[QUOTE="JJDirt, post: 1400478, member: 120498"] Well I would assume there would be more exhaust when your full out but compression would increase the power so having it closed or partly closed would create more power, I don't know enough to make any bets on it, and the guys at yamaha won't tell me without them ripping the engine apart and assemblying it to "guarantee" it's done right, since I don't have the money for it and I would rather do it myself so I learn, that isn't happening. I'm not even sure if it can be explained or if it depends on certain variables. I'll try to upload some pictures so I can show what I mean. [/QUOTE]
