When starting my 2015 RGS cold all is smooth but when it's hot it seems to hesitate before it engages completely.
Any ideas why??
Thanks

 

Put it on a battery tender overnight

 

Battery checks out fine and it's always on a battery tender.

 

I am experiencing the same thing. Sometimes it sounds like my battery is too weak to turn the engine over, and then it eventually starts up fine. I always have it on the battery tender and my battery checks out fine. It seems like the starter is dragging.

 

Exactly what I am experiencing. Going to have the dealer check it out since it is still under warranty. Was told it may be a compensator issue by an ex HD tech.

 

Same issue here on my 14. It left me stuck once. Pulled into a parking lot at night and adjusted my new headlight. Headlight was on without the bike running for maybe 5 minutes. It did tried to crank, then did that pause (like it always does), then wasn't enough to crank fast enough to fire.

 

From my local dealer/service writer, they are seeing two years or less on a battery replacement. It think if you check, your batteries are under warranty for 2 years from the date of sale.

Sure sounds like battery issues to me.

 

That's kinda what I've been leaning towards also. I just can't see why a battery can't last more than 2 years, especially here in ND where I can only ride 5-6 months out of the year. My bikes live in a heated garage and the tender makes its way to each bike. I have 4 bikes and two tenders. The battery in my deuce lasted 6 years. I may be buying an anti-gravity for my 14SGS before next riding season, hopefully that can solve this

 

I had the same problem with hot starts on a BMW I own. The problem was ultimately diagnosed as being increased resistance building up in the wire connecting from the battery to the starter when the engine was hot. As a result, enough current couldn't be delivered to the starter to cause it to spin up. The resistance reduces as the wire cools.

BMW issued a service bulletin that installed an additional wire (a second wire) between the battery and starter connections that enable more current to flow when hot. It wasn't a recall because all bikes weren't doing it, but the repair immediately solved the problem, and it has not re-appeared.

You might want to get a volt-meter and check the current being delivered to the starter during hot and cold starts. If you have a drop off on hot re-starts, it might be an easy fix for you too.

 

When my 2010 started doing it in 2013 new battery cured it
