...what darkhorse said.
like I said you will probably only do this on higher mileage motors. I personally have never heard of anyone doing this to a motorcycle, although I'm sure it can be done. also with today's fuel injection setups and direct injection and various control modules and sensors that monitor the A/F ratio to make sure as little fuel as possible is wasted, excessive carbon really shouldn't be too much of a problem unless it's been abused or hasn't been maintained properly.
