Awesome!!! Thanks for the info!!! I will just go with the 9 tooth then as I just put in a new Ulmer clutch kit and don't want to have to mess with it!!! I am really anxious to run with the Stage II kit, I just got it put on last weekend!! Is there any advantage to putting the stock outside half-drivers back on??

I used skidoo part #504152552 9tooth 2.52.(about 60$ each)They will fit on the stock shaft.I'm pretty sure yamaha shaft is 1 1/16. Skidoo is 1 inch for a nice tight fit.I believe the warrior has 9 tooth drivers stock.If you go to 10 you will have to adjust gearing and clutching.You can fit up to 1.5 inch lug with 9 tooth drivers.To maintain adequate bulkhead clearance with 10 tooth drivers it may be necessary to use a shorter lug track.Advantage with larger drivers is supposed to be less rolling resistance(track doesn't have to wrap around the drivers as tight)Great mod,run track much looser,less ratcheting.

When I look up that number on Doo parts fishe it comes up as an 8 tooth 3.00" pitchdriver.
This will NOT fit a stock track, ONLY a 3.00" track.

Found the correct part number (#504152503 = 2.52 pitch 9 tooth) in this thread:

Ulmer may have these in stock.

Hope this helps!
