Have you removed the cylinder head? How many miles has the odometer recorded? How old is the bike?

Personally, I would remove the valves and inspect them for bent valve stems. I would also lap the valves, and replace the valve stem seals. However, if you are uncomfortable performing these tasks, and the bike is low mileage, I can understand why you might prefer to leave things as they are, especially if the valves are passing the "solvent test."
