:confused:I am considerng changing the gears in my 2000 YZ transmission to the WR gearing. The on-line parts site that I use has dropped the part numbers from thier web site, so I can't find which parts I need to price. I did a search here on the YZ and WR forums, but didn't find anything. Has anyone done this swap? Part numbers, costs and any tips whould be most appreciated. Actually - ANY help or ideas would be most appreciated.
