I can get a killer deal on GYT-R '04/'05 YZ 450 Clutch Basket, Inner Hub, and pressure plate. The problem is that I have a 2003 450. I was on the Yamaha-Motor website and it shows 03 and 04 basket part #s to be the same, but inner hub is different. Is the inner hub a new part that will work in a 2003? Has anyone done this? Any ideas on which plates I should use: 04 or the a 426 inner plate like I have on my stock 03? Any info is greatly appreciated. Thanks.
