Powerspark Ignition + Motorized Bike on Dyno | 2 Stroke Tuning

[@jbsnelling1]

Just installed one of these on my bike on Monday and can't wait for more videos on this project. My brother & i have done extensive work to mine but haven't been able to run it yet.

[@2STROKESTUFFING]

+Janella Snelling Cool, thanks!

[@randallvanpernis3614]

Man id love it if you could make a flywheel/TCI conversion kit. I'd Buy it in a heart beat.

[@sumdude4]

Nice to see someone putting these mods to the test with real numbers instead of just feel of it. Good work!

[@2STROKESTUFFING]

+Colin B Thanks!

[@thefunniestfarm4731]

How dare you question the butt dyno??? Kidding, glad someone is showing us dyno charts on their mods.

[@Trumplican]

its so cool you can hear the difference! cant wait to see the exhaust, awesome work bro.

[@2STROKESTUFFING]

+Dragon800 It is! Thanks!

[@MagirusLP]

I love this series, so interesting to see what each modification does. Thanks for your effort!

[@2STROKESTUFFING]

+DerMagirus Agree! Thanks!

[@xibidit]

how happy i was when you said next time we will try a proper pipe :) nice video man this is really interesting! keep it up :)

[@2STROKESTUFFING]

+Kristoffer Persson Thanks! Yeah it's time!

[@BuildBreakFix]

This guy is like super awesome! Only person every to get dirty and show his work with a reason why and such in real time. I used many of his videos to rebuild my 1/5 scale trace racer rcs

[@PiazzaWoodWorks]

Merry Christmas brother love your work

[@2STROKESTUFFING]

+Chris Piazza Thanks, Merry Christmas!

[@RaulMendez-nb4cr]

How What

[@monoracer_]

Cant wait to see the huge power gain of next episode with a expansion pipe! A part that is seriously underestimated by allot motorized bikers

[@davespooney8472]

Great vid! Good to see how timing changes affect the engine. Happy new year!

[@2STROKESTUFFING]

+Dave Spooney Thanks, happy new year!

[@teal80]

HOW?!?! Your motor sounds perfect

[@Mads_Villebro]

This is so brilliantly nerdy... love it! Merry Christmas and a happy new year, greetings from Denmark.

[@2STROKESTUFFING]

+Mads Villebro Thanks😂 Merry Christmas!

[@DaleMcKenna]

I think you are seeing even more gains than just tweaking the magnet with the stock system since the stock CDI is not very strong. Good stuff! Cant wait to see your results when you build a pipe.

[@2STROKESTUFFING]

+Dale McKenna Might be!

[@jjhack3r]

excellent job. I never touched my ignition system besides the one time I got water inside and had to replace the magneto. now i'm thinking I probably should mess around with it.

[@2STROKESTUFFING]

+jjhack3r Thanks! Yep, good idea!

[@BK-it6wg]

you probably know this but the more you advance your ignition timing, the more heat the engine is going to produce, so be sure that youre jetting is sorted so you wont seize...

[@TurbineResearch]

These bike motors are fun to play with. I noticed a big increase in top speed (power) when I modified the piston skirt on the intake . Also running on ethanol seemed to improve performance. It's cool you have a dyno to check the performance after modifications. Cheers

[@robertsironen1243]

I heard ethanol is bad for 2 strokes, it doesnt mix with the oil or something

[@TurbineResearch]

@@robertsironen1243 alcohol based fuels are corrosive and can cause problems in carburators if not stored and cleaned properly

[@nicgyver8359]

Very awesome. thanks again for all the work and effort you put in to helping us understand how some of these things work and effect end performance.

[@2STROKESTUFFING]

+NicGyver Thanks! It's all fun!

[@pascalfiocconi]

Short video with top content. Keep it up, it's a pleasure to watch and learn. Thank you !

[@2STROKESTUFFING]

+Pascal FIOCCONI Thank you!

[@Phil2stroke]

Love it man keep it up !

[@2STROKESTUFFING]

+Phil2stroke 👍 Thanks!

[@LL-se1vj]

Great work this step for step dyno testing and adjusting mods 👍👌

[@colta51]

Sounds way better with that ignition!

[@2STROKESTUFFING]

+Sean Fiba Yes!

[@Marc83Aus]

Great work, 80% more power already.

[@2STROKESTUFFING]

Thanks!

[@CJE2007.5]

Merry Christmas to you as well. Dang near 1 hp gain that's pretty cool.

[@2STROKESTUFFING]

+Chris Edge Thanks!

[@daVidFonda]

Happy New Year. 2019 ;) Great vids, you rock !

