I'm not sure if I'm in the right form for this but my 03 FLHTC primary is under pressure. The first time I noticed it was when my stator **** the bed, rode the bike 6 miles to the shop went to drain the primary and the oil shot out of the drain hole, I assumed that the stator over heated the oil. Well today 2 months later I went to do an service and the same thing, drained primary after a 6 mile run and the oil shot out of the drain. Anyone got any ideas?

 

Check your venting, your primary vents through the flat on your clutch adjuster screw and then through your transmission and out the transmission top cover hose. Make sure there is no blockage.

 

I have seen mud wasps get in the trans vent hose and cause all kinds of issues.

 

I've seen oil get pushed out the clutch cable from a clogged vent.
