How many follow the instructions on page 3-10 of the Honda Service Manual when checking valve clearance? I'll get different measurements when I adjust valves with its opposite valves fully open, thus the lobes of the valves I'm checking are 180 degrees away from the shims than if I follow the service manual sequence where some lobes aren't 180 away from shims. I find that when I follow the sequence in the service manual and then re-check individually (with lobes 180 from shim) I have to re-shim 90-95% of the time to get back within spec.
Want to do the valves in Dannys bike tomorrow, lower engine to get carbs off then crank to check compression. Want to keep as much carb 'crud' out of the engine as possible and disturb carbs internals as little as possible until ready to take them apart.
