Hey guys, I finally broke down and adjusted the valves on my '98 with 5K miles on it (because I had to take the tank off anyway to tighten a leaking/loose rocker shaft cover cap next to the RFVC logo). I had it done once by a dealer here in San Diego when I first bought it (used) with about 2.2K miles on it back in September of '03. When I checked the clearances they were all out of spec and the intakes were noticably tight, and this is only after 3K miles of DS riding with mostly street miles, but with some hard off-road ones, too. I'm not sure how loose or tight the dealer set them so that is an unknown. I'm hoping they were set right. My questions are how often do you guys check the valves, and do the intakes usually get tighter, even after so few (3K) miles? I use Mobil 1 15W-50 red cap full synthetic oil and change it often. The bike runs strong with no problems at all. Thanks & Happy New Year to all the Thumper Pilots.
