What should the top end speed be of a stock 2003 zr 900 sno pro be?

I was thinking the same thing as I have the same sled but not a sno-pro. I have had mine up to a clocked 99mph with me at 260lbs on the back. My clutch engages at about the 3800rpm mark and pulls like a clydsdale, cant stop her. I will do more twees to it and have a couple of more go's at a top speed and get back to you.
