Does anyone have a WORKING CHAIN DRIVEN chain saw bike. If so what size is your engine. Did you have to use a jackshaft. What is your gearing. Can you still use your pedals.

i had a scooter i built with a 32cc poulan chainsaw motor . it worked great till the motor fried . i shouldn,t have taken off the fan cowling . i welded a 10 tooth sprocket to the original chainsaw clutch ran that to a 20tooth on a jackshaft then a 12tooth from the shaft to a 72 tooth on the wheel , 12inch wheel . it took off slow but would do about 40km/h
it was one of those scooters with 12inch wheels you stand on and push with your feet .
i mounted the motor in front of the rear tire , on top of a jackshaft box i made from a 6x6 piece of square tube . wored awsome . till .
like i said , untill the motor siezed , because i removed the cooling shrowd
