Time to change the spark plugs. Gap them at .018" ad use the ones with solid terminals on top. Don't let it idle too long during warm up. Jab the throttle once in a while to clean out excessive fuel accumulation in the bottom end.

Mine did the same thing when it was new. Don't remember the exact details but there was an update, check with your dealer. I think it was a timing issue.
