    Lean = hot. A good eye can read the plugs and learn something, but really the way to go is to use a gas analyzer or better yet, a gas dyno (gas analysis under controlled loads).

    Thanks, Anton. One of my local mech’s suggested the same thing with the plugs and gas analyser. I haven’t looked closely at the plugs in the bike since I installed them new about 4k miles ago. I’ll have to pull them and take a look. I might post some pics.

    How does a lean or rich fuel mixture affect running temperature? Does lean generally run cool or hot? How ’bout rich?

    No particular reason I’m asking other than curious. My GS used to run a bit rich (it still might, but I haven’t really looked into it yet), and I’ve suspected that that was the cause of some overly-warm running.

    While I’m at it, I’ll ask the next logical question…What are good ways to evaluate the mixture for either condition?

    Thanks!
