It's time for a top end freshen up. I can do the rebuild myself but I need to know what size piston to order (66.34,5 or 6mm), the piston in it is measuring as little as 66.22. So that really doesn't give me any indication.Does anyone know what clearance is required between cylinder and piston?
Also where is the best place to measure the cylinder?
Cheers Big Ears.
