Cheers for the info. I have no idea on the engine size yet i havent had chance to check. It came in this afternoon and i just got it running for the craic round the yard. Wheni heard how sweet it was i started getting ideas! Ha. I thought with a decent exhaust it'd sound nice but wasnt sure if the carb'd ones were worth messing wth over an injection for example. Love that one above btw! I dont sppose you know how hard it is to mount do you?
