Not sure I understand the SeaFoam thing ??? Are you adding it to the gas ???Update. Not a great one.
I FINALLY finished putting this together, with the new clutch hose. It still slips. WTF?
So now I've done about everything that's doable on the hydraulics. Starting to think that maybe I didn't man up enough in the "test it with the slave cylinder removed and see if you can make it slip" test. It doesn't slip really bad, but it slips. And that I may never have had a hydraulic problem at all.
My immediate plan is to try some SeaFoam in the oil for 150 miles or so, then some fresh Honda oil and see if a miracle happens. Perhaps there will get rid of an additive from its prior life (I doubt it) or magically free up the oil regulator (doubt that, too), but it's a cheap lottery ticket.
After that, I'll look for a bigger hammer.
I too think you should have double checked for clutch slippage with the slave removed.
I recently did clutch diagnosis on a Wing that had it's clutch repaired at a Honda dealer. I posted that info here.
2008 2-whl 115,000 on ODM A customer calls up saying that a Honda dealer just replaced his clutch, and it still slips. I ask him to bring in the receipts, and his old parts if he has them. He dropped his Wing off and had the old friction, and steel plates. Neither showed signs of slippage...
