I know it sounds daft and almost impossible to diagnose without hearing it but here goes anyway, I am looking at a really good 98 Fazer it's got no problems I can find except an after market silencer and a strange squeak when I rotate the chain, best I can make out is it appears to come near or forwards of the plastic/rubber guide on top of swing arm? I doubt if it's anything serious but just thought I would throw it out there for any feedback. It is not constant but appears every once or twice a revolution of the chain, if he drops his crazy asking price I will probably buy and strip and clean guide and hope for the best, thanks for any help.
Doesn't matter in the end of the day I walked away, and have found a nice 99 minter with full service history and hard to believe 4700 miles, I wonder why some people buy bikes, but maybe now I'm in my 60's I too will only just roll her out on the 2 or 3 sunny day's we get here in Northern Ireland.
