Occasional knock at idle after engine is warm and idles for a period of time, say at a stoplight in traffic. Does not do it all the time. Dealer said it is carbon in the cylinders. Cleaned with spray cleaner while running, went away for a while. Then came back. Noise is in both cylinders, only at idle.
2006 Kawasaki Vulcan 900 Classic has occaional knock at idle.?
