Hard starting 110
« on: April 19, 2021, 07:59:27 PM »

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.   :confused5:

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.

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)