[@2STROKESTUFFING]

Thanks, happy new year!

[@cycle47hall20]

With no reeds, a port sys needs a boost bottle, amazing difference , report back results.

[@jdmjedi777]

Great stuff as usual! I always learn something new watching your videos.

[@2STROKESTUFFING]

+jdmjedi777 Thanks! That's great!

[@Westhelockpicker]

Wow I didn't think advanceing the timing would make that much of a difference. I'll have to try it on my zeda 80. I already have every performance part they make

[@derknobit2616]

Great video!!! motivation to get back on my bike project. Had to do head gaskets on my daily driver 100 ft/lb one handed 16 times is painfull

[@2STROKESTUFFING]

+derk nobit Thanks! Working on cars is a pain!

[@jonathancardozo]

Happy New Year my friend, here from Brazil, your work is amazing.

[@2STROKESTUFFING]

+Jonathan Cardozo Thanks, happy new year!

[@JamesD1776-uc]

Merry Christmas brother! Great information & video!!!

Thanks!

[@gwo7610]

As always, top quality content!

[@2STROKESTUFFING]

+Guy Osgerby Thanks!

[@smokey90]

great video! it is been long anticipated.

[@2STROKESTUFFING]

+smokey90 Thanks!

[@kugitv4320]

I love this Videos of the motorized bike, i'm so happy when i see there is a new video of this thing🔝 and an idea is, that you make the flywheel lighter by drilling holes

[@2STROKESTUFFING]

+Kugi TV Thanks! Could do that, but it's already pretty light(aluminum), and preferably I'd want more inertia to dampen vibration.

[@jonnyrox116]

Merry Christmas to you my good man. I look forward to seeing all the mods you plan for that Chinese bicycle motor. Thanks

[@2STROKESTUFFING]

+Jon Rothenbusch Thanks man!

[@collectivepitch8656]

Happy new year man thanks for all you shared great job💯 helpfully

2STROKE STUFFING Tanx

[@jayvlog9841]

Great job

[@blackbirdxx928]

Like i always say, factory ignition timing numbers are always conservative and if you have the skills to test there are always some free horsepower to be found. My silly little 165 hp honda....the ignition is locked unless you spend a hundred dollars on a +4* degree reluctor wheel...the +4* was good for .2 tenths of a second from 0-70 mph...i elongated to holes for the pickup for +2* more and that was good for another .10...and...its an 11.5-1 motor that still runs best on 89 octane.

[@fiftynineridge]

Great video as usual :) do you use the CE-i 100 (11-14V) or the RC-i 100 (4-12V) ignition?

[@2STROKESTUFFING]

+JJ's Garage Thanks! It's the CE-i.

[@mikem5475]

VERY GREAT VIDEO, thank you so much

[@2STROKESTUFFING]

+IamTROLLIFIC Thanks!

[@DrNevaMrMind]

Dam bro every impressive video and what you are doin here I just built. My first chopper build and really like your video here do you have more on makin them run better mine seems. To not sound like yours at all and boggs out alot I know nothing about engines and most people videos are not very detailed like what you got goin on much respect

[@thatbuelldude189]

Hey man would love to see you one day build up a Cr500 or cr80 to see what you can build them up to Great work as always brother

[@2STROKESTUFFING]

+Ford For Life Thanks! Might happen!

[@thatbuelldude189]

2STROKE STUFFING would be cool to see, if cr500s even exist over there lol

[@blainemacdonald6929]

You will need a heavier roller!! I'm building a cr500 shooting for a reliable 80hp love these videos

[@edboer2851]

Happy new year MacGyver

[@2STROKESTUFFING]

+Ed Boer Thanks, happy new year!

[@theslowlaneadventures9029]

Nice work

[@2STROKESTUFFING]

+The slow lane adventures Thanks!

[@AuMechanic]

Good its going again, were you able to do any comparison to see what effect more intake timing had.

[@2STROKESTUFFING]

+AuMechanic Not really as I don't know what stock ignition timing was...

[@AuMechanic]

Yes that makes it hard. Maybe try another run with the muffler end cap off to compare like last time to see if it has the same effect, and maybe a run with the outlet pipe closed off very slightly as well as this run to compare.. It will tell you fairly quickly if the engine will gain much benefit from a tuned expansion chamber. If there is some noticeable diff in adjustments to the outlet pipe then you can expect to get something from a tuned expansion chamber. If not then its possibly a bit lame in the BMEP department and might need some port mods. More back pressure creates more port plugging effect even without a baffle cone and over a wider range. If you remove it totally then intake spilling should occur at exhaust port and power drop a lot and closing it up some boost in power at least somewhere in the range if not top end, if there is not much effect then a new tuned chamber doesn't have as much to work with. A mild pipe might give you more lower down under those conditions but I would not expect much top end boost if the engine is not up to par on the gas side.

