I did a recent trackday and experienced an interesting issue.

At times the EGT was reading up to 1350 deg, but it didn't actually feel lean. The temp rise linear - in that is would keep rising as the throttle setting and RPM increased. I decided to ride another session and just didn't rev it out so far.

I am pulling the head off tonight to have a look, but I do not expect to see any damage.

The question is - is inserting the Koso EGT probe so that the tip is in the middle of the pipe actually too far? The reason that I ask is that a friend tried this setup on his GP bike several years ago and the probe over read temp and also dropped 6hp. Removed the probes and the 6hp reappeared..

thanks
