2018 CRF450R Clutch

So MXA says to replace the clutch judder spring with a regular clutch plate, but the parts breakdown shows three different part numbers for the plates.

Anyone know which plates should be used?

The innermost (closest to center cases of engine) friction plate is thinner to allow a place for the judder spring to nest. Replace that innermost thin friction plate with one additional of the middle friction plates. Of course you want to remove the judder spring and washer. The outermost friction plate is also unique as its fiber patches are shaped differently.

By the way, for those considering doing this mod, the MXA instructions are incorrect. The correct part number of the plate to install in place of 22201-MBN- 670 is 22201-MEN-670. The same as the 5 other plates in the assembly.
