went back the next day, with helper to help keep the master full, with handle bars turned to keep master cyl level. the fluid was low, but not low enough to uncover any of the ports. I believe the clutch is WORN so the slave cyl piston is further down in the cyl thus taking more fluid out of the master cyl, that is why the fluid was a LITTLE low in the master cyl. just like the brake master cyl will go down when the brake pads wear down as the pistons in the calipers are pushed out more to grab the discs. brake master cyl low? baring leaks in the system, the brake pads are worn down n ...need replaced before the pistons gets cocked in the cylinder of the calipers and ruins the calipers...if they are not ruined by being pitted/rusted already.
got the 1" bore syringe (E bay 5 for $5 from HK) with right size of fuel hose on it (~1/8" ID) and 2 hose clamps to get it tight on the syringe and snug on the bleeder and started to PULL on the piston in the syringe. with a ~3.4" stroke it can pull quite a bit of vacuum/fluid, helper kept master full. clutch seems to be abt where it was to begin with ... finally. Cant see the bubbles coming through the black fuel hose, but it is easier (for me) to find (I had it already) and really do not need to see the bubbles... the clutch/brakes are going to work or they are NOT. suck enough fluid through the system... I WOULD think IT HAS TO WORK, yes.
I was thinking about reverse bleeding it, fill the syringe with brake fluid, bleed the line from syringe to the bleeder, put hose on the bleeder, have someone ready with another syringe/rag at the master to suck out the excess fluid and PUSH the fluid from the slave cyl through to the master. BUT WHAT A MESS THAT WOULD BE... especially on a NICE BIKE. Brake fluid is very HARD ON PAINT. I would have saved that as a last resort.
the gravity thing might have worked...with time. I opened the bleeder, before testing the clutch from leaving it sit overnight, (D'oh), and the slave was full again. I read somewhere that ppl can tap the slave cyl while bleeding to free up bubbles in the calipers on vehicles as bubbles can get trapped in the calipers and tapping the calipers helps free the bubbles?
I was careful with the Teflon tape to not get it over the port on the bleeder thing. the thing abt the Teflon tape is that a person has to put a wrench on the bleeder to loosen/tighten it, where without the Teflon tape a person can do it with their hands and it is probably tight enough for the bleed process? speedbleeders would be a fine thing. but without the Teflon tape it sucks air past the threads, which with a clear (aquarium?) hose, a person is constantly seeing little bubbles and wonders if it is bleeding right or not. sometimes it might take more than one process to get all the bubbles out of the system? time will tell; for now, it seems ok.
