500 H.O or 500
#5
I heard the clutch was different but won't know until someone runs the part numbers. People were making their own H.O.s with Scrambler parts before Polaris made H.O.s. I heard it was clutch, cam, carb. The airbox is different too.

The H.O. has 15-20% more power. Almost as much as a 600. I really felt the difference in mine. I'm not sure what the difference in top speed is, but the older 500 didn't launch like the H.O. does.
