I also blame lock ups on the street. With the flyweights. Disengaging the drive train doesn't always happen all the way. These six speeds can't take that. On the track, with either clutch driven or engine driven. Doesn't matter. We aren't using clutch for disengagement. We are killing power with ignition, fuel or both.

 

Just a little follow up from my slipping issue…replaced the clutch with an Energy One extra disc kit and spring also used B&M Trickshift and I couldn’t be happier! Slipping seems to be gone and no more “clunk” when dropping it in 1st gear. The friction zone is quite small but overall I’m happy!
