CB175 Clutch Hangs

I have a problem that has everyone scratching their heads. I have a 197
CB175 K6 with 11k miles on it. It drives fine with no clutch slippage
It shifts fine...when moving. But, when I stop for a ligh
(particularly when it warm) and sit there for a few seconds, the clutc
locks in the dis-engaged position. The handle moves freely the ne
clutch cable moves, but the clutch won't engage and the bike won'
move. I can rev the engine, but I have to sit there listening to th
frustrated drivers honking behind me. I've also noticed that eve
though the clutch egages at all times when moving, it's not ver
smooth.

Speculation has included bad clutch plates, bad springs and a ba
bearng on the actuator. Has anyone had this problem? Any idea on ho
to fix it

 

I see you refer to the "new cable". Was the clutch working fine before
this was fitted?

I'd start by checking the cable run and/or adjustment. I'd also check
that the sprocket cover is bolted on properly. The clutch actuator is
mounted on the inside of it, and if the cover is loose, the clutch
won't work properly, as the actuator, instead of pushing the clutch
pushrod *in*, will push the cover *out*.

If those two simple things are OK, I'd pull the clutch. I'd be
surprised if there's much wear in it at a mere 11,000 miles, but there
could be.

clutch springs and is incredibly simple and as B12 suggests, there
could be notches in it. That would mean somebody's abused it, because
normally those clutches are good for 40k+ miles.

 

Check the Clutch Basket for ripples where the clutch plates sit .
The plates can catch on the edge of the ripples .
You can file the ripples off but you have to be careful that you file even
amounts off on all the fingers otherwise you will through the clutch basket
out of balance.
I hope this helps .
