Hey Guys, I've got a problem thats driving me nuts. If i leave the across sitting for say 3 days untouched (fuel tap off or on doesn't matter), when i go to start the bike it won't fire at all because of no fuel. You hear the pump prime for a say 2 or 3 pumps then it stops, but still no fuel in the carbies. The only reason i know its an air lock is i used to have an inline filter after the pump going to the carbs and i could see it empty and the pump wouldn't prime anymore. Anyway i found today that after a few turns of prime pump, key off wait 2-3 mins, then repeat. After about 10 mins i managed to just have enough fuel in the bowls to start. Once started and i could rev it, it cleared up and the bike is fine. I've tried 3 different fuel pumps, the carbies have been cleaned and have got new pilot jets and clear main jets, the diaphragms are good as well as the sliders. I haven't changed the needles and seats yet. Any ideas ????
