Went to adjust the valves the other day and when I went to loosen the lock nut on one of them it snapped right off with very little effort. Wow, good thing that didn't happen when I was riding! Has anybody else ever had this happen on anything? I did some searching on the web and found a few stories like this on other engines.
Of course this meant taking the cylinder head cover off to replace it. The adjusters I used (CB Performance) came in a pack of 8 so I replaced all 4. Seriously considered going back to the stock units but the elephant foot ones are so much better, and they has seen plenty of adjustments in 41,000 miles I figured it was save to use them again. Besides that I don't know if I have 4 good stock ones because they have lots of mile on them.
So I wondered, I never use a torque wrench to do this but this time I did. Wow, 20 foot pounds is tight. I doubt I ever tightened them this much with a box wrench. Out of curiosity I looked up the spec on a Porsche (that's what the adjusters were made for) and it was 20 foot pounds too.
