Your pic is a bit small...and making it larger just pixelates the heck out of it. How does it compare to the following?
I've attached a shot from RR, about which he says:
"The plug INSULATORS look dramatically different but the jetting is pretty much spot-on in both cases."
(the second plug he's referring to obviously not shown in this thread. Go
HERE to see the whole story.
The band on your plug looks a bit wide to me.
Compare the two plugs and see what you think. As RR says: "It's worth the effort but I can tell you after peering at plugs for 30 or so years I still have more questions than answers most days."
Anecdotally, (and therefore mostly useless) I am running 40-152-CEK/4-#7TV, but that's with the KG-30! That pipe takes a considerably
richer jetset than the KG-35 does. That setup is good to about 50º, 2000-4500'el.
Point is, besides the band looking wide (that's what you're after...the width of the band at the bottom of the insulator), I'd
WAG from your jet list that you're still rich some.
