Gearing and clutching

[troff18]

What shops in western Canada are going to be the best to deal with getting a clutching setup and gearing on an alpha.

Going to be switching the track on my 20 154" to the 2.6" from the 3". As far as I've found doing research the 20's came with a 7T-3.5 pitch driver and gears are 19T and 50T. The 21's come with a 9T-2.86 pitch driver and gears are 19T and 50T as well. Not exactly sure how this is going to affect the drive ratio. Also the clutching I have in right now seems like it doesn't load the sled up enough, seems like I drive through the secondary too quick.

I would go with Jerry at Central Sled in Wetaskawin. By far the best arctic cat dealer with the best customer service in Alberta.

With the driver change you are gearing up slightly. The 2.6 will be easier to turn so it may be a wash and just get you more track speed and the same concern. Personally i would try it first, as with changes I like to make one at a time. If you are going thru the secondary to quick after the track change then you have gearing and or clutching options. I second dealing with Central Sled best Cat and Yamaha dealer around.
