Which ones would I need for a 04 mountain stock?

 

[POWERHAULIC]

Stock drivers are 9 tooth.
If you are not changing track height, same amount of teeth.
Depending what you need for bulkhead clearance will determine.

RX Mountains came from factroy with 8t drivers in 03/04/05, not 9t.
9t came on short tracks. I have a set in my junk pile if you want to see.

Thanks Red I am getting tired of ratcheting in the deep stuff and if I tighten the track it is too hard on the hyfax so new drivers are in order.

 

[POWERHAULIC]

Red, I thought the mountains had an 8t driver. So I went to the parts book, and they listed a 9t driver.
Prob. bad japan/english lang. conversion...lol

If you have bulkhead clearance, it would roll better w/9t drivers. Although you will have to regear accordingly.

Extroverts

I have 8-tooth extroverts on now with a 2" track. What would I need to go with to run a 2.5" track? I really don't want to mess with the gearing and clutching. I am real close on the tuning. My present extroverts are trashed from running the 159" too loose with the turbo.

P.S.--I already have a drop and roll with the MPI tunnel so clearance really isn't a problem.

I thought the shaft size of the Ski-doo's was 1/16" larger than that of the Yamahas, no? I was going to recommend these sprockets to a friend of mine with an RX-1 but I wouldn't based on the difference in the drive shaft size.

I have Wahl bros 9t 2.52" drivers on my sled. It has variuos levels of boost from 5 to 21lbs, 2300kms with no problems. I used the polaris ones with the 1" shaft, so less chance of slipping on the shaft. Lance I would think you could go with the 2.5 track with 9t 2.52" or 8t 3" drivers.

the rx mountain used a 8 tooth 2.52 pitch driver in them if you go to the 3 inch pitch drivers you ned to use 7 tooth if you use the 2.52 pitch ones you can run 9 tooth with a 2 inch track and not rub.

 

[hot rod rooster]

i have the 7 tooth 3" drivers and they are showing some wear in the extro teeth. if i did it again i don't think i would use the wahl bros ones unless they have changed thier plastic compound. i am running a 2.25 in track with only about a bit over a 1/4 inch clearance. the 2.5 inch trac was very tight and would rub untill it was tightened up.

Does Skidoo also carry the 7 tooth driver I need for the Apex? I could buy directly from Avid but I thought it migh be cheaper through a local Skidoo dealer than to pay customs clearance
