Title: 695 time for new clutch plates?
Post by: Two dogs on September 25, 2012, 07:35:16 PM
My wife's 695 ( 21,000 Ks ) clutch friction zone is only small and at the end of the throw.
It is hard to judge as my bike is a dry clutch and feels so different .
I took it for a ride just then and it is quite hard pulling away at the lights on a hill and especially doing a U turn  as
the friction zone is so short and sudden  [puke].No wonder she is having trouble .
No creeping or slipping though.

Time for a new stack ?

If so should I go OEM or aftermarket pro/con

I plan on doing installing myself .
Thanks in advance  [thumbsup]

That's "normal" behavior for the wet clutch used in 695's.  Mine is just like you describe and has been since day one.

APTC is the devil!  You can source any of the non-aptc wet clutches, then sell your snazzy "slipper" for about the same money.  The lever pull is a little stiffer, but the friction zone is no longer a moving lightswitch that you can't feel.

As a bonus it makes replacement clutch packs way cheaper.  Assuming my ebay seller was honest about the miles on it, I now have the same miles on the regular style as the APTC.  Slow speed stuff is way easier.

The only caveat is it may take a while for the oils to thoroughly soak the plates depending on whatever the one you get is used to.

Lots of people swear by the APTC, but I find no difference at the rear wheel with my hard downshifting, lots-o-engine-braking riding style

You need the whole deal.  The baskets, hubs, and plates are different.

I'm not seeing any on fleabay at the moment that I am sure will work.  I do see one for an 848... but I don't know the specs on the gear off the top of my head.

Edit:

Although I now see you are across the world from me...

This is an APTC

this is approximately what normal looks like

The attaching bits are different for the little bikes, but I can't find a good pic.  The biggest difference is the strange thing on the left underneath the plate stack.

The APTC friction zone is definitely narrow and abrupt and out there, but I never found it totally sucky.  I wonder if you might have some air in the line and a good bleed might help a bit?  Very early on I upgraded to adjustable CRG levers (and properly set the plunger free play) so I could alter the takeup point - I remember really liking the change.  Good bit cheaper than new plates or a different type clutch.

Adjustable levers might have helped me, but it could also be that I suck at clutch modulation.  I've daily driven an RX-7 with an aluminum flywheel and a 6-puck sprung hub clutch.  It had about as much low speed (sub 20 mph) driveability as the duc with the APTC.

Same here, except the CRG part.
