Yeah, it's a bit of work to go through the valves but you're really gonna like how this engine responds to proper valve clearances. It's worth the effort. With regard to your thought about the bike only having 25K miles on it, I got similar valve measurements (tightness) on my '99 which only had 19K miles when I purchased it. I think there it's normal for the cylinder head to experience a pretty good bit of "valve movement" at that mileage. I understand that after the first valve adjustment (at a mileage similar to our bikes) the "movement" of the metal in the cylinder head valve seas slows to almost nothing. My second 5th Gen VFR, the '01, is a very low-miles bike, with only a bit over 12K miles when I purchased it. Even with that low mileage I still went ahead with a valve clearance check/adjustment on bike. The exhaust valves were all within specification but on the intake side 6 out of 8 valves were tight or close-to-tight. I don't know what it says about my personality, but I actually enjoy doing valve clearance checks/adjustments.
