Found the clutch cable on my 2006 FZ1n had nearly sheared through at the lever end. It had only lasted 6,000 miles, the mileage on the bike. Spend a lot of time replacing it (right pain to do) with a pattern cable (TSX). The lever action is very heavy, and was I seem to remember heavy with the original cable, but not as heavy.
Anybody any ideas why?? The cable can only be routed one way, and I do not think it is rubbing/dragging on anything. Is it the pattern cable?? clutch problem?? Bike works ok, without any clutch slip.
