Will rebuild master cylinder. Only kits exist can not get new master cylinder. Bike too old. So I will not be replacing the orifice but plan to blow it out.

This would cause poor disengagement due to the air bubble. My issue is the opposite. Great disengagement no engaging.

No pressure being retained. Opened bleed port on slave and little came out. Nothing found in master cylinder bleed port but I did not have a fine wire to probe. I just poked with a small paper clip. Placed bike on center stand. In gear rear wheel locks with clutch lever released and turns with resistance with lever squeezed. Started next day. Outside temperature 54°. Clutch engaged initially. Checked again with engine warm about 170°. Clutch lightly engage then wouldn't. Clutch friction point way to far out on lever. Almost at point where lever sits. I know the clutch pack is correctly installed.

Like a check valve.. That makes sense. I was thinking the pressure plate is acting like it's being held away from the disks.

Installed new clutch on 2007 800a. Flushed clutch fluid. Changed oil using Honda recommended type. Motorcycle did well for ride around neighborhood which is about 2 miles. Took bike out today. Was not engaging after about half a mile. Worsening until there was no engaging at about two miles. Friction point was moving farther and farther on the lever. The correct clutch pack was installed using a manual. New pressure plate springs. All bolts torqued to spec. Clutch area inspected and nothing unusual found. Clutch lever is snappy. Pressure plate springs are pushing back. Thoughts?
