I have a 2007 rm 85 and want a way to add 3 more horsepower to match with a 13 kx85 we think to mill of part of the head will add a little bit that I need we want a way to add horsepower with out it being a illegal bike. The bike has a pro circuit the works pipe with v-force threads and namuria piston suggestions.

Increasing compression does not give anything more than a slight boost in power.
Maybe the other bike has more horsepower but yours may have a better spread of power which is just as advantageous. With pipe changes you can get more power but make it less rideable because the power will be squeezed into a smaller range of rpm.
