Good question. Hell if I know? I'm schooled with something new all the time I go out to the track. I think it has something to do with the air temp outside. It was pretty chilly both days, and that condenses the air and drops the air pressure. So figure 34 off the warmers, then out cooling off racing thru that cold air. I should bring my temp gun next time.
I think they called for 29 at the rear hot off the warmers. That showed no problem. I'll pick the rep's brain for a few answers next time out. That or next time being called into the shop, I'll ask my buddy.
Strange, but when I went to the winner's circle, looked at 1st place's front tire, it was like new. But that was a full on race slick, no grooves like we used.
Hell, go a pound up or down at a time with cold tires. See if it helps to scrub away the sheering. Two out of the fleet is one day a pound down, the other bike a pound up. Who cleaned up better?
Question, does your duc have any kind of axis telemetry? Guy was telling me you're leaned over, back end wants to kick out, but it intervenes so you don't. Don't remember the year of the bike he rode?
