Re: Motorized Bicycle Take a Tip...Leave a Tip
Okay so I found the problem when I got the motor the bolts that run through the crankcase were not bottomed out so I fixed that. Runs better still not where it was when I first got it. Had it up to 31 the top speed now is 18. It's a grubee skyhawk 66cc engine stock with a CNS carburetor. I did mess with the air enrichment screw but would that cause me to lose that much speed? Any suggestions?
