Exactly as I suspected, the 8000-mile service revealed no dents in the Honda’s anvil-like personality. After removing the radiator—not a difficult task, actually—getting to the valves for a clearance check took all of half an hour, one positive aspect of the NC’s laydown engine. All four exhaust valves were tight by 0.001 in. (The spec is 0.011 in. plus or minus 0.001 in.) I know most guys wouldn’t bother to make the adjustment, but I’m a bit anal and it’s a screw-and-locknut system after all. One of the four intake valves was slightly tight—though technically in spec—but the other three were right on spec, so I brought the fourth in line.
