Im having a sever loss of power when im in high rpm's like i stated its like im hitting a spot on my throttle where my bike wont pick up anymore. usually around 11-12k. i posted about this before to no avail expect people giving me dirty injectors, bad spark plugs, and that pretty much sums it up. Im still looking for help on this if any guru or master mechanic or ama racer wants to give me a tip or two id appreciate it greatly.. my air filter has been cleaned throughly, oil just changed 1000 miles ago.spark plugs just 150 miles ago. clutch is good runs fine at idle and low speeds good acceleration except ive noticed its dropped a little in this area. im topping out at about 127 last time i ran her. cant go past that speed breaker for some reason. ive had the bike to 160 just in october so its a recent problem but one none the less. ive been thinking its the valves but not for sure. can anyone give me a write up on here about how to clean the fuel injectors if that is needed. anything i can do myself i will. very mechanically inclined also have a ceritfied motorcycle mechanic in my club so help is not an issue. but he thinks im chasing a ghost when i know im not.
