Well everyone, I've finally finished my machine. It works great! I have ridden a '05 600 and feel that mine rides and handles better than it. In the rear I have shocks and springs from the front of an '02 or '03 viper and they work well. The preload is pretty well maxed but they aren't harsh and I haven't bottomed out hard yet. '03 yz450 forks with .56 springs - may have to do some valving here, they seem a little soft on the dampening. I put a 521 l/c out of a '91 formula plus in which seems to have lots of power for now anyways! Std. ski mount with the twin axis ski works better than I expected on the trails and great in the powder. It looks like a '03 503 fanner, just works better I think. I'll try for some pics, not real computer friendly...
