30,000 miles and didn't need any adjustment!

I checked my valves early because I thought it was a bit noisy, and at 8000 miles the exhaust valves were 0.13 and the inlets 0.21, all on the loose side, particularly the inlets. Almost certainly set loose from new, and I've heard others report similar. I wasn't overly worried, I'd rather have a loose valve than a tight one anyday. Nevertheless, I set them to 0.12 inlet and 0.18 exhaust.
I always note down the measured clearances in the service book. At 12K, they were the same (as you'd expect). At 20K, they still measured the same, possibly a slightly tighter slide on the feeler gauge. The last time I did them (31K), they were 0.11 and 0.18 and I left them alone again. So you can see that they don't close up much in over 30K miles, and at that rate, if I'd left them as they were out the factory, the bike would be good for 120K miles before the valves reached the lower limit of clearance!
"If it ain't broke - don't fix it" is a good phrase to quote when it comes to valves particularly. I'd say check them at the required intervals; 'check' being the operative word. Don't feel compelled to adjust them unless you need to: if they're out of spec, or if they are getting close to the lower limit and you didn't think they'd last till the next check.
