Hello, im Matt from south wales and im just about to start a chop project. Its a 70's chopper frame, girder forks and a Honda CB 550 four engine,. I can guarantee you gents ill be picking your brains as im no bike builder and no very little about engines. First bit of advice i need is whats the best route to go down with the engine? I have the Haynes manual for the bike, is best to sit down with the manual and the engine and go through it? Thanks in advance.
