I've got an exhaust pipe that is either cracked or has a dodgy joint coming from the rear cylinder of the spada. It's been there for a while but being able to hear it over wind and music while out today has got me motivated to at least consider it. Will it cause any problems if I just leave it as is? Can't really think of much other than perhaps a bit of back pressure on the rear cylinder exhaust, and I don't half mind the sound half bad either. Also the bike seems to be burning a bit of oil - not blowing smoke or anything, but just a progressive drop in level. I can't see how the two relate in any way whatsoever, but is there some way the pipe could be causing it? cheers.
