My Yamaha FZ6 S2 has been a great weekday commuter workhorse, yet with enough beans for some weekend fun. However, it’s not without issue, in particular the clutch. Firstly, it’s very heavy on the hand, to the extent I was getting hand ache in the first few weeks of ownership and was convinced it needed a new clutch cable (which changed little!) Secondly, the clutch bite point is way out on the lever, with little distance before fully released, even when all correctly adjusted with free play to spec. This all adds up to clunky gear shifts that you can never quite smooth out, you just can’t get throttle blips timed nicely with the point of clutch engage.
Recently I stumbled across a simple mod that promised to improve the heavy FZ6 clutch, which entails swapping on the lower clutch push lever from an MT07. This is the lever at the lower end of the clutch cable protruding from the clutch case cover. The MT07 push lever is slightly longer and so affords greater leverage, and thus lightens the clutch action.
A common job on any bike with a cable clutch that’s done a few thousand miles or worse has had a snapped cable. As time progresses cutch cables will stretch, requiring adjustment to bring in the slack, but eventually, they will need replacing. Similarly, if they have frayed or kinked preventing easy movement a replacement is the best course of action. Here I’ll walk you through step by step how to replace a clutch cable on a Yamaha Fazer FZS 600 (1999-2003), but other bikes will be fairly similar, tending to vary only on how the bottom end of the cable connects to the clutch.
