Try some Sea Foam or other injector cleaner.

Try some Sea Foam or other injector cleaner.

I put a dose in about 600 miles ago. Waiting the specified time to put another dose. At a stop is the only time I notice the rough idle. When riding I don't feel it. Thanks for the reply.

I would go ahead and add a maintenance dose of Seafoam. It doesn't hurt to use it more frequently, it can only help. I use it every 4 tankfulls or so, and I go through at least a tank a week.

I'm not sure fuel is the root of your problem, but it can't hurt to try.

Here's their video on how often to use it, depending on how quickly you use up a tank of fuel.

Hope this helps!

On my 12, the rough idle was the first sign of cracked map sensor hoses. After replacing them all is good.

On my '13, my battery was coming to the end of its useful life and when I put in a new unit, the idle settled down.
