I have 2010 FLHXSE. When starting up cold first thing, no issues. Fires right up. If turned off for about 15 minutes, no re-start issues. However, if after riding for a while and stop for an hour or so, hard starting. Fuel pump primes and motor turns over fine, but doesn't fire up. After a few tries starts up and runs fine. Any ideas what's going on here?

What is the miles on the bike?
Have you tried new spark plugs?
Fuel pressure test or check for codes?
Hot crank senor breakdown maybe.

Following.....I've been dealing with this for two/three years. Rarely an issue, only when stopping for fuel or short stops after getting to temp. Changed starter clutch at stealerships suggestion, but still there. Changed fuel caps, no change.

About 73K miles. Plugs replaced per maintenance schedule. Taking into dealer to change fuel filter and will have checked out at that time.

Thx!

Automatic compression releases?  I just had to replace one on my 16.

Does the motor seem to struggle to spin when starting hot?

You didn't say  if this issue began not long after your maintenance of changing the plugs It could very well be the plugs.
I've had new plugs that fail when they've gotten hot before.  I'd try changing the plugs again before letting the Stealership go on an expensive witchhunt.

You said it's fine on starting up when cold and warm but not when hot. Fuel filter wouldn't distinguish it between it being hot or cold the plugs would.
It's the same as a plug will work fine on normal running but will fail on high acceleration (miss fire motor hesitation etc.)

They may not be your issue but on a two banger motor it only takes one to give grief.  For what they're worth my money's on the plug if this started not long after changing them.

Mine did similar, thought it might be battery as it was 13 years old. It was the compensater in the end of the crank.

I've had a similar issue with the compensator.

[FELIX]

I had the exact same thing on my 110.  It turned out one time to be the compensator, needed to be beefed up to the screaming eagle one.  Harley should have just put these in on any 110.  I also had a compression release that stopped working, fairly easy to test and diagnose.   When you stop after a long ride and try to start it does it sound like crap, lots of noise coming from the primary (embarrassing) as it struggles to kick over?  (Yes=Compensator)

My 14 CVO RK does this PIA thing when refueling hot. Live in FL so hot is the norm. So about every 10-15 times after a refuel it goes into a limp mode and the check engine light appears. 70% of the time only requires an ignition switch recycle. But 20% it keeps going into that same mode even after several attempts and differing periods of time between attempts. Otherwise a strong running Stage 2 110.

Sorry....Just realized how old this thread was. I'm old too though!!


I agree with most recommendations so far especially the compensator if it hasn't been changed. Also you would be surprised at how dirty a fuel filter can get at only 25000 miles. I'm not saying this is the issue but it hasn't been changed, change it!

 I had the exact issue with my 2010 FLHXSE. Dealer couldn't find any issues. Battery started to show signs of age so I replaced and no more starting issues! Whoda thunk?

The CVO 110 cranks 225lb without compression releases, stock. The ACR exhaust passages get blocked with carbon over time. This can be serviced with the heads on. I am assuming slow cranking. Thr ACRs are very robust parts.

Mine has been doing this for about 8 years. Only does it when hot. Have changed plugs many times, fuel caps many times, and like I said also the starter clutch. Very annoying. Will look into compression releases as it turns over and sounds normal, just won't start. Give it a minute (or 10) and it always fires back up. Will look into compensator I suppose.

Cheers
