Viper clutch

[graham_r]

Now that Yamaha is using the cat chassis what will it take to use a Yamaha driven clutch on an M8?

In the viper does Yamaha use a Yamaha jackshaft to match the Yamaha clutch? Or did the match their clutch splines to the cat shaft?

The best clutching I have ever had was on a Yamaha. Would like to try this swap.

99% sure that the Viper uses a different jack shaft. Both the XF7000 and Viper use same manual chain adjuster, gears and chain. Also both the XF7000 and Viper used a fixed mounted jack shaft which is different then the TCL equipped M8000.
I believe that the Viper shaft won't fit a M8000 due to the differences between the fixed mounting and TCL design.
