Is a shifter cover gasket necessary for the spacing ? Went to ride this thing after I removed the cover to fix an oil leak. Gasket tore so I cleaned it up andused some permatex brown to seal it. No more leak. The damm thing won't shift.up.Real stiff. I think maybe the spline shaft is binding on the cover. Pulled the cover back off and rolling it back and forth it seems to shift the drum ok. I guess you must have that gasket ?
