Well, Just changed out the old stock clutch line to braided SS, after having my clutch lever loose its pressure if held in for 40 seconds or more, in 1st gear at a light. Then the back tire starts to move and I had to shut the bike off to get back into neutral.
After the SS line is in place, now it only keeps lever pressure for about 10 seconds..
The old fluid was very dark, like mud, before working on it today. It looked OK in the sight glass but after it lost pressure multiple times 2 weeks ago, I parked it.
I used the mighty vac to try and suck any air from the bleed screw, near the clutch cover. This looks to be harder to do than the brakes, because the clutch has a spring in the system. So feeling for that No-More-Air, hard lock-up point, while pumping up pressure, is hard to feel for.
My question is, What would cause these symptoms?
1) Hold the clutch in,, you start to feel the amount of force needed to keep it depressed, diminishes after 10 seconds. If in 1st, the tire starts to grab.
2) No visible leaks anywhere.
If the piston, inside the clutch master cylinder, is in a closed system,,, could there be a micro hole or problem with the 0-rings, allowing fluid to seep back into the reservoir?
I'm trying to figure out why it feels like a pressure leak, but there's no fluid leaking anywhere.
What do you think?
