I usually adjust my 04 RT valves my self. I had them done the last time I brought the bike in for some service. My question is, after an adjustment do the valves tend to get loose or tighter over time. Or is it sometimes looser or sometimes tighter. Why I'm asking is that after 5000 + miles all eight were still in tolerance, though a little on the tight side as to how I have adjusted them over the years. Thanks in advance for any help you can provide.
