Re: starter motor on an 1984 1200A
Mine did that alot when I had 20-50 in the engine. Sounds like yours is just cold thick oil. It will cause the starter clutch to be slow in doing its duty. Its possible too that you're starting to get a little sludge build up in the engine. This will affect the clutch the same way. Come next oil change, dump some Marvel Mystery Oil in the crankcase and take a good ride, then do the oil change. This will usualy correct that problem.

Sometimes synthetic (motorcycle) oil which can maintain the thinner viscosity at lower temperatures can help as well. MMO or Seafoam is a good preventative measure, however.
