I had someone ask me to do it, and they sent me the instructions. It uses a template to reposition the driveshaft, and you replace the chaincase with a different one.

If I can find htem, I'll post them for you.

Just like what ugly old poo kid said, find a chaincase that's the length you want(usually about 2-3" longer) do some math and figure out where you want the chaincase and how far back/down it is from the original position. Then cut some new holes and bolt your driveshaft back in. Many people also make a support plate for the PTO side of the bulkhead.

Exactly.
I will add that I think this IS one of those jobs that you really need to know what you are doing, or you'd better pay some one to do it.
Get it wrong and you can become very mechanically screwed quickly.

Lots of work. Make sure you know what you're doing. Check Snowest too. Many mtn riders did it it before the days of the big tracked sleds [1990's].


Also check here for a kit review--

ok so if i role the chain case, wont i have to do some remounting on the rear suspension? If the drive axle is moved back then isnt that going to make the track loose? Or can you make up the slack in the track adjusters on the skid?

The chaincase to use is from a 98 RMK. I have never done it but I know a guy who did it to his prostock 1000 speedrun sled so he could run 10 tooth drivers.

Huge project! I did my dragon over the summer. Used Holz racing products' kit. Install took me about forty hours taking my time. If you're not a mechanically inclined don't even start. But if you are you'll be ok, just take your time.

Here is my topic on my install. Different than your sled, but it gives you an idea on what it involves.
