To my partially trained eyes, I honestly couldn't tell if any oil was leaking past the two seals. The two valves with worn guides were coated with LOTS of carbon build up, but it was obvious a lot of oil was going past the rings, and not so obvious if any got past the seals.

Suzuki's method for checking the the wear of the valve guides/valve stems is to lift the valve off the seat about 1 cm, then to check with a dial indicator the amount of play in four directions. Up to .014 is allowed. Then by measuring the valve stem you can determine which needs to be replaced.

My valve stems had no measurable wear. All guides excepting the two front exhaust measured about .008-.009 with the dial indicator. The two bad ones were .015-.018 which was very noticable.

I did get replacement cam chain guides and tensioners along with chains. They all came off a very low mile 2007 SV650 that was salvaged.
