Throttle Jerky At Low Revs ?

Looked at the casing and it looks like the previous owner snapped off or lost 2 of the 3 casing bolts  :'( Hope he hasn't mangled the 2 mounting bolts for the EXUP itself as they dont look too clever. I have sprayed them with lots of "Silkopen" and have left them overnight in the hope they will come off without too much drama. Hoping this will do the trick. Fingers crossed and wish me luck  :eek
