My 1997 600 Bandit needs some (a lot of?) work: New discs fornt & back. Exhaust fitted properly (bit of metal holding exhaust to down pipes missing). New sprockets. (and chain, probably). Service - bike pulls ok to about 3.5K, then chugs like a tractor, then is OK again at higher revs, and generally backfires when engine braking. (To do with exhaust?) Speedo Cable Fork seals I think this means loads of cash which I don't have, and I only really use it for commuting to work each day. (12 miles each way) Can I part-ex such a heap? Is it worth getting it fixed before part-exing? Should I go to a breakers & get the bits & have those fitted? Any advice helpful
