Anybody else tired of trying to problem this stupid bike with me? Geez, Louise, it just can't be this hard.
Okay, here's where I'm at:
Pulled the carbs yesterday, put in new fuel lines, checked all connections, semi-sync'd, etc.
Reinstalled airbox, wiring harness, etc., etc. ,etc. today, and decided that I'd go ahead and mount the tank and see if I could get fuel flow from the petcock. Last week, following someone's post, I pulled the spring from behind the diaphragm in the petcock, as well as the o-ring at the piston. So it's now a gravity-fed fuel system.
Charged the battery,turned the key, hit the starter, and got a nice loud backfire from the right side exhaust (front cyl). DEcided I'd better let O. catch fire in the driveway, so went out and hooked her up to the car battery. I continued to get occasional explosions (all but one form the right side), and once after a backfire - just once - the engine caught and turned over a little (and I had witnesses!).
However, I flooded the cyls periodically during this process, and finally gave up.
I'm guessing the backfiring was from trying to run it too rich? I pulled the plugs and they looked pretty dry, but all smelled of gasoline.
Anybody got anything else I could try to get this thing working? I am now completely out of options.
