Re: what did you do to your motorized bicycle today?
Today i tested my top end rebuild. realized it wasnt quite right. did some quick measuring and found that the cylinder i got was actually 1mm taller on the base. so much sanding and some port adjusting later its back together with a new piston fresh rings and a new wristpin bearing. silver its 5x heavier than the original. Test starting tomorrow and a 60-100m ride!
