I just got my bike out for the season first ride of the year when my day was cut short because my engine cover plug (92066-0039 PLUG,12X9.1 ) fell out at some point during my ride and got oil everywhere. Now this happened to me last year as well so i just ordered a new OEM plug and thought that would fix my problem. Clearly it did not. The threads on the cover do not look stripped. What do you recommend? Is it okay to use locktite on the plug?
