[QUOTE="Jejochem, post: 574914, member: 18886"] I've twin 40 Dells on 2007cc and never felt it was running right. I changed the mechanical pump for a CB Performance rotary pump. This has a regulator and filter built in and is set at 3.5psi which is the ideal pressure for the Dells. The difference was amazing. Much smoother throughout the Rev range especially at lower revs. Starting is easier as well, a few pumps of the throttle before and it fires instantly. Your original pump maybe worn or the pushrod sticking when warm after a run. Plenty info on both cb pump and mech pump sticking if you try a Google search. I've got a 009 dizzy, may well change this for a vac advance after reading about them. Good luck, Frank. [/QUOTE]
