I had to relocate the carb on my bike for clearance, My spark plug boot barely touches the brake lines and has rubbed a bit of plastic off the brake line. I am using the CJ7Y plug BTW.

Check out how I did it... My MB PhotoStream It's not the prettiest, or the best. I'm thinking of ordering two intake and chopping them up and getting them welded together to it points out to the side like it does on my bike. The problem I have is the vibrations are amplified by the vinyl hose.
