ok here is my issue, I just recently bought a 07' cbr1000rr and have put about 1k miles on it. so right now im at just over 10k miles. When i first took the bike out it ran perfectly. Acceleration and handling was a dream. I have done general upkeep. making sure tire pressure, oil/fluid levels, etc are all good before going out. Just recently I began having issues while at higher speeds. once I am in 6th gear approx 8k RPM (~120 MPH) the bike stops accelerating. not like its hitting a rev limiter and bouncing more like a speed limiter where in it just holds 8k rpm 120 mph and just cruises. I thought I might have a bent/kinked fuel or vent line so i checked them. no problems. took the bike back out and it accelerated to 145 mph no problem. slowed down for a quarter mile then began to accelerate again. ONCE AGAIN it stopped at 8-9k RPM 120 mph and wouldnt go any further. any ideas??? here is what I have done to the bike. Full two brothers exhaust, K&N air filter, Power Commander III, speedohealer, HID headlight kit, LED strips around the inside of the frame. PLEASE HELP!!!
