This may sound like a crazy rumour but I have twice received the same information – get the right information, meaning part number and one can often get a perfect match for a part used in a car engine as well as a motorcycle engine. I am wary of this because of engine capacity, piston sizes are bigger in car engines. But car engines have got smaller. Torque is different but this has a lot to do with cam lobe design. Anyone out there that can throw some light on this?
