nice of you to be so considerate, but in view of how many posts i've gotten about owner's group names and dickheads, i think everyone can put up with post that's actually in line with the purpose of this list. if i were you, i would replace all your shims. from memory, it seems like your exhaust valves are either out of spec (left) or right on the border (right) (isn't the exhaust spec .006-.010?). i figure that as long as you have it apart, you may as well do em all. otherwise you'll be worrying about the ones that are close until you get in there next time. the valves certainly do get tighter over due to valve and seat wear. the valve gradually sits higher and higher into the seat, so the other end of the valve pushes against the shim which gets closer and closer to the cam. all my valves (on a y2k model) closed up about .002 over the first 6k miles, so i shimmed them all to the loose side of spec. i'm up to 12.5k now, and due any day to check them again. i'm pretty confident it will be only a check, since they were fairly loose before, but you never know. note: don't forget to recheck the clearances with the new shims. 2 of mine were exactly what i calculated, but 2 of them were .001 tigher than i calculated, which was still fine, but i recorded the actual measurements afterwards so as to get an idea of the wear rates from 6-12k. mw

My favorite bike of all time was my '85 FJ1100. Bought it in 1992 with 7k miles, a bank repo. Put 30k on it and sold it in a moment of weakness in 1996. Then this spring, I found an '85 for sale, advertised "like showroom, 4500 miles." Turns out it had 4200 and WAS like showroom. It is now setting under a cover in my garage with battery tender attached. Will probably never part with this one.
