OK, now that the forum is back up and running I can vent...and I'm sure some here will relate. I tried starting my Nighthawk 650 last week...drained the battery trying to get it to start. Recharged battery and tried again later that day....same thing...battery drained, no start.
Recharged battery overnight. Tried again next day. No start. I thought it must be fuel related...so opened drain screws on float bowls..nothing coming out. Ah ha! must be petcock related! Removed (full) fuel tank...set on ground. Sucked on little vacuum hose going to petcock...no fuel came out..looked silly doing it, too... then thought, why don't I check the petcock in all positions?
Turned petcock to what I thought was 'off', sucked on vacuum hose and fuel came right out...Defective petcock? Nope...dumb me confused the 'on' and 'off' positions. Aaarrrrggggghhhhh!
Reinstalled fuel tank, turned 'on' petcock, bike fired right up. Damn petcock.