[@2STROKESTUFFING]

+AuMechanic Sounds like a plan for the next video! Thanks!

[@2STROKESTUFFING]

With the extremely limited blowdown I suspect it needs all the help it can get getting rid of spent gasses.

[@AuMechanic]

Yeah i just looked back at the other vid at the 140 Ex and 120 Tr. That ex timing might need a tweak too.

[@johnd.5601]

39% increase in HP is impressive. That's the equivalent of adding a supercharger to a v8 engine and going from 300hp to just over 400hp.

[@bikebuilder7883]

Can you show the torque numbers too?

[@2STROKESTUFFING]

+Bike Builder I'll have to hook up the rpm sensor, I'll do that for the next run.

[@sheldonhawkins7256]

U should get a mx65 pipe or make a good expansion chamber im sure you would double hp or more you already ported id say pipe next love your videos man

[@2STROKESTUFFING]

+Jonny Doe Thanks! Pipe next!

[@javiertorres5306]

You the MAN.😎

[@2STROKESTUFFING]

Thanks!

[@mustafaYkhan]

That's a big ass grinder...

[@blackbirdxx928]

X2 on that...dude should be happy he could get a carb in the first place....hey, maybe he is building a 100 point restoration.

[@thegeokiller1529]

Just got one of these

[@nightmareinaction629]

I wish I could keep up with your videos but I saw you made a specific video about that tci I'll take a look

[@s.knudsen3852]

God jul og godt nytår her fra Danmark. Og det er så Nice et projekt ;-) blive spændende med ordentlig potte på

[@2STROKESTUFFING]

+søren Knudsen God Jul og godt nyttår!

[@superkas]

You are my man!

[@2STROKESTUFFING]

+Surya Perkasa Thanks!

[@dannyoutlaw9919]

Oh yeah I just subscribe to your channel thanks again brother

[@TilmanBaumann]

Looks like it ran a little rough and weak with the 20° timing in low rpm. Perhaps only advance so much in higher rpm. I'm sure the ignition can do more than flat map?

[@2STROKESTUFFING]

+Tilman Baumann yes it can, did flat line for simplicity.

[@2STROKESTUFFING]

+TheFunniestFarm I will, just keeping it simple with a flat line for now.

[@brianlofton1430]

Most engines like 28-34* total timing, with a static timing of 6-14*. Since its fixed you should set it for total timing. Give it more timing!!! Great videos!!

[@2STROKESTUFFING]

Thanks!

[@WICKEDGIXXERL]

Do a nos build .

[@2STROKESTUFFING]

+racing squid 186 Would be fun!

[@TheProspectormike]

With all them tools and know how why are you still using a chain tensioner no matter how good the chain tensioner works they make for a bad ride .. Build something that allows you to move motor and tighten the chain that way and you will see huge change in smoothness ... Just look at your chain in your video it don't look like its to bouncy but even that small amount is allot bad vibes... And another tip is to put a ubolt to clamp your muffler to the frame as tight as you can and don't use any rubber damping stuff you want that motor solid to the frame no play at all makes night and day diff

[@Formula400Pontiac]

Im having issues with fouling spark plugs NGK on my modified Suzuki ts50er. To the point that it's a struggle to get the carburettor fine tuned. Soaks the plug 2-3 times before i get it running stable. Its a no reed valve cylinder kit on the bike so that's probably not making it easier in regard of tuning the low end of the carb. The Powerspark Ignition sure would make tuning easier but what do you recommend for spark plugs. There must be spark plugs out there more forgiving in regards to rich mixture setup on cold start. Lagavulin. Great stuff!

[@2STROKESTUFFING]

Lagavulin sure is tasty! Have you tried a fine wire electrode plug like BR10EG? Could help, not sure they're available in short reach.

[@shug831]

Love it. Good to see it coming together but what revs was the power peak and what are you drinking? Reminds me of a Malt whisky bottle.

[@2STROKESTUFFING]

+Hugh Cameron Thanks! Peak at about 6k. Lagavulin 16yrs

[@shug831]

2STROKE STUFFING thought it was Lagavulin, one of the peatiest whisky you can get. Try Laphroaig if you like that strength of taste but it must be expensive where you are!

[@2STROKESTUFFING]

+Hugh Cameron Love Laphroaig, and yes, expensive.

