That means that the outside of the cylinder is around 160 degrees. Not very hot. You're never going to be able to gauge the temperature that way.

If the coolant isn't blowing off pressure at the overflow, you can be reasonably sure you're alright. If you need more info than that, get some temp tape from Pro Circuit.

By the way, your exhaust will glow red if you let it idle more than a minute or so.

In RacerX, I saw an ad for a rad cap that had a temp guage on it...

has anybody else seen this, or does anybody have one?

i think that would be a great idea.
