1199 clutch lever getting closer to hand grip

I've noticed that my clutch engagement point has been moving closer to the hand grip gradually over the last 6 months and I've actually had to adjust the little lever position adjustment lever to keep the clutch lever at a comfortable position and now it is all the way out so I need to fix this before I can't disengage the clutch.

Have any of you experienced this? Is it the clutch master or slave likely? A leaky seal maybe? I don't have any brake fluid leaking on the ground that I can see but the fluid in the clutch master reservoir does look a little brown. Maybe there's some rust in the master and it is bypassing the seal?

Thanks,
 
My 1998 Dodge Cummins had hydraulic clutch. Drove that thing 15 years. 200k miles. Never had to bleed the clutch

Try putting some Teflon tape on both bleeders but first remove and disassemble the slave

Mine had a bunch of muck behind the piston
 
I get air every so often. Can bleed it and get the lever back to normal. Can also sometimes tilt bike and operate the lever. Sometimes that's all that's needed to get the air to burp out.
 
Thanks for the replies. I wonder if its a bleeding problem because it seems if I ride it all day it gets a little better. I'll try that. Probably wont have much opportunity to ride for a week or two now though. The weather man says we're getting pretty cool weather for the next week or so.
 
just crack it and creep in the lever in to get all air out but no need to expel fluid. Tighten the bleeder and ride

yeah I don’t think it’s a hydraulic clutch action problem but more of a Duc hydraulic clutch action problem

Eventually upgrade clutch master, slave and line

I've upgraded the slave to Oberon and still have the same issue. Some day i'll maybe replace the master but idk its cheaper to bleed once in a while.
 
Carry and 11 mm wrench with some small plastic tubing and some tissue paper, under the rear cowling. Cause you gonna need to bleed it to get the air bubble out sometimes when your not home. It all fits in there. I’d not just pop it without some tubing to catch it, as brake fluid will eat up and scar plastic and paint.
 
Dont worry about it, its really such a basic operation that you can do it in 2 minutes. When out and about all you need is 11mm ring spanner and an absorbent cloth. Put the spanner on the nipple and loosen it first, then lightly nip it up (this give more control when bleeding) Next, with the cloth over the nipple and the spanner in place, pump the clutch a few times and pull it into the bars. Holding it in loosen the nipple slowly until you feel the pressure on the lever relax then close the nipple and release the lever. Once is usually enough but if it still feels loose then once more keeping an eye on the reservoir.
Job done, go riding
 
I just put some Stahlbus bleeders on V4R masters and can tell from their action that it will save bleeding/flushing time.

Have replaced slave on 1199 and v4r with ducabike and CNC respectively but kept master clutch OEM. The 1199 clutch is now great.

V4R clutch still seems to need bleeding a lot, maybe the dry clutch plates are on the way out...I thought about wrapping Teflon around the bleed screw thread but it worried me that Teflon degraded into the system and caused mischief - admittedly I am not a chemist but I want the brake internals to be the one area of the bike free from any contamination!
