I've known and been riding with Jim for about 12 years and could write a novel about the things we've done and seen in those 12 years riding in the mountains. Recently started riding bike again and can't say enough about how fast you learn riding with Jim. He doesn't come right out and push you...
RE: snowmobile guide
I personally know Tony with Snowfarmers and ride with him. He's lived in Vale forever and knows every place there is to ride!(Probably won't / can't tell you about some though)
A friend of mine is a dealer and as far as I know the sun gear pins are pressed and riveted into the gear set so I don't think there is any way of rebuilding it,Just my 2 cents
