Thanks for the offer.

I apparently have a standard airbox top ont he way and have just been out and bought some 150 main jets (to try with modified air box lid), Once the bike is running to a reasonable level I will take it up to the dyno in aylesbury and get it set up properly. If its still not running right with the 150's I will put the standard lid back on and go back to the 128 and work from there.

If that fails then I may be on the blower to you go borrow the carbs...at least that way I can eliminate the jetting as the problem.
