I just removed the carbs from my '01 SV650S for the first time and was surprised at how much carbon build up is on the backs of the inlet valve heads. The ports are clean and so are the valve stems, just the valve heads are carboned up.
The bike runs great and doesn't burn oil, but there is more crap on the valves than I'm used to seeing on my old BSA's.
Anybody else noticed this?
