I have just ordered a WR450 EXP Rekluse auto clutch to put
in the XTR... After a lot of part number checking it turns
out the WR450 & XTR share the same fricton plates...
Part #5TA-16321-00
The Rekluse core EXP insert is a copy of the friction plate
just a lot thicker...

with the core EXP clutch you have a auto clutch as well as
still retaining the manual oparation... rev the motor so the
auto insert exspands & tightens the clutch stack then you
can use the manual clutch pretty much as normal...
Be interesting to see if the gamble works out.. $649nz

Pic is of a XR650R unit... they also make a units for the KTM 690 & 990
so the power out put of the XTR isn't a issue....there is diffrent weight wedges
so there might be a bit of playing around needed...

I have a lot of work ahead of me on it over the winter.... Showa USD forks to
go in.. Still waiting for them to come back after a re-valve/re-spring..
Ohlins rear shock... waiting for new discs to show up... wave rotor on the rear
& a 320mm wave rotor for the front.. still got to order a rally raid front fairing..
It will be a totaly diffrent bike when it rolls out of the shed...