[@kareyriggs1018]

Get a lathe and a mill dude!

[@dannyoutlaw9919]

Hey brother thanks for the video I'm just getting into these little motor iv been building one and I've been trying to find a way to advance the timing...are going to start selling the ignition module that you made??

[@capchassuck]

wouldn't it be great if the engine has a heavyweight flywheel? I'm sure you have seen the centrifugal clutch adapter and side cover but rather then use the clutch instead somehow attached a heavy flywheel where the centrifugal clutch would be! love to see if you would actually try this!

[@2STROKESTUFFING]

+Daniel DeNapoli Interesting idea, and yes it could probably benefit from a heavier flywheel.

[@capchassuck]

2STROKE STUFFING I can imagine it would enhance low end torque or boost momentum for start off during manual clutch engagement . thanks for the input. I subscribed to you're video's to see what's new for the bicycle mount engine.

[@overr8ted2]

Awesome I’ve been hanging out for another vid do you think there is much to be gained for changing the carb at all? I can’t imagine the cheap Chinese ones are that good

[@2STROKESTUFFING]

+overr8ted2 Should be with a larger one, but the intake needs work first.

[@jeofbergamin4130]

overr8ted2 there has to be as I have one and they are shit!intake manifold has all those kinks and not matched to port and carb has no pilot or idle.40’s tech.and the air filter on these bike engine kits is so bad,you might as well tip dirt down the carb yourself!i wouldn’t mind trying a 19mm mikuni.

[@overr8ted2]

Yea they are pretty rubbish I’d like to see a nice bell mouth trumpet on the end of the carb too straighten up the air flow and get it working more efficiently

[@marcusmcclelland]

Why does it hollow out in the middle at 25deg? deto? your videos are great keep it up!

[@2STROKESTUFFING]

+marcus mcc Could be, or just a hiccup. Thanks!

[@snackbar5022]

Great video as always :) What's your favourite liquor by the way?

[@2STROKESTUFFING]

+Snackbar Thanks! Favorite is Rum(Mount Gay Extra Old in particular) when I want something different I go with Peaty whiskeys.

[@snackbar5022]

2STROKE STUFFING thanks for the answer! :)

[@dzintarinch]

Instant subscribe

[@2STROKESTUFFING]

Thanks!

[@MetalMaster8888]

And what is the stock spark advance? 25 degree of advance seems too much for me. If the main jet still .75 than the mix is too rich, maybe that's the reason of high advance spark effect.

[@2STROKESTUFFING]

+Alex Ray Sounds plausible! Not sure what stock advance was.

[@muhammadsyafiq7760]

just curious, will u throw a turbo anytime soon

[@2STROKESTUFFING]

+Muhammad Syafiq Not anytime soon, sorry. But eventually, yes!

[@muhammadsyafiq7760]

2STROKE STUFFING Awesome! That's the answer I want. Looking forward to see the video mate. Cheers. Really good making a subscriber enjoy the channel, at least for me tho.

[@2STROKESTUFFING]

+Muhammad Syafiq Thanks!

[@borcemitev2903]

any similar ignition but with power for lights/battery charge?

This is wkd cool bro

[@stanpol1921]

Why do you cut the piston skirt? What does it do?

[@2STROKESTUFFING]

Increased intake duration.

[@oldtrip1765]

change the plug wire for 7mm braided magneto wire and a zero resistance ngk boot

[@pascalfiocconi]

where is the link to the progammable ignition system you use ?

[@2STROKESTUFFING]

+Pascal FIOCCONI Oops, forgot it... It's in the description now. www.power-spark.de/index_en.html

[@matejhujo5198]

Good job ! 👍 it was Nice to see how horsepower increase after removing exhaust cap. Whats Your plans for silvester ?

[@2STROKESTUFFING]

+Matej Hujo Thanks! What's silvester?

[@matejhujo5198]

2STROKE STUFFING Haha the Night btw. 31.12 to 1.1. 🤟🤟🤟

[@nightmareinaction629]

Wowoowow say that again tci ignigtion I'm having problems with that in my fzr1000 1989 motorcycle I just wanna bypass everything else to make it turn on so there is spark any tips I have a problem with the electrical the wont turn on the cdi I think one wire to the relays is bad but yeah

[@jackfairey1099]

Nice👍

[@2STROKESTUFFING]

+Jack Fairey Thanks!

[@janhendrikfranke]

What about a good carb?

[@2STROKESTUFFING]

+Jan Hendrik Franke Coming.

[@almostsapien]

Will riding without the exhaust cap damage the engine?

