Hey bill,
Plug wires are easy. But first i would get a secound opinion on that, a 2000 shouldn't need it, but anyway, just buy the new set and use the ones on there as a example and do one at a time, just like a car. I ride polaris, but it probably isnt different really, the just unplug and plug back in, best thing to do is run to your local dealer and have then pull out a new part and take a good look at it and see if it needs replaceing and how to do it. On the clutch, no, 4500 isnt too high, especially on a mountain sled, my rmk engauges at about 44-4500 stock as well. Mountain sleds arn't made for top end speed, so there clutches enguage differently with generally different clutch weights. Hope this helps, any other questions or if i just confused you, fell free to hit me back.
