Re: Valve grinding on an sv650
Seems odd that all eight are leaky, is there a position the engine could be in where all of them are open to cause corrosion as you've found?
Anyway, although I've never needed to do so on any SV motor I've attended to, even very high mileage ones, as far as I know there's no reason why you shouldn't lap the valves if they don't seal right, although if it were mine I'd examine the seats carefully to see if cutting rather than lapping would be a better bet.
PS. You sure you haven't got bent valves or if there's corrosion on the stems causing them to jam up on the guide? I've seen that on a motor that was unused for some time.
