Most of this will relate to Sno-jet and Kawasaki fixes as that is my specialty
Parts like rollers, weights and ramps could be changed very quickly on a hex clutch. Other clutches were not so easily tuned. I have a list here of major points on a hex clutch to watch out for.
If you keep all of these components working right your clutch and sled will keep working up to par.

The Arctic Cat Hex Clutch
This highly adjustable clutch was not only used by Arctic Cat
but by other manufacturers as well. Mercury, Sno-jet and Rupp along with a few others used the hex clutch as original equipment. It had many points of easy adjustment and could be easily tailored and tuned for many engine applications.

For any of you that have broke this part and are hard pressed to find a replacement, try this!
Just about every snowmobile ever made has some sort of stickers on it to
advertise the make, model, warning stickers, engine make and so on.
When these stickers go through 20 or more years they tend to get faded, scratched, painted over or sometimes removed completely. Sometimes there's decals on sleds that are not original and maybe you want to remove them.
I've seen everything from 5 layers of license decals to Sugarloaf USA stickers on sleds and I must say sometimes they weren't always easy to take off until I discovered some good methods.
A heat gun is the best thing to start with when removing unwanted or old decals that need to be replaced. (Not recommended for plastic surfaces) fire some heat at the decal you want to take off. Make quick strokes over the decal as if you were spray painting it. Keep about 3 inches away from it. Sometimes you will see the sticker bubble up a bit. That means you are getting a little too hot and could damage the surface it is on. When you've heated the decal up, start to peel it off. When you peel the edge up prepare a can of paint thinner and a brush. Brush the thinner on between the decal you are peeling off and the surface that you want it off of. Work in a pattern of 'brush some thinner on, peel a bit more decal off, brush more, peel more....'.
If you are working with a plastic surface try to peel up the decal without using any heat and then use the paint thinner method.
