FZR jetting

Wasn't completely happy with the jetting. The top end was really buzzy, lots of vibration, and the low end a bit lurchy. So I decided to go up on the main jets 120's and turn in the air screws by half a turn. This done, I am also concerned about this bikes white lining. It is just crap, so looked at the alignment of the wheels which seemed OK, and the next choice was to look at the spongy fork, I removed the gold valves and adjusted them to have 4 threads showing. There was some funny stuff bunging up one of the valves so I cleaned that all out but have no idea what it could be.....
