Yes, but thats why i told you to try the TBS in the first place. remember you were telling me about the bike dying at the limiter and i told you the TBS would probably remedy that because it did for me. I think if the bike doesn't dyno quite as high you should still consider leaving them in because that limiter problem just isn't right. Then again it's your call as to what matters most, but personally i'd be willing to lose an almost un-noticable bit of power to lose that limiter glitch. By the way, good tip on the diaphram.......wish i'd have thought of that when i spent a 1/2 hour once trying to get the frweakin thing in !