[@emilgallardo4287]

So nice tnx

[@Trumplican]

are you worried at all with the flywheel if its balanced properly do you think it will have a negative effect on the crank bearings?

[@2STROKESTUFFING]

+Dragon800 Nope. Any small unbalance in the flywheel is negligible compared to the massive unbalanced forces from the reciprocating mass.

[@Trumplican]

thats a good point

[@2STROKESTUFFING]

+Dragon800 I should maybe be worried about that 8mm chineseium axle tho...

[@Trumplican]

agreed

[@flavortown3781]

Would you publish your port maps?

[@2STROKESTUFFING]

+Jacob Westphal I can next time I have the cylinder off.

[@anunentitledmotivatedmille7731]

Im thinking of getting a zeta engine with the 40mm ports and m8 fastners because my old engine just crapped out on me. It had about 40 miles on it when one day it wouldent start so i took it completely apart. Cracked the case the whole nine, after re assembly and a good cleaning i found it was still giveing me the same problems loss of compression. So i messed with the top end for a while now and found the leak comming from the side of the sparkplug manafold i look inside and theres a huge piece of the threads missing and it gose all the way to the out size like a drill hole threw the case towards the cooling fins. I jb weld some new threads and its all good right, well no its squeeking now im guessing its the head gasket. Its been outside all winter before i took it apart and cleaned it. Its getting a nice blue spark from the new cdi with the big red wire and new ngkb7hs spark plug. wtf is wrong with this thing???

[@anunentitledmotivatedmille7731]

Im running 2.5 oz a gallon of 80 something octane, all they have at the closest pump. Im about to fit a tin gasket if i can find some laying around. I also noticed the head kinda raises on one side when I trque it down lossing all compression i did sand the stock head and surface. Maybe its a bad head? Could i bring it back to life? What Im thinking is if i can't get this POS pk80 running. Then i probably whon't be able to get the zeda running if i run into problems i really feel beaten by this thing iv come so far.

[@2STROKESTUFFING]

A bad head sounds probable, try replacing it. Don't give up, you'll get there!

[@upsidedowndog1256]

Happy oudeyaar! Nice fab work on the ignition system. Good result so far. What kind of timing did the moped run at 20 Hp? 2.5 out of that engine is great, but I am sure more to come. Holland was the only place in Europe I ever spent New Years

[@2STROKESTUFFING]

+upside downdog Thanks! The Spx ran 16° at peak power.

[@DandSCreations]

KX65 pipe next!

[@DynamicEmpireInc]

what is your dyno program that you are using?

[@brzduk]

Do you reckon running an open header on these motors is safe?

[@2STROKESTUFFING]

+vtec godd Probably, but the noise!

[@brzduk]

2STROKE STUFFING haha a lil annoying at high rpm, but sounds fantastic at idle and lower rpm. Really has a nice grunt to it, sounds like a v8 for a little bit actually haha

[@asdf52708]

which secondary coil / spark plug did you use for this?

[@2STROKESTUFFING]

Generic scooter coil and an NGK BR8HS

[@asdf52708]

2STROKE STUFFING awesome, thanks for the reply man👍 I'm going to order one of these.

[@marioraja4229]

Do you recommend doing this tuning on a 125 2 stroke daily driver?

[@2STROKESTUFFING]

+Mario Raja Not really. Assuming your bike has a pipe, 25° ignition advance at peak power rpm is about 10° too much. Probable reason it works here is a combination of bad cylinder filling and low squish velocity/low turbulence - slow combustion.

[@marioraja4229]

2STROKE STUFFING okei thanks for the advice

[@adambrown2173]

did you up jet as well , or is that increase all from timing ?

[@2STROKESTUFFING]

+Adam Brown All from timing, seems to be running fine so haven't touched jetting yet. That might change with a pipe.

[@adambrown2173]

I'm surprised the bike liked so much timing at high rpm, restricted exhaust or poor port timing guess i'm going to have to wait and see

[@2STROKESTUFFING]

+Adam Brown It's probably a combination of bad cylinder filling and low squish velocity/low turbulence - slow combustion.

[@puchmaxi5591]

Howe long did held the batery on this thing ?

[@2STROKESTUFFING]

Draws about 0.5A or so.

[@puchmaxi5591]

2STROKE STUFFING what would you recommend me for an ignition from powerspark? i have 1 cylinder and would like to use it in the old day, i have not installed a 12v battery and do not want to install one. but operate with on-board power. does it work? sorry for the google translator, i'm coming from switzerland (german) I think your videos are cool and exciting, keep it up 👍🏻
