I agree Fishinyak, Yamaha did listen to many complaints. I also agree your sled is still merely middle aged and will run much longer.
1. For cold hands, get 2007 Attak handle bars and Rock's Yamaheater. Your hands will roast. Amazing what a difference. One of Yamaha's cold hands problems I believe is the aerodynamics tend to direct cold air rights at your hands, so also wear guantlets on really cold days, just to keep the cold air off.
2. Carver. Call Mike Carver up about your shock problems. He is really good. Something must have gone wrong, maybe relaying your personal information (weight, riding style, etc.) or some thing like that.
IMO, your shock issue is most likely a spring issue, not a revalve issue. The spring is what holds the weight of the sled. Are you a big guy? If you weigh over 250 or more you need a larger spring. no revalving in the world can solve that issue. But then again, Carver should have put a different spring on it when he had it for you. Would have been better customer service!
3. I completely agree that a Fox Float in the rear of the Mono would rock!!!!
As long as the center to center measurements are the same, and as long as the shock fits in the allowed space down in skid, the Fox Float should bolt right in......
One issue with Floats I know is sometimes they don't have long enough flanges on the ends so they don't fit into some skids. For instance, I could not fit Floats into the rear of my Mnt Viper because of this very issue, and instead I opted for Ohlins.
So for the Mono 1) either the Fox Float fit, 2) Yamaha changed something, or 3) Fox made the Flanges longer for the new Float shock...
