Cruisin' Guzzisti
I'm sorry to ask such a basic question, but I only do this once a year or so, and my notes are confusing me.
I can't find specs in the owner's manual.
Guzziology basically says all big twins are In: 0.004" in. (0.10mm) / Ex: 0.006" (0.15mm) if you're following world specs.
The PDF Workshop manual (in English) agrees (which makes me wonder if it was meant for the US or just an English translation of the world spec guide).
And I'd have followed those specs (as I do on my Jackal), if I hadn't found a note on my service sheets that I wrote which claims the EPA label (which I can't find right now, was it on the seat?) said THOSE figures were the tighter US spec, and that there are looser world specs of In: 0.0059" (0.15mm) / Ex: 0.0078" (0.20mm).
My notes seem REALLY specific with the measurements.
I was going to ignore them and follow Guzziology and the PDF manual, until I measured the first intake valve and realized it was set way too loose for the 004" spec, which got me thinking maybe I followed the 0.006" spec.
What do you guys use?
Any idea where I pulled those other specs from?

PS - didn't there used to be a detailed valve adjustment thread here, I searched a couple of times but couldn't find it.
