Re: Valve Clearance Question
I think you are right that there is an overabundance of caution when it comes to these things and BMW service schedules in general. In another parallel thread, Voyager reported back that after many miles running too tight intake valves at 0.10 mm, it is no worse for wear. My worst valve is 0.13 mm, or only 0.02 mm under spec. It's the intake side - I doubt burning those valves is a real risk. I am also again questioning the logic of needing to run at higher clearances than minimum specified. In range is in range. I also hear that the wear rate is extremely low, so why go to the loose end?
That was the one little bird talking in one ear but the other one prevailed. I went through the exercise to also document what I have for future reference. Mine is a low mileage LT (hope to put tons of miles on it when I can quit working and get more time) and wanted to nip any possible issues in the bud to get maximum life out of this thing.
I like to tinker and now am confident I can do this work without a big deal. If I don't come up with a 2.90 bucket now, I'll button it back up and order one for next service. I don't have the luxury of a dealer nearby to pop in and buy one. I hate to see my bike torn down when I want to ride!
Thanks for your opinion and view. That's what makes this forum great.

Reason: It was Voyager, not Curtis running tight intake valves
