Pull the tank off of the bike (keeping the vacuum line connected to the petcock) and open the valve, it should not flow any fuel, maybe a few drips.

Suck on the vacuum line gently (without inhaling, just pull air into your cheeks or you'll fall over and have a nasty headache) and it should flow a steady stream of fuel from the petcock outlet.

That's the best way to test the petcock, but instead of sucking on the vacuum line you can connect a longer hose to the #1 cylinder and test the flow with the tank on a bench by cranking the engine over with it connected.

 

Will try ....

 

jk lol....take it off and use compressed air

 

Well after 3 sets of carbs, resistance checks on coils, stator, pulse , still the same thing..

Start really looking the bike over and found a broken wire on kickstand switch, fixed it and it ran like a funking champ!!


WOO HOO>>>
