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 ?
