after recently crashing my bike at about 65 mph and putting most of it back together and getting it running, it started running really rough. i noticed that the little servo that pulls the cables connected to the butterfly valves in the exhaust is not pulling them open.. i heard they only open at 5K and greater RPMS? is that correct? i also heard that once the tip over sensor triggers your other sensors need to be reset? i most definantly could be wrong.. anyways could the butterflies not opening cause my R1 to sputter erratic... and run awful? please respond with even a guess.. i couldnt get one response in my other posts.
