Hydraulic clutch issues

I fired up my bike the other day and ran it in first gear on the center stand, pulled in the clutch, and the back tire kept going like I never let off the clutch.
I bled the living daylights out of the clutch master and I'll try it again.
The clutch has never slipped, so I'm thinking this is a hydraulic issue and not a clutch plate issue.
Anyone else have the same experience?

 

couple things... how many miles are on your bike? what caused you to test your clutch on the center stand? if it is a hydraulic issue then you may also have a bad master cylinder, your clutch lines might be expanding when you pull in the clutch, you might have bad/old hydraulic fluid, the piston that actuates the clutch could be binding and not moving under the hydraulic pressure...

 

the mechanics of it all

With the clutch in you still have all the plates winging by one another, they will drag it is the nature of the beast.Don't sweat it.If you have shifting problems (bangs hard or hard to get into gear) then worry.:thumbsup:

 

do you let it warm up?

 

more checking to do

The bike was good and warm when I tried the clutch out.
I tested it because it was a bit hard going into second.
It does bang a bit when I shift it in and out of gear.
After reading about the vulnerability of the trans on first gen. bikes I got worried.
Could be the piston in the slave cylinder is binding up and not moving.
That is what happened to my rear brake caliper. I replaced it last year.
Also, is the shift rod supposed to be loose?
I pulled on it and it just comes out from the slave cylinder side.
Thanks for all the replies.:thumbsup:

 

I don't know if this bike has adjustments in clutch spring tension. I had an old bike that had a problem with a dragging clutch, due to the springs being unevenly adjusted. At least I think so.

As to your test, I think even perfectly functioning bikes, with no load at all on the back wheel, are going to have the wheel rotating when the bike is in gear with the clutch in. Your other tests are better, i.e. sitting on the bike and the bike jumps when you shift into gear, or hard shifting.

 

JUST change out the old fluid and bleed the system; less air=better clutch control.

When you bleed, it's best to remove slave cylinder from cover and fully retract piston using a C-clamp.

 

good tip

Thanks for the tip. I was bleeding the system with the slave cylinder mounted to the bike.
I'll give it a try with the clamp.:thumbsup:
