Sometimes it won't start
I'm new to the forum. I have a 2008 Streetglide, I've had about 4 years now. It always starts in the mornings and after its set for an hour or so. It's hasn't failed to start after a while, yet. But sometimes, like when I stop for gas or to get a quick bite to eat, it won't start. It turns over, but won't start. Sometimes it will fire like it's going to. Sometimes I can turn it off and wait 30 seconds or so and then it will start, sometimes not. But if I let it set an hour or so it's always started so far. I'm puzzled. And as always, when I have it at the dealership it never fails to kick right off. HELP

Welcome to the forum. Your problem could be any one of a number of things: sticky exhaust valve, coils, ignition, vapor lock (gas cap too tight?), intake leak, etc. Can you figure out if it is a fuel problem or a spark problem? Sounds like something is not making contact when it is hot.

Of course... your problem could be a multitude of issues... but if I were you... I would start with the kiss method. While cold (since it starts cold)... start the bike and while running, pull the fuel pump fuse, remove the fuel quick disconnect and check for debris. Clean out with brake fluid up inside the qd adapter at the tank and the actual line... reconnect... replace fuel pump fuse.
Personally... I'd pull the CPS and clean out the orifice... and I'd do the same for the engine temperature sensor, and clean out the orifice and the sensor as well... reattach and I clean out the electrical connectors and use electric grease before re-installation.
I know not every sensor will come up in the diag mode... but have you pulled the codes (if any).

Have you tried varying the start procedure? Waiting for the fuel pump to finish priming when hot can cause problems, try an immediate start after turning on the ignition and see what happens. Try cracking the throttle open a bit. How fast does it crank? A hot engine has more compression for the starter to overcome. How old is the battery, have you checked the connections on the battery terminals for clean and tight? Have you ever checked the other end of each battery cable for the same, clean and tight?

I've noticed a slow start after fill up as well....albeit just once. i'll try the quick start next time, but will check the battery terminals first...might give the battery a slow charge as well...
