Post by motorboy3 » Sat Aug 05, 2017 5:45 pm

Any Idea's My bomber starts and idles great but when i take it out for a run and stop at a red light or the like the revs drop to 500rpm and it cuts out(engine stalls)? Also does any one know what are standard numbers for the pilot and slow jet UK bike

You might have a problem with a vacuum forming in the tank.

Does the bike start right up afterwards?

Have you tried adjusting the throttle stops?
