How to: Valve-stem carbon removal?

But I've also heard that transmission fluid will do it too, but I wouldn't recommend it on a motorcycle engine. I'd be worried about scoring the cylinder walls.
But since you can actually look in your exhaust ports and see the valves, I don't see where it would hurt anything to paint some tranny fluid directly on the carbon deposits. Maybe it'll soften it up and blow out next time you run it.

Just don't run the engine with the headers off...

I doubt water will clean the carbon off valves where it is baked on and thick. One of the gas station companies sells gas with a chemical called Techron which is made to remove this stuff. You can buy bottles of the stuff to use in higher concentration but I doubt it will remove burned on carbon. I think a wire brush wheel on a drill or Dremel tool would be the best bet. If the stuff has crept up high enough, the stem seals will be toast. I would buy a new cylinder head gasket and remove the head and do some cleaning and have some new seals on hand.
