Check the spark plugs, see if they are tight. You might as well change them so you know the status. It's an easy job, you just need to remove the rear wheels and remove the fender liner. Think about replacing the spark plug tubes and the spark plug tube "O" ring seals too. There should be allot of info on this task on the forum, just do a search.

Also check the exhaust for leaks, check all the bolts and see if any are missing or loose, especially the headers.
