904 race build

Loose band adjustment, too much clutch clearance, Orifice in the case? Maybe try smooth thin (forward clutch) Red Eagles in the direct
Band is adjusted correctly.Not sure about the clearances but going to find out when I remove trans.In the past my buddy just used a standard rebuild kit but looks like time for better parts.I have heard about changing the front drum spring to a multiple spring pack and modify pump for more pressure to third.
