Are the 2012 to 2013 specs the same — intake range 0.10–0.15mm, exhaust 0.12–0.17mm? I ask because I found my 2013 intakes a bit outside that spec at 8 hours.
I popped the cover thinking just to familiarize myself with things while it's still mostly clean and found a 0.10mm feeler very tight on the intakes. I replaced the 2.85 shims there with 2.80mm shims and now it seems right: 0.13mm is a snug fit, 0.15 won't fit.
BTW, valve adjustments are sure simple on these. Very nice.
