Doug…. What’s your feelings on oil relief holes in the drums (help evacuate fluid/centrifugal weight)? Both of my older Lofgren builds had them including the 904 I’m currently beating on.
I've never used them. How much oil is in the drum when the piston isn't applied? Good question. However the only time pressurized oil is in the drum is when the clutch is applied. That clutch pack always applys plenty quick. We all know the dreaded overlap. So why do we need them? Maybe someone smarter than me can shed some light.
