So, just started 2 weeks ago and its happened enough times for me to fashion a pattern of sorts. The bike starts and runs fine (aside from being terribly cold-blooded but thats happened since we got it) but if I turn it off and run into the store for 15 minutes or so, it won't start when I come back out and sounds/smells flooded. It'll start 45 mins-an hour and a half after though. It also starts right up if I take it to work and leave it for 4-8 hours. Its just if I leave it for <an hour.

Tried turning the petcock off while its sitting, no effect. Tried starting it wide open throttle, but it still won't grab. I was theorizing that the float might have been running heavy and seeping fuel into the chamber, but from what I understand harley runs vacuum fuel lines, and turning the petcock off should have stopped any fuel from leaking.

I only had 1 successful hot start and it was when I popped the choke out a bit right after I turned the bike off, then popped it back in a couple seconds later. It started when i came out of the store, but honestly it could have been a fluke, i'm not sure what effect that could have had, if any.

Bike is stock except for a few cosmetic changes.

In any case, any help is appreciated.

Nothing comes to mind for me and I probably should even be post on this but I would check a couple of things I list below just because if it were me I'd have to start somewhere. But the extra info might help someone who has more experience than I to help you.

How do your plugs look? (may indicate flooding condition)

What rpm do you usually set the idle at? (if it's very low I think it will make a hot start more difficult)

Is your air filter clean? (I think a severely clogged filter starving the engine of intake air will have same effect as flooding from too much gas)

I think there is an overflow line out of the carb, is it dripping when you say you smell gas?

You should always turn off the petcock when you stop anywhere.

Fuel vent ??? The vent can cause pressure as well as vacuum depending on the circumstance

Turn the gas off when you stop and turn it back on when you want to restart !!!
