Trusty powervalve cover
I have a trusty adjustable powervalve cover installed an my 300 ec ,2006 model. When I first thought about getting it I was concerned about how much difference it would make,compared to the cost. Previously I had an ltr cover which seemed to help bottom end thrust with the extra capacity.But the trusty one also has the larger capacity plus the adjustability. It has 10 settings. Turned down to 6 it runs like a trials bike,. Turned back up to the zero setting it runs just like stock .And turned around to -3 it runs more like a motocross bike . Now i have a bike for every situation just with the turn of a dial .
