Still fat, but will continue to play with it even after the long bike is fixed. Kind of fun, hit a series of feathering the clutch today with long azz wheelies lol

Out in the first round. Made some changes to the clutch, primary and air shifter over the winter and bikes not shifting into fifth. Something is off. Miss having my rider but hit a p/b 1.28 60 and 3.7 330. Nice to get to the track after all that’s going on.

This happened to me two years ago and ended up being busted dogs on fifth gear. Shifted fine otherwise but would not shift into 5th with air shifter.

Went into fifth on the last pass last week, goes into fifth on the stand. Only have 30 something passed on the trans not ready to condemn it yet. But... Going Make some changes if that’s not it I’ll swap the trans. Got nowhere to test it. Second or third might be able do on the street. 5th, no way, lol! Maybe on the dyno?

I could foot shift into 5th at a reasonable speed and could put into fifth with motor off but on the track with air you could hit the button multiple times and no shift. Let me try and find the pics of what broke on mine.
