Get the chain deal solid.get you smaller rear sprocket. Little cv fine tuning if applicable .might end up the best set up ever for tooling the town. Sure seemed super smooth and definitely a motor saver..baddest looking pull starter ever kinda seen. Must have missed video of that set up. With cv you can fix the engine clutch 100 % locked up ? Yes. No. Great job
Yes the engine clutch area is 100% locked up it's where I mounted the pull starter as well 😂 custom clutch output shaft. yeah I was thinking 30t sprocket it has tons low end power. I had to make many custom parts foundry wise to pull this off. I used 2 old end mill shanks poured cast iron weights. It's the secret sauce to making CVT work correctly of the engines already internal gear reduction. Then poured an aluminum plate to match up my pull starter. (Tons of short videos as I built it) never bothered to even make videos. To much hate over every build. Gets way to toxic with idiot elites as I call the group 😂. It's why I always said I loved your channel's best info on stuff around. Don't take no shit from the idiots Brian.
They all talk constantly trash. give them all a
🖕😄🖕 With a smile is how I roll with it lol

@@BuildBreakFix ahhh yep its definitely the baddest pull start I have seen. The cv set up sure seemed silky smooth. Love to see some vids on casting parts . I find all that stuff super Interesting. Great job. Thanks for the short.
@@BuildBreakFixI don't no crap about alot of stuff. But the mph stuff and assholes is exactly why I stopped messing with bicycles. The cv set up for me sounded ideal. Sure seems like a engine saver. Once you were at speed and able to let off the throttle and still maintain same mph with about 1/2 the rpm. That's when I thought super cool set up. People are clueless about function. Or unrealistic. If you can gear it so it runs ehh 40 to 50 and still pull like it does.that definitely is a cool set up. Great job.
@2strokecarbtuningportingin187 thanks man! Means a lot to me hearing that from you! 🍺😉👍 A voice of common sense in this hobby!
The motor sounds great. Glad you've proved that the CVT can work. Looking forward to further tests and runs.Happy Trails.
you should see the withheld for review section.... This hobby so toxic not open to any new ideas!
Someone has to say it!!! You build some of the coolest shit in the motor bicycle community!!
Lol thanks man! Glad few people enjoy the odd builds. All in good fun. I'm in no race like most try to be. Just enjoy building stuff!
Cool beans sounds awesome brother just working out the bugs you'll have it
Soon I hope. Has potential to be a monster 😆
That is fricking amazing love to see more of it when it is running right 👍
Soon we need some upgrades before we take her to the bank for the money runs 😆
Bro looks like an absolute beauty to ride sounds good too!!
Thing is fun as hell to ride. Once fix up wheels and make a pedal crank. Will play with fire and see what she has in her on back strip. Nice 8 mile long 45mph road
@@BuildBreakFix 😎😎🚴🏼♂️💨💨💨
Sweet. I wish they made smaller CVT's
It works! Took a bit of reengineering. Still room for lots of improvements
It wouldn't be impossible to machine a mini comet style cvt but it would take a lot of time on a mini lathe. CNC would be faster but super expensive unless you are a CNC machinist with after hours access. On the bright side: it is relatively easy to machine a cone and a splined shaft, just time consuming.
20 years ago you could get a x2 cvt for cheap from a bunch of places. Now these are hens teeth.
@ShinyUmbreon765 not sure what you mean? I used a CNC mill to cut All the parts
😮😮😮 again, you have out done yourself, brother. The pull start is money. Can't wait for you to get the last bugs out. Also, that engine pops even with the silence! 🎉🎉🎉❤❤
yes lol it would be loud as f.... if i didn't have it on it lolz!
(¬‿¬) So much held for review comments. Why are so many angry over this build lol.............. I hit a nerve someplace big with this one!
I sure do agree on that... Sure glad it's a 4stroke!! Pull start or power start it the way to go!! Love my two 4stroke bikes
BTW... Sounds & running good brother, while ya keep the chain on 'er!!
Thanks for the ride along & be safe!!🤙
Now thats thinking outside of the box! Nice work
thank you! appreciate it! 👍
I love this build I feel it's far superior to the regular China doll. Having any kind of gear ratio That can change while you're ridding makes all the difference
It should be an "add on kit" seriously it's very nice addition to a China Doll
@BuildBreakFix If it was an add on kit I'd buy a two stroke for just that reason I love my 4 strokes, but that would be a pretty tempting 2 stroke.
❤🎉😊pretty cool! Fun fun fun
If possible can you make a video detailing every step of this build. I’d like to make one similar to it using a phantom 85 kit but try as I might I can’t just eyeball your video and be able to replicate it hahaha. Love your content. This build is something I am hoping becomes mainstream.
Just a personal build. 😜👍
Great job 👍
Thanks 👍
sounds great bro
Thank man! Getting closer to dialing in everything. I would watch UA-cam to help figure it out but I get tired of watching my own videos 🤣👍
Cvt transmissions work the best when they engage at power band rpm.
