I'm looking at a long list of topics to work on for future booklets, including one on how to adjust/modify panhead rocker boxes to compensate for wear, stem height changes, high-lift cams, etc.
This is probably very similar to Moto Guzzi, Royal Enfield 500 and a few other oddities, but not other H-D since the box height is not fixed in the casting.
Any interest? LMK.
No interest: goes to the back of the list.
