So I'm at my 12K service (more like 12.8K

), and I finished measuring my valve lash. Just pulled off the tappets and have the shims ready to measure, but need to grab a different measurement tool, since mine only does 0.1mm increments.

EX (mm)
1 0.23
2 0.20
3 0.22
4 0.28

IN (mm)
5 0.21
6 0.20
7 0.18
8 0.20

So 3 of my exhaust valves are tight, with only 1 out of spec. My intake valves are pretty close to the midrange of the spec.

I'll need to adjust the exhaust valves for sure, while the intakes could technically be left alone. However, I am debating adjusting them anyway to 0.195 mm, just because I have everything open now, and it'd be nice to balance them.
