Does anyone have one of these on there quads?? What kind of power can these motors be modded to make?

Poking around, I see claims of about 70hp for the XR650R.

Pumping out a full 25 percent more power than the XR600R, the most powerful engine in XR history generates more performance than even the factory XR628R raced by Johnny Campbell. In stock trim, the 650 makes 43 horsepower at 6750 rpm. Peak torque arrives 1250 revs earlier at 5500 rpm. Honda also offers simple intake, exhaust and carburetor parts to boost the XR650R's peak to 55 horsepower.

Also:

- Compact, lightweight engine weighs only 88 pounds.

Can anyone tell me how much 400EX and 450R motors weight, by comparison?

I'm guessing 70-75lbs or so?
