not gonna pull my records for actual mileage,,
but a couple years ago, I was prepping for a road trip and did the valve check as part of the service. No change,,(around 30,000 or so),,everything right in the middle of tolerance!,
,Rode for another year or so,,another long trip coming up,,better check,,dead within the middle of specs.
14,500 miles later,,checked again,, still within tolerances,,no adjustment needed.
I just rolled over 50,000 miles on the engine, and I wonder if I should ever bother to check the valves again,, the last 3 attempts were for nothing!
