Can you tell if you have already had stainless valves fitted without taking the head off

good question...and i'm not sure. i've never laid the side by side to analyze the visual differences.

sorry i wasn't any help. at least my reply will bump it up so hopefully someone else will see it.

The only clue I can think of isn't really the valves... but if you look at the spings and see they're springs-within-a-spring design, that's the Kibblewhite springs... I'm not sure why someone would shell out money for expensive springs like those, and put Ti valves in.

I'm guessing you bought your bike pre-owned, or maybe 3rd owner now? Any way to contact the original owner (I know,, it's the obvious question... sorry)

that's a good point. if they don't have the kibblewhite springs it really doesn't matter if they are stainless steel valves or not. in fact, if the springs are kw then hope that the valves are stock ti valves.

I don't believe titanium is magnetic. Stainless steel is magnetic (unless it is austenitic grade). If you have a magnet on a stick (available at auto parts stores and hardware stores all over) you can try to stick the magnet to the valve (through the hole). This is a pretty weak method of testing. I personally think it is highly unlikely that the valves in your engine are stainless. For the cost of the valves and the trouble it is to get them out, you might as well order some up and do the job right all at once.

Good luck.
