5 /5 Vince M: Old school class! Instantly gave me a cheap quote over the phone and said it would only take 3 days to rebore a 1 cylinder motorcycle. Later I took in the cylinder and he told me that I may be able to get away with just swapping the ring out instead of machining it after he took measurements on it. The moto repair shop in Arcata tried to charge me $60 buck just for measurements and advice.
