I'm putting together an order of items to do my own tune up. As my bike is my commuter, I would like to have shims on hand in case I need to adjust the valves. I'm not a mechanic, but understand mechanical systems. I'll be doing this at a mechanic-friend's house, so I'll have the right tools available (feeler gauges, etc.). Which measurement in the manual do I look at for deciding which size shim kit to order? Valve head diameter, valve bucket bore diameter, valve bucket diameter? Thanks!
