Default Re: Valve grinding on an sv650

well!!! when you turn it over by hand with the engine sitting on the bench, I can here air escaping up the intake and exhust ports, also sprayed wd40 down and can see them bubbling. its def the valves.

yes checked valve tolerances, actually took cams off and turned it over whilst holding chains out and it still happens. its the valve seats.
