Cb750k6 clutch disc query

<< < (6/7) > >>

Paulreade:
I might first go down the route that they have sold the wrong one in the first place and ask for an exchange - worth a try

Paulreade:
By way of an update: d avid silver spares unfortunately cannot assist on the clutch issue. They appear to supply a clutch set which comprises of all slanted oil grooves with current part numbers appertaining to the k6 bike. They state Honda made the changes to all slanted friction discs away from the 6+1 set ( 6 straight grooves + 1 slanted grove disc ) and that they supply this for the 'k' series bikes and have had no negative feedback to date.
It's tempting to try the discs before I invest in a ck1145 kit but I have yet to make that decision.
What I have checked is that the friction discs are all well within their service limit ( in fact they are hardly worn at all from the standard values. - leading me to suspect the clutch may have already been replaced. It was biting at around 3/4 which led me to think the clutch was at the end of its life ?.
What I have noticed is that the old springs are way over length. The replacement ( new) springs I have are of the standard length but the old ones are approx 3-5 mm longer - again this leads me to suspect the clutch has been out at some point.
I am tempted to replace the springs with the correct ones and clean all the discs and reuse them for a while longer.
Is this sound logic if the discs are all in spec ?
Also what method would be advised to clean the metal plates before rebuilding the clutch ?, is it a case of brake cleaner and a very light touch with wet and dry ??????
Sorry to rake this up again but it has brought out quite a bit of debate.
The outer friction disc on my clutch was fitted with the outer edge of the grooves trailing the inner, I will flip this as per triggers advice and have the inner edge of the groove trailing the outer as per the attached to see what effect this has ?
Regards
Paul

Trigger:
If Honda made changes to all slanted plate then why are Sliver doing this kit as 1 oem and 6 aftermarket friction plates  ???.

Clutches can be a little strange and i would not believe the Honda service limits. I have had shed load of clutches slipping and on removal of the plates, they have been with in spec. New friction plates in and everything was working as it should. A plate can be with in spec but, if it is old and brittle it will slip.

There are two different lengths of springs fitted to the 750's. Make sure you have a K6 clutch basket, just because your bike is a K6 it, doesn't mean all the parts are K6 ;) 

Paulreade:
Duly noted trigger, ck1145 required.

Plot thickens as regards the basket query ???. Would it be too much trouble to throw a few pointers to see if I can clarify if it's a k6 basket ?.
It's the first basket I've ever touched - let alone identifying it's type ?.
Is there a specific thing I can check or would you need photos etc ?
Many thanks
Paul

Trigger:
I would just fit the CK 1145 and the spring that came out your old clutch basket. The shorter springs can be a bit of a bugger and i think they maybe a supersede part. Check the PN of the springs against the original PN for the K6.

Have not had time to look for a K6 basket and take photo's as yet.
