Lumberjack I am adjusting my valves because mine got to making a racket. I tried the service manual method when it was at 16000 miles and they didn't need adjusting. Now I am at almost 30000 and they are making noise. I talked with my wrench the only guy I trust that owens Metric Tech bike shop. He said the way to adjust them is bring it so the valves are open and let the lifters bleed down then bring it to TDC loosen the nut on the adjuster and loosen the adjuster. Push down on the slip side of the rocker arm holding it against the valve. Run the adjuster down on the other valve until it is against the valve and tighten the lock nut. This is considered 0-lash and you can't go wrong. Do the same thing for all the valves. The manual says 0.04mm or 0.0016in which might as well be zero lash when the engine heats up.
