I've had my new 2009 FZ6 for 4 months now. I found the clutch engagement range and lever force required to be unacceptable. It's not a cable issue, it's a leverage issue in addition to the internal clutch design. I first purchesed the ASV levers for the adjustability of lever reach. I then purchased two new clutch slave levers (lever at the engine end of cable), are not expensive parts, around $17 each through the Yamaha dealer. I then removed the splined shaft end off of one slave lever, and removed the cable pull off the other lever. With some additional modification, I joined the two parts into one longer slave lever, going from a stock length of 30mm center-to-center to a new length of 45mm center-to-center. Oh my, what a difference. Hand lever force is significantly reduced, and even better, I can now feel a range and degree of engagement, and actually control how much friction between disengaged and full clutch engagement. My FZ6 clutch is now a pleasure. Of course, hand lever travel is longer, so this requires precise minimal adjustment of clutch free-play. I have small hands, so I have the ASV clutch lever adjust for the closest postion to the bar. What this tells me is that the stock lever will work just fine with this slave lever modification, since my ASV lever is at about the same position, or maybe a little closer to the bar, as the stock lever. I have good photographs of the slave lever mod at home. If I can figure out how to post photos here, I will later.
