"Valve Clearance" refers to the small gap between the valve lifter and the valve stem that allows the valve to completely close. Remove the Valve Cover and set the crankshaft to the timing marks (only found in your service manual), for each particular valve to be completely closed. Loosen lock nut and set with a feeler guage then retighten the locking nut on the adjustment shaft. Four valves = four adjustments. Does this help?

Adjusting the valves depends on the engine setup. I am going to use just a generic type. Clearence is a mesurment between the end or the stem of a valve and the cam or lever that actuates that valve. Lets say .012 inch is ruff the thickness of a match book cover (not exactly but example) Your spects say that much clearence is needed on the exhaust valve, then once it is adjusted the match book cover should slide in and feel some risistance going in & out. Now, I just looked up your cycle if it is the one I found, that is a cool bike. You have a push rod engine I believe. Looking at the pictures. You will have a fulcrum lever type of valve set up. A rod pushes the lever up on one side to push the valve down on the other. You measure your clearence here on top of the valve and adjust it on the other end with a screw and lock nut. loosen the lock nut and screw the adjustment screw (up, down) till the disired clearence is met. The easy way is to watch both valves one side is the intake one closest to the carb. the exhaust is closest to the exhaust pipe. Turn the engine by hand (remove the spark plug for easier tuning). watch the valves one will go down and adjust the other one then do the opposite for the ohter valve. if you see the valves rocking (meaning one going up the other going down at the same time) keep turning till one moves without the other. I hope this helps you. work slow, ride careful.

you use a set of feeler guages to measure the gap between the valve and the tappet (the arm that opens the valve) there is a intake and exhaust gap setting. you'll have to do some research to find out what the gap should be for your motor.

The valve lash adjustments on these bikes are done with shims on a COLD engine.
Intake valves 0.15-0.20
Exhaust valves 0.22-.0.27
Check the specs on your emissions sticker to confirm...California bikes are subject to change.
If you are not familiar with timing marks and adjustment procedures, i recommend you buy the manual and follow the steps outlined, the illustrations are also a big help.
Good luck, i hope this helps.
