Petcock leaking and won’t start.
#11
Sounds like the guy took out the diaphragm and spring in the petcock (effectively running the bike on prime the whole time) to bypass the vacuum line operating the petcock as designed. The other end of the hose should connect to a vacuum port under one of the Carbs (#3 carb on my 97). I was only able to get 60-65 miles a tank until I got a new petcock.

From that small hole comes out all the remaining gas in the lines from the carbs, after I turn off the engine.

Thanks for clarifying the leak. I was beyond tired when I replied so reading it again I see how and why I read the issue wrong.
Though I may add that I’m not sure at what position that ‘bleeder nipple’ as I call it needs to be in. I tried looking at the fiche diagrams to see if they show it but don’t. An when I look at pictures by part number (whether OEM or AM) I see them in the 12, 6, or 9 o’clock position. I imagine I could be in any one so as long as to bleed of any pressure (or vacuum) left in the line so the diaphragm can return to its neutral (or resting) position when not running.
Another on here may know better than me and please chime in if I’m wrong.
