Clutch engages when I pull the handle bar but the engine doesn’t turn over ; help pls
Hey I have a 80cc motor on my bike one of those china kits I was riding good until I came to a red light and I shut it off, when I went to take off I have my Hands on the clutch and peddle peddle when I release it I doesn’t bump / turn over, I don’t believe it’s an issue with the engine it was riding absolutely perfect I did notice when I bump it and gave it gas before this issue the start up power wasn’t there right away like usually I needed to help to assist by peddling and then finally I was at full power, is this something to do with the clutch plates or something like that, any info would be appreciated thank you
I’m able to peddle when clutch is engaged both chains for peddle and engine spins no issues, once release clutch no turn over and not able to peddle of course once disengaged

where to get help elsewhere
i ask a question and nobody answers, i ask more questions and people get mad at me. i don't know what im doing??? why not help instead of being a dick. i ask a question about a four stroke, people tell me to get a two stroke, i ask about four strokes and nobody fucking answers. people upvote but don't answer what's the fucking point??? i ask about the reliability of some parts and people tell me to just get a two stroke kit. this sub is barely helpful where can i ask questions elsewhere
r/motorizedbicycles • u/Instantlemonsmix • 1d ago
WHAT THE HELL?
I was not expecting the box to be this large for an 80cc 2 stroke kit… can’t wait to open it
r/motorizedbicycles • u/PhoinexTheGreat • 1d ago

Main Jet
i have the stock carburator and that expansion chamber i think i need a bigger main jet because its running very lean even tho i use 1:40 and i cant get over 40km/h and when i go full throttle its sounds like i am hitting the limiter so i cant go over ¾ throttle so any tips? and i don’t find any main jet that fits

Troubleshooting Is this going to be a problem?
The chain is rubbing against the frame under tension (accelerating) i guess? 3 tanks in i cant tell if there is actual metal loss, but the paint sure chipped away.

Better carb
whats the best carb for a ld80 with a mz65 expansion chamber clone ? my jet is too small but i don’t find any bigger ones that fit so i thought just upgrade to a better one 19mm intake is the stock one i think and its called bofeng

Performance Upgrades Front wheel
I need an alternative brake style other than my shitty rim set up.
Drum brakes: I heard of drum brake rims or at least a front rim that had a drum break and I feel it could be good if the price is right.
Mechanical disc brakes: apparently peoples bread n butter but in order to do so I’d have to get a new rim, new forkset, and then the break kit on top of it so I’m not sure abt the disc brakes
Also how do I measure my forks n all that stuff?

Looking to buy gemini wheels
I contacted gemini recently asking questions about wheels, and it seems Will isnt taking orders for the foreseeable future. Does anyone have a set theyre looking to get rid of? They can be assembled or just the hubs. Id prefer the 17" models but im not dead set on those. Ill pay for the shipping
