Bit the bullet after a pin broke on the standared one. They are alot better than standared also cheeper than a new top end. Im not sure what sort of gains you get on a standared engine,but all I have done is pipes air fillter small bit of top end work and was on dyno at 66bhp

My old powervalves were worn so I fitted solid, one piece items. Bike was horrible to ride, no good up hills in tight corners, and impossible in traffic. Purchased some cougar red items, and in combination with arrow exhausts and af1 air filter it was dynoed at 66.46 hp. All low rev issues are gone, all tight, steep hill corner issues are gone, all traffic issues are gone. The cougar red valves picked up an extra 3 hp over the solid ones. The bike (1997 RS250) is beautiful to ride and the power is brutal for a 250 2 stroke, I couldn't be happier. Mac Henderson
