I purchased a new speedo unit for my 2001 WR426. The gear box unit assembly (http://oem.thumperta...frontwheel.aspx) part #13, makes the wheel not spin as freely as i would like. Does anyone know of a replacement part that is a space, and would remove #13 all together?

Thanks,

On the '01s, you can use the YZ spacer to eliminate the odo drive. You need to also use the YZ seal on the bearing, as the WR bearing is unsealed. That's what I did on my 01 WR when I added a Trail Tech Endurance computer. Works great.

hopefully i am understanding you correctly. By looking at this (http://www.yamahapar...tion_detail.asp) looking at an 01 YZ 426 front wheel, i think i need part #13 and part #4 to get the spacer, plus the bearing?

please let me know if that is correct. I also replaced the stock odo with trail tech. The wheel does not spin freely at all, so hopefully these 2 parts would be the difference.

Thanks!

You can also just remove the ring gear from #13 to reduce some of the drag since there is no cable to turn.

You are correct. #13 is the spacer, and #4 is the seal. If you are going to replace bearings, pick up a pivot works, moose, or other YZ426 front wheel bearing kit, and yu will be good yo go. This trick doesn't work on 02's by the way, just 01 and earlier.

I went with one of these on my '04 & have had no problems.
