Re: 80cc powerking motor 30km/h top speed
Try a new spark plug..
My engine after break-in started acting weird the engine wouldnt idle well as if it was gonna die any moment..
Couldn't ride at all.. I would twist the throttle and go but then the power is just weird for 1 sec i could accelerate then the next i would lose my power and then it'll come back..
After i got a new plug everything went well..
I guess during break all the 16:1 oil killed my spark plug
