[QUOTE="Bill Cannon, post: 125682, member: 152"] Well, the plot thickens. Had to go to work to get the valve spring compressor from my "metric" toolkit. Now removed the valves and guess what? No stem seals at all and apparently no facility for fitting them (see photo). Does anyone know better? Valve seats look OK the exhaust seat was a bit dark but appears flat and ground easily with a quick zip of fine paste. Inlet seat is clean but a lot of carbon on the intake side of the valve head (see photo). By feel, there's no detectable play in the guides. I've only done the rear head at the moment, I'll strip the front this afternoon. It seems I won't have much choice but to put it back together and see how we go. Maybe I need to open an account with Honda for the combustion chamber cleaner! Cheers Bill [/QUOTE]
