my cylinder keeps on scuffing up each time i rebuild it, the petrol and everything is fine and scuffs up worse everytime. my question is when i look at the cylinder there are two scuff marks, black going straight up from the middle induction port about an inche long. Is my cylinder out off round? can i keep on riding it for a bit longer, it runs fine and has heaps of compresion?
thanks for any help.
