That's all cool, except that the spec for intakes is .10-.15mm. Typo?

Yes, that was a typo but my manual shows .15mm - .20mm as the intake spec. Thanks for the catch and also for all the help you've provided on the forum over the years.

2000 with SS valves, then, right?

Yup, 2000 and I'm assuming the valves are probably SS. All the intakes were replaced right after I bought the bike (used) a failure caused the piston and valves to get more acquainted with each other than they should have. That's a whole other rebuild story.
