Thank´s for the reply´s!
I don´t think that Vmax4´s had a specially fast year to them. They were pretty much the same, atleast the 800 ones ( 95 - 97 ). 750 had around 135 - 138 hp, depending on the year. 97 had better brakes, proaction skid and some other minor things, what made it the best year for V4´s.
And I´ve beaten 650 Polaris ( carb ) bad. He wasn´t even close, ever.
Quad piped, other wise stock V4 will put 170 hp out. lift the cylinders and lower the head, you´ll get 180. Do a big bore to 880 and you are in 190 - 200 range. 903 by Hauck get´s around 210hp. Turbo V4 750 had 280hp pump gas...
My V4 get´s better milage than my brother GYT-R twinpiped XT 600. Even when the XT was stock. BUT, when I pin the throttle, gas will flow! Best what I get out as milage wise from my V4 is 150 km / tank of gas. That is around 91 miles... Tank is only 38 litres / 10 gallon.
There been some really great condition V4´s on the market at
www.vmax4.com If someone is interested.
One thing why I like my sled so much, is the fact that there are 3 known 800 MountainMax´s in Finland, and I own one of them...

That is rare.
