparisien3051]

The video is informative on how to change the jets and add the shim washer, however, I am left to wonder on the advantages I would have to change my stock 75-35 to 85-38 and to shim it? Thanks.

[@Theruckshop]

you would only do this if you get an aftermarket exhaust and an Airbox delete kit. it would run bad if those 2 things were not changed.

[@ericparisien3051]

thanks for the quick reply, that is what I shall do!

[@lillysings17]

The Ruck Shop what will happen if you have aftermarket exhaust and airbox delete with the stock jets ?

[@josephfoster3819]

I re jetted my carb and now it bogs down at about 30 and don't get above 35mph unless I barely give it throttle . The jets didn't come with a shim ?

[@michaelflameborne7624]

1) What is "bogging"? 2) When you say "number 6 socket" do you mean a 6mm socket?

[@chrisl.7345]

Cutting off 2 rounds of the spring will help too…☝🏻

[@keithbennett1359]

I have a quick question , does the float needle port have a brass or similar seat or does the needle seat directly in the aluminum hole , Any ATV carbs I do have a brass seat. I was wondering if the seat may have gotten lost during cleaning ???

[@yingyang0122]

Question: I have a TRS Hot Lap exhaust system on my 49cc, if I take off the silencer do I need to rejet? I took it off and rode it for a few minutes then it wouldnt start anymore but after I put it back on it started right up after a few tries

[@ryanvojtech2410]

you guys should put together a video explaining how to stretch a ruckus plus mounting a fatty rear wheel... please please please

[@jacobschwerke7367]

Where can i get this shim ??

[@fisher5413]

Got your full intake kit with jets and shim. Followed all the steps. Crazy thing was when I removed the top diaphragm cover, there was not a longer spring. Just the small spring connected to the white needle retainer. So I added one from an old carb that came with extra parts when I bough my 2014 Ruck. It would not start. I removed the long spring and it started right up. I'm puzzled as to why???

[@Ethan.s..]

It my be Honda revised that aspect of the carb. I have read the shim is needed more for the older pre 2006 or pre 2012 Ruckus’s. Not 💯 sure about this information though.

[@originalgreek]

Great video! Should I go ahead and put the shaman? What’s the chance I’m going to need it? Does it hurt if I put it in anyway?

[@Theruckshop]

it makes it richer on the mid throttle

[@Kbails84]

How can I tell that a proper Air/Fuel ratio has been met after I upgrade the air intake, exhaust or variater? If I do this and use an 85 jet for example, how will I know that an 80 or 82 wont work more efficiently?

[@Theruckshop]

the variator will not have to do with your jetting but the best way to tell is to go wide open then while keeping the throttle wide open use your other hand and cut the ignition off then pull over and check the plug. by doing this you will know exactly how your mixture is at the point of cutting the throttle off. if you were to go full throttle and then slow down and pull over then cut the ignition off it wouldnt read as accurate. thank you

[@Kbails84]

That is awesome advice. Should I begin then with a new spark plug if I make these changes? Thanks for your input.

[@joshcarlson2265]

when assembling the clutch back together should i put lube on any of the parts?

[@Theruckshop]

its not needed no.

[@SDsailor7]

@@Theruckshop The idle jet on my ruckus is clogged big time, i tried to use the jet cleaning wire tool and it is not going thru it feels like there is cement there. Should i just buy new jets? Also can i get them at any honda motorcycle dealer? Or where can i get them. My other question is, why replace with a different jet number vice the original? Excellent video! Thank you

[@jrojas07]

thank ya'll

[@Bigtexas65]

I can't find the kit your talking about in the video at 2:45 where you said "Air box kit, 1 or 2" Id like to order the two jets and the shim from you. Please let me know. Thanks for your video.

[@Theruckshop]

they come with the airbox kit when you buy it from us. if you did not then you have to order the jets separate on the site or order the complete jet kit for 49cc on our site

[@HectorR906]

Once this is done how do we tune the carb?

[@Theruckshop]

HectorR906 that is tuning the carb

[@HectorR906]

The Ruck Shop so we don't have to do anything with the idle screw or the air fuel mixture screw?

