i got a 49cc cateye pocket bike and when i start to accelerate it starts jerking. all the motor mounts are tight

jerking how? did you adjust your idle?

Sometimes when the idle is to low the motor starts jerking.

my best guess would be somthing is going wrong from your tank, to the carb, is the gas flow thru the line condsitant? run your motor and look at your gas line if its clear. if you can see the gas and then see air pockets , what im trying to get to is i think the gas flow is running in short bursts in the line, some gas will go thru followed by some air and so on. this has happened to me before

its getting plenty fuel. i take the bike down my drive way and back and it works fine and then when i start to accelerate the engine just jerks a lot i think it might be the clutch but im new with pocket bikes so im not sure.

its a little hard trying to guess how it is actually jerking, if its a brand new bike, the pistons probably arent broken in yet, what size cc?

[Beanscateye49]

49cc and its about 2 years old. the motor runs fine till i try to accelerate and the whole motor starts jerking and all motor mounts are tight.

how well did u look at the adjustments to your carb? I'd look at em again. My first goped did somthin like that and i adjusted the carb and it was fine.(mixture's and idle)
