1.23.
the shifter got stuck from 2nd-3rd. i have air shift and the air kept the shifter stuck between 2nd and 3rd. i tried to pull the handle but failed which resulted a few bumps on the rev limiter. i actually had to look down at the shifter to see what the problem was.
I would imagine temperature and track conditions have a lot to do with bite. Could you bump the pressure up a half pound per pass and see if the 60' starts falling off?
