First off, the jerking problem seems to of gone......noticed it was only doing it when I had less than 1/4 tank. So put some fuel system cleaner in and brimmed the tank. Used 1/2 a tank so far, and all good through the rev range so far. Fingers crossed.

Also brought a second hand gear knob (Cheers Steve (1-PD) with really good leather. But the polished finish was going grubby to quick. So sanded down with the drill, coloured the numbers dark blue and about 4-5 coats of clear acrylic metal lacquer.

Ready to go back in the car, but going to get some new gaiters first.