Yes sir! When I get the balls to run it up 😆 will find out. Really need to fix the bike up some first though
The driver pully needs more centrifugal weight, it should slightly grip the belt at idle. The gear ratio on these engines are 4:1 from the driver shaft.
My drive pulley weights are poured cast iron with two end mill shanks as guide pins 😜👍
@@BuildBreakFix Lol it works👍 I'm glad you proved that its possible. It would be cool if you could figure out the rpm of that driver pully. I know those 2 stokes red line around 10,000 right? I'm guessing the pully spins at 2,500 rpm tops.
@@Few.Be.There.That.Find.It. I have actually lol. Starts to open at 750rpms, fully opens at 1800. Driven pulley is fully open when engine is around 7500rpms. So anything after say 8k is 1.8 to 2.4 gear ratio advantage. Will it overcome friction? Maybe? Dono.... But going to find out lol. Yes that drive pulley is custom made 😅 you are only one to ask about it still after weeks of building this. Everyone thinks I was going to just use stock parts 🤫. I have a coal forge. Casted my pin parts in oil sand two weeks ago. Actually had to remove weight 😅 had ratios backwards had to edit it lol
@@BuildBreakFix I love your ingenuity man 👍This thing is a game changer
I would have thought you needed a bigger rear sprocket, awesome that you can go lower
I need a smaller one actually lol. Low geared still!
@@BuildBreakFix that's good. Should make the riding experience smoother, and keep down the rpm
A 44 on the rear would be a wheelie monster. I couldn't imagine a 56.
Nice bike was rippin
About to go alot faster 😆
You should go on a trip and make some of the motorized bicycle events/races wherever they happen
I get way to much hate to go to events lol Getting so many hate comments toward this build like always. Pissed off idiot elites that sell items. Because back yard hobbyist did something new. I got attacked other night on jarrads live chat even called lier lolz never actually had refferance to what exactly i lied about in any of my 660 videos lol You would get it if you saw the held for review section how many hate this video 23 dislikes.
@BuildBreakFix well you sir run my favorite channel and I get excited everytime I see you posted I wish more people would just follow along cause you have come up with so many brilliant ideas I've commented it before and I'll say it again i wish you were one of my neighbors keep up the great content and don't let them get to you just cause you're looking for the next best thing while there stuck in the passed
@connorday4329 😆 my neighbors all end up standing in my garage at some point talking. Lol they are all gear heads some of the crazy fixes come from the old timers that hang out. Great company and yeah learn lots of crazy tricks
@@BuildBreakFixyea I definitely threw in the towel on jarrods live. Seems like his channel got taken over by asshats .
Awesome work 😅
Thank you so much 😀
Maybe mad scientist us a small CVT made especially for these engines? Id buy one if you did ...
Gotta get this one working perfectly first lol
@@BuildBreakFix right on Brother.
Find out the right gear ratios and such.
It'd be cool if there was a smaller one that could be designed and easily adapted to these type engines.
I'm not one to be always thinking about money or anything, but I bet that you could sell lots of them.
CNC router all the parts, would probably be no easy feat.
The design of a cvt is simple, getting one made in the usa for less than 600 dollars a unit isn't.
Ideally the cvt would be on the right side of the engine, and replace the internal gear reduction. A 2:1 range that's from 8:1 reduction to a 4:1 reduction would work well for most builds.
However since cost is the concern, replacing the internal reduction with a stock comet clone and putting a pull starter on the magneto side is better. If I remember right the pawls are what fail followed by the cord on those. You would need a big sprocket on a jackshaft after the cvt.
I don't think I could handle the insane sound it makes 😂
Very loud! Even though a silencer! Off is even more crazy ua-cam.com/users/shortsR_RjkV2YNb8?si=x9aePjeSbzvuOr_F
Do you like that style chain tensioner? I've heard good things and bad things about them
Good on my old build on that bike. Bad with current one. Problem is they sit crooked but are super stable and stiff
Pretty cool I always wanted to make a small mini bike or a go kart with a tiny 2 stroke engine, a china doll with a pill start and torque converter would make my idea posible Any tutorial on how to do those mods ??
This was a one of a kind personal build 😉👍
A 212 with a comet will be much cheaper and easier.
@@ShinyUmbreon765 your right but i have done it already and also predator 420 , i want to try something small and 2 stroke
Nice job very cool 😎 one question on China dolls which minarelli can be used vertical or horizontal I think the only difference is the exhaust flange position right?
Vertical has an intake on top end. Horizontal is case reed
@@BuildBreakFix Thank you.I've wondered about that, but never remembered to ask.
@@BuildBreakFix aaah 👍 well who knows, knows 😃
I wonder if the pulleys from one of the Chinese scooters would work 🤔
Pulleys? Like belt drive?
@@BuildBreakFix yea like the variation assembly from one of those scooters, they seem smaller and there seems to be plenty of performance options with how people race those scooters
Get a non runner off marker place and pull it apart. See how much machining it looks lile it would take.
wow men how do u do thats
Crazy build right! Sold first one for big $$$
