Dragging clutch
Nurse Julie:
Did your replacement clutch kit have the same amount of plates of the same thickness and did you replace them in the same order and are all the metal plates facing in the same direction, ie bevelled edge all facing outwards or all facing inwards?
Scottvincent:
Thanks for the response. Yes, I fitted the clutch in same order, bevels the same way. The symptoms were the same with the clutch when I bought the bike, as when I replaced the clutch with the new one. I also replaced the springs.
K2-K6:
Are you adjusting the clutch arm without the cable connected?
It's easier to do as above to set the clearance. It should end up with the cable and arm about 90 degree to each other when the clutch lever is fully pulled in to the bar after setting it correctly.
With the cable disconnected the clutch end lever should have about a mm or two free play at the end of that lever if you move it against it's spring. This would just about give clearance between the internal mech and starting to lift the plates, which then should be enough to lift the plates clear from the travel built into to lift cams.

Hi
Thanks for replying. Yes, I do not think that adjustment is the problem. When adjusted by the book(clymer) screwed in until it touches and backed off quarter to half turn, the angle of the arm is approx 7 o’clock. The clutch action (from the clutch lever) is smooth. The clutch lifter slides in and out smoothly when the lever (handlebar) is operated.
I have just taken off the outer cover and the clutch lifter plate. The clutch plates all look correctly located within the basket. I will remove the clutch plates when I return from walking the dog. I have done this procedure at least half a dozen times over the past two years and it is doing my head in!
Any suggestions very welcome.

Dont know why but i think i read somewhere of somebody putting a washer in the wrong place. Take the whole clutch off and check with a parts book
