hi can any one help me ajust the valves on my 1981 xs650 witch side do i start on and any help will be great i was told it is not hard i an 72 years old and i do all my own tune ups but i forget thanks pop.
Remove both spark plugs. Remove all 4 valve inspection covers. Remove the Generator cover (L crankcase cover, round, 2 screws). It doesn't matter which side you start on. Turn the crankshaft in the direction the engine runs. Depending on which cylinder you're working on, watch that intake valve. When the rocker arm pushes it down, then comes back up, the piston is then moving up on the compression stroke. Continue turning until the piston is at top dead center. You can line up the T mark on the flywheel with the pointer, or look into the spark plug hole to see when the piston is at the top. Adjust the valve clearance for the intake exhaust valves on that cylinder. Repeat for the 2nd cylinder.
It is complicated, you need a special tool and the shims to do it correctly. They don't adjust like the other bikes.....
