There are no jam nuts on the stock setup. I think that the original factory idea was to have an interference fit between the adjuster and the rocker threads. The thread is 3/8-24. I have some thin 3/8-24 hex nuts. Do I need to have the rockers spot faced before using the hex nuts as jam nuts? I am concerned about the nuts actually coming loose and coming off of the adjuster screw. Any other suggestions to maintain the rocker adjustment?
