Any experts out there? 6k miles seems a fairly short service interval for a shimmed engine these days. Old 911's would easily go for 12K (and actually a lot longer before reshimming required). Some modern bikes seem to go for tens of thousands of miles before reshimming. Whats going on? Is the shim material relevant?
Maybe I got the wrong end of the stick. If its simply a tappet adjustment why so long (service time)?
I have had old 911's which did require the shims measured to reset clearances, not the same thing at all then.
Still seems pretty short 6K.
Shimming (maybe not correct term), to use variable thickness (i.e thinner) shims to modify valve clearances. Rather than some tappet adjuster.

Changing oil at 6000 certainly a good idea with mineral/semi-synthetics. Debateable if really necessary with modern synthetics (I think Mobil 1 advert claimes up to 20,000, not that I would leave it in that long in any car let alone a high performance one)
