Road King hard to start
 

I was on a 200 mile round trip this weekend when my 05 Road King did not want to start after I stopped for a cold one. The engine would barely turn over but finally cranked. It was about 95* and I had been running about 75 all the way. After I reached my destination and let the engine become cold it cranked with no problem.

What do you think starter or battery getting tired and need replacing or just a long hot ride.

Battery

+1 on the Battery (take to Autozone or Advance to check).
