Just put this in my 2009 YZ250F an right after I got the bike back together and running I could tell a huge difference in the power. It almost threw me off the back because I wasn't expecting my bike to accelerate that much faster. The only down side is the higher cost of the gasoline you have to run, but if your serious about racing this is a must have!
As a general rule of thumb, a higher compression piston will give you more low end power in trade for higher RPM power.
