Valves - Riding when mal-adjusted.

I just did a valve job on my 2005 XR650R. 6 months ago, I got them spot on. Unfortunately, they tightened up a bit, so I loosened them, but I loosened them too much this time around. I'm now getting the annoying clanking from the loose valves.

I probably won't have time to re-adjust them until this weekend, but would like to ride tomorrow to work. Is this generally a bad idea with loose and loud valves?

I should probably stick with my own intuition that tells me just to let her sit until I get it right.

Always better too lose than tight. Too tight burns valves, thus leakage from warp or pitting.

What's that old saying? "A noisy valve is a happy valve"

Obviously the correct spec is the best thing but too loose is safer then too tight.

They're so quick to adjust, why not just make it right and ride. I had the same issue because I wanted to adjust them to the "safe side", but the extra clatter was too much. I redid it before the next ride and got it spot on and it's nice and QUIET now.

I adjusted my valves 3 times in the same day when I put a new cam in. The first time the moly lube got in the way and they were loose. The second time I was just retarded and they were loose. The third time I developed a technique for tightening the jam nut while maintaining the proper clearance and they are good now.