[@Theruckshop]

HectorR906 idle you may have to adjust after the scooter is warmed up. For the a/f screw leave it alone . It's set pretty good

[@Theruckshop]

HectorR906 also I would not put in the shim at first and see how it rides the shim if for mid throttle bogging if it needs more fuel most people do not need this shim

[@melvinflint9714]

The Ruck Shop my ruck starts right up and goes for about 15 min then in middle of throttle it like stalls out doesn't turn off just won't go I have to shut it off cpl min then starts right back and goes another 7 min and same thing happens any ideas? Thx

[@SDsailor7]

Why replace the jet with a 85 and not the original 75? Anyone know? Thank you

[@Ethan.s..]

If you add a aftermarket intake and or a performance exhaust. More air going through the air pump means the more fuel you’ll need.

[@BugKillerMetal]

Im into my second aftermarket exhaust and im told to rejet again. The first time i jetted was when i got your guy's performance upgrade. If i need to rejet again which sizes should i buy?

[@Theruckshop]

does the bike not run good? usually you dont have to re jet unless its running poor. if it is id get a jet kit and play around with the main jets to find the right combo.

[@eyeswideopen8115]

What's going on fellas , I brought two 2017 Rukus's & the fuel filters clog easy if not driven within a week or so , even with tog grain gas & fuel stabilizer . I need tips on a better filter & also any easy mods to make them faster then 40 mph

[@KingOstrichGamer]

real talk buy a bike with a bigger engine

[@Bdenn570]

Stfu

[@chicagosbackbone]

So when I re-jetted my carb for an airbox delete and exhaust install I didn't shim the needle. It doesn't idle now. would it be safe to say that's due to not shimming the needle?

[@Theruckshop]

only the TVR needs the shim . adjust the idle screw you alway have to do that

[@chicagosbackbone]

The Ruck Shop okay thanks

[@lockpickman5504]

Did the airbox delete and used the 38/85 jets and ran perfect. Then added the Yoshi TRC exhaust and now I lost 10mph and I'm slow to accelerate at all speeds and get lots of popping. I want to know if I'm too rich or lean before I buy the jetting kit from you guys. Any advice?

[@Tor2Guh-]

Popping is running lean. Also, check the spark plug. If it’s white, it’s lean. If it’s soaked, it’s rich. It ain’t white, you’re good. If it ain’t soaked, you’re gooder. That’s how it was explained to me about 4 years ago.

[@joshcarlson2265]

I recently put a new variater / clutch torque spring, and belt, I also changed the air filter to a k&n would you recommend the 85/38 jet setup for that, the issue is when I Rev the engine I'll start going 10 but that it seems to be maxed out on rpms?

[@Theruckshop]

please give us a call 8133554828

[@fidpiano]

Josh Carlson just saw your post. I have a 2017 ruckus. Did you get it working well. Any suggestions/. I am just starting to modify my scooter. Did you. Install a. Tachometer? If so. Any suggestions?

[@InsidetheCasino]

That "diaphragm" is actually called a vacuum piston.

[@EbolaSquirrel]

its more of visual aid,not vocab

[@avchihunzza50]

can you put 110 jets into 49cc carb

[@Theruckshop]

i wouldnt do it since there is no reason to go over 85 with the main jet. i have seen in very few circumstances that a customer went to 88 main jet but generally you will never go over 85 it will be too rich and fall on its face.

[@Frameshaft]

I got the version with the UNI filter, is it normal for the intake to be loud as (almost) hell ? Also, was going fine but then after 10km or so engine stalled and wouldn’t restart. After cooling 15 min starts and idles but as soon as I turn throttle it dies. Any thoughts? Stock exhaust.

[@Theruckshop]

if you have stock exhaust then you only put the 85 main jet in and not the shim or the idle jet. leave the factory idle jet in. but yes it will be louder.. you are too rich right now so thats why its acting like it is.

[@rommelpapa2873]

hi guys, where can I buy the shim you put on the needle? I ordered a set of jets from ruck shop but didn't come with the shim. I installed the 80 jet. now when I rev the the gas, the engine dies. I think I need to shim the needle as you showed.

[@Theruckshop]

that's not your problem, you need to email us , what exhaust you have, and what intake etc.

[@rtube378]

everything is all stock with my 2004 49c Ruckus.

[@ivanstudio7414]

So if I removed the stock air intake, got a Yoshimura exhaust and killed the rev limiter w a CDI, what jets size do I need? Bike doesn't run properly, I think too lean or rich... Thanks in advance!

[@Ethan.s..]

Depends on the intake you’re running and if your at a high altitude or not. People have success with 38-78 through 38-85.

