    Phillip correct me if I am wrong but I was under the impression that the 00-01 were different threads then the 02-08 I shafts on the GPR

    I know on the crank side GP's and GPR's are identical.
    I do remember back when I did the 2" extension upgrade years ago, you had to buy the coupler for the new shaft too.

    I had forgotten in 2002 Yamaha increased the diameter of the intermediate shaft - thanks for reminding me - now that I think of it I recall Fernando swearing at Yamaha for making this change - if need be we can probably drill and tap 1 of the couplers for the different threads used by the 2002 and up intermediate
