Bought a very neglected 2000 bird this year. First thing I did was to change plugs and change oil,filters. The air filter was completely clogged, I do not know how it even ran! Since then I have put in a R/R ,battery and a new CCT. I noticed it was low in power and had poor throttle response.
So today I filled her up with high test and allowed her to spread it's wings. At first she struggled to get 7500 RPM, the when it did it cut out. I kept trying to get above 8000 RPM until it would hold. It has cleared up and does not cut out but will only go 105 MPH at 8000 rpm in 6th gear. I am thinking it needs a valve adjustment. Any advice would help thanks.
