I think you will need a main jet and a pilot jet.

Robin, my gripper is also a 250 but it has a MAR piston (2mm extra) so i think its 244cc i also put the window in the back of the piston. I put the mikuni on because i wanted the revs to pickup quicker, i have also reduced the flywheel weight on the cush drive, then also drilled some big holes in the clutch basket. I feel if i go anymore i will loose its grip low down the revs.
steve.
