June 29, 20251 yr I have a 2016 Evo with the electronic petcock. I am getting no flow when turning the manual override lever. When I try kicking nothing dribbles out either. I need to pull the petcock to investigate. Is there another way to get the petcock open so I can drain the tank? I could try a hand pump to siphon out the gas but suspect there will still be a lot of gas flowing out when I remove the mounting bolt. Is there a cleanish way to do this? The odd thing is that the initial symptom was hard starting when cold or hot. The bike ran fine once started but I did start to get occasional odd noises in the exhaust. I adjusted the valves and cleaned the carb but when trying to start discovered this no flow issue.

You could try removing what gas you can from the tank then elevate the rear of the bike so any remaining fuel moves away from the tap outlet. Did you try to drain fuel with the tank cap removed?

July 1, 20251 yr Author I used a hand pump to pull the gas out. When leaning left on the stand some gas leaked when removing the petcock but not a large amount. I was then able to lean it right to get most of the gas into a funnel. The back part of the little black plastic lever had broken so was non functional. The parts list just shows the entire petcock assembly which is not cheap. Is the little lever available somewhere, maybe in a rebuild kit? This would be a really annoying failure mode to happen if you show up to a trial and need to manually get gas to the carb.
