Looking at the run files after Kris's Dyno run I was wondering what all the spikes were, clutch slip or wheel slip on the Dyno, so I asked a good friend to have a look at the run files & he said the clutch was slipping, so Kris pulled his clutch down today & the clutch was fried & that is with the uprated clutch.

Kris was running an extra clutch plate + heavy duty springs at the time, the XT's clutch is quite different to the Raptors, Kris could not adapt the clutch hubs from the Raptor to the XT's motor.

We will wait for Kris & he can explain further.

Clutch Mods

Thats right Kev

I had removed the half fibre plate and replaced it with a full fibre plus heavy duty springs,but thats not enough I have now fitted a new complete raptor700 set of clutch plates with 2 steels back to back and have ordered some heavy springs from DL700, see if this holds.
