Ok ,thanks, so it is as fast as the raptor then? the main issue is, are those atv's capable of driving in 60mph(100kp/h) in a mid rpm range?

No, 60mph would be the max for those machine.

The 35Hp, that is at the crank. it is down in the 20's at the wheels. I would get a 400EX it sounds like it will better suit you.

The only machines that will hit mid 60's at mid RPM range is the 450's and bigger. The 400EX will max out in the mid to upper 60's.

ok, thanks for the advice:) The problem about 400's and 450's is that they are twice expensive as the 300's and the 350's, because of high norwegian taxes when it comes to street legal atv's

LMAO... Then I'm pushing 100. The motor can do it. but gearing wouldn't be practical.

it will if I ever finish it... there is a guy here down the road from me that has a motorcycle dyno, if I can ever catch him home I'm going to dyno my quad before I replace the head and after. I will post a print-out of the results. I hoping for some where in the 40hp range once I'm done with everything.. Right now Im looking for a reasonable 400ex carb the cheapest one I found was on ebay but Im picky.

If i by then change the stock sprocket to one with more tooth(14->16?) then it won't be a problem:)

Being a solid rear axle you will burn through tires quick, plus turns will make the machine want to 3 wheel. They make sway bars for the front...
