XS400 1979 stop sign problem

[big_dave]

I have a XS400 1979 twin.

What the problem is, is that when I come to a stop sign the engine kills. I have replaced the needle and seats, and the intake rubbers are NEW also. I set the air screws to the specs in my manual, the airboxes have good foam, nothing plugged there. One guy told me it might be the diaphrams in the carbs, MUCHO money for those things. Could it be the diaphram in the petcock? Any info would be appreciated.

Thanks in advance... Big_Dave

Are the pilot jet passageways and/or pilot jets clogged? You can always check your spark plug color right after it dies. Also, have you performed a carb sync?

Does it only happen at stop signs (when you stop the bike) or will it idle normally otherwise?

Actually it is my sisters bike, she lives in Michigan. I told her to have the carbs synced, I did clean the pilot jets very well when I did her carbs. They could have clogged again though. I will ask her about the idle.

Thanks Big_Dave