[@sappysport215]

So let me get this straight, shim is ONLY good for midrange power correct? (Btw I bought your intake v2 kit) I haven't put in the shim yet, I've only put in the 38/85 jets without the shims first to see how it runs, it defiantly have me a lot more top end and an increase of 3mph hehe (but I'm getting an air popping noise tho)

[@Theruckshop]

sappysport215 correct . Most do not need shim

[@sappysport215]

The Ruck Shop well I live in philly at sea level n it's 35-40 degree now lol it feels n sounds like I need to jet up higher to a 88 main jet. I'm still getting the deep tone sound n air popping noise and also high idle coming to a stop. What are your thoughts?

[@Theruckshop]

please email us at [e-mail] so we can help more. We need to know what exhaust you have well. please email your answer

[@sappysport215]

The Ruck Shop ok

[@sappysport215]

Or buy imperial size Philips

[@louistopper5679]

is this the same on a zoomer?

[@markusoja2961]

zoomer is fuel injected, it doesn't have a carb

[@Ethan.s..]

@@markusoja2961 2008 and newer zoomers are fuel injected. Pre 2008 (2001-2007) run a carburetor.

[@joshcarlson2265]

just changed the stock variater to a polini using 5 gram weights, polini kevlar belt, and I used the white polini clutch spring, I replace the clutch shoes and springs with OEM parts from honda, I also added a drop in k&n air filter to the stock box as well, I was able to see a big acceleration difference but I feel like my top speed is about 30 to 35... should I just re-jet the carb as in this video ? also after a good ride or while chillin at a red light the bike will die while idiling, will this help fix that issue?

[@Theruckshop]

please send us email at [e-mail] i would take off the white contra spring and put stock back on. are you running an exhaust. Anytime you give the carb more air you need to rejet. email us your response

[@KJ-xn7yc]

Hey quick question. I have a yoshimura exhaust on my 2017 Ruckus. It seems to run perfectly, would it still be beneficial to rejet and run 38,85 jets rather then stock?

[@Theruckshop]

yes i would still re jet the carb, do you still have stock airbox?

[@KJ-xn7yc]

The Ruck Shop I actually just ordered the air box delete kit from you guys so I will be rejetting it! Thank u

[@ryanvojtech2410]

sorry what I meant was attach a wheel with hub to the rear swingarm video.

[@aland1618]

The hard part is removing the carburetor from the scooter. (Car bure ator?? or Car ber ater?? Or Car bur e tor?? HMMM)

[@SurfingTacoMedia]

Not rocket science!? I beg to differ! Just kidding, but pulling the carb out is not very easy when you have to remember where all the tubes go. Doable though.

[@aland1618]

Bad advice on gasoline disposal from the float bowl. One should attempt to capture the gas and reusing it so as not to allow the vapors to contaminate the environment.

[@Theruckshop]

Alan D1 are you kidding us ? I hope you drive an electric car , your car pollutes the environment more than these vapors , every time you fill up your tank vapors come out of the hose . You seriously have too time plus your float bowl usually has trash and sediment in it and you would be putting that back into your tank . Comments like these are just to comment. We apologize we didn’t tell customers to take the gas out from the float bowl and strain it under a enclosed container with rubber gloves since gas also is known to cause cancer too 🙄. Next time we do a video we will just not do one since we didn’t cover all the parts to protect the environment and we will let the customers know that Alan D1 doesn’t want us giving bad advice

[@aland1618]

@@Theruckshop Wow! disappointing. It may only be a drop in the bucket but a thousand drops fills the bucket. A simple comment about environmental conservation is all it takes.

[@ednorton1853]

Come on man. If you're going to do a video like this then do it right. Telling them its ok to let the gas drain out all over the bike and it will evaporate? Yes it will and while its doing that the ethanol is doing nasty shit to anything it is laying on while waiting to dry up. How about Take 10 inches of 6mm vacuum hose and slip it on the drain tube that is staring you right in the face while your saying that and let it drain off into a catch can or cup what ever. Next,.. vise grips? ok but show them how to use them the right way. Im guessing you dont know. You were never taught ? If someone has a float bowl screw really in there like I know they can be. ? They wont get it out the way you showed them how to do it. I'll let you figure it out for yourself. I will tell you this. You use the vise grips, and channel locks the same way. And they only work one way. They wont the other. Think pipe wrench.............I say that because its important. They go to try it and if you dont make it a point to show exactly how they will not know. and will not get it done. If they use them the right way they are very effective. The wrong way and they are useless.
