IMO, they arent really worth the money for the little power you gain all it pretty much does is increase your spark a little and raise your revv limiter…when in reality raising the revv limiter on these doesnt increase power…just makes you able to stay in gears a little longer but sprocket changes do the same damn thing and only cost 15$ each/ does your quad now have a K and N filter? Lid removed? full exhaust and jetted?? even going to 18" tires makes a HUGE difference…thats all us motocross racers run…18" in rear, 20" up front. then mess around with sprockets…1 tooth down/up in the front sprocket is equal to 2 teeth down/up in the rear…bigger the rear sprocket, the more accleration…smaller the rear sprocket, the more top end… bigger front sprocket = top end, smaller front = accleration… then you play around with the two. --- _[View the full topic](https://forums.speedlife.net/t/anyone-want-to-hit-the-ice-this-weekend/241659)._
