Haven't been to Jennings in 10+ years, going for a test day in a week or so on the FZ / R7 Gearing? Same as Barber or a tooth taller in the rear? I run 15/44 at Barber. Soft compound (0129) tires ok there or will it eat them alive? Thanks!
Jennings eats tires pretty good. Mediums would last you much longer. Either way you'll have to do a flip at some point to even the wear. Gearing I can;t help you with sorry...
This last winter, when we were riding at pace, we were using a single MA 0129 takeoff - per session. We could ride for 2 on one, but the lap time would be off a couple of seconds. Ken
