Just did mine and it did the same thing so i looked at it more and what i did was when you first turn the key it fully closes the valve then fully opens it! i pulled the plugs when it was fully closed
and it would not go over 6500 to 7000 but now i got it right bike is louder, smother throttle, pulls a little harder
