Re: Top Speed, 80cc Chinese motor? what is the record?
I spent hours and hours with the dremel porting and matching. Removed the stock air box and just have the filter element there. Stock pipe with the end cap removed and shaped at the motor to match the port, shaped the intake side of the piston to the intake port and removed a little more weight on the inner edge of the other side. Rubbed cutting oil on the rings, bearings, wrist pin, anything that moved and went out and pedaled the **** out of it with no spark plug and got the motor spinning as much as I could before ever starting it. Got the chain very lubed and aligned, put really slippery racing grease in the wheel bearing cartridges. High compression billet head, pretty much tried to get everything as efficient and balanced as possible. I have about 3/4 of gallon of break in pre mix run thru it so far. Oh yea, I soldered and drilled the stock jet.
