I've owned an 80cc motorized bike for 2 months now. Out of the blue i get on my bike like usual after a day of not riding it and i drop the clutch, starts like normal, i go to twist the throttle and all i can hear is a hum sound of the engine turning over (the engine turns over just fine) as i twist the throttle however no power or acceleration. (when i twist the throttle, the hum sound increases for a second but it doesn't accelerate) I did this a few times and i was getting to the point where the engine would have these quick bursts of acceleration (a loud popping noise would go followed by the quick acceleration burst) but it would never actually take off.
it sounded like it really wanted to start and was on the verge of but just couldn't get there. i have spark as i tested it, my cables are ordered correctly and my clutch is fine. everything seems fine, im getting fuel, carb isn't flooded as ive taken it apart, cleaned it etc. ive cleaned out the chamber where the piston is. im very confused as everything seems fine. my mate came over and i put his spark plug on my bike and it worked perfectly. my bike ran like normal, so i thought it was spark related however he put my spark plug on his bike and his bike took off perfectly as well confusing both of us. everything was all good until i left the bike for a few hours and went to go ride it again later but same problem.
i don't know if its the engine miss firing but now when i try with the different spark plug in im getting more of those pop pop pop noises (its sounds like the noise it would normally make if it was running fine) and as these popping noises go off i feel a little bit of acceleration everytime it pops, but when its not making the popping noise it doesn't accelerate. im very confused at the moment and am just wanting to ride again. i keep my bike outside, under shelter obviously so no rain gets on it, and currently its cold where i am so idk if that has anything to do with it.
i have tried playing around with the carb, specifically the choke, trying to cold start it using choke and what not but nothing seems to work. what confuses me a lot is that it happened out of no where, it has been running flawlessly for months and randomly it does this, i didn't crash it or anything like that. keep in mind ive well gone past the break in period and have been running a 50:1 fuel ratio constantly. i dont know what running rich fuel and whatnot means so ive kinda just stuck to that ratio. i fill up a jerry can of 5 Litres of fuel and pour in 100 ML of 2 stroke engine oil into the 5 L making one big mix. could it be fuel ratio related.
ive gone through all kinds of forums and tried everything. please help!
