Not tried on a 4 spring A65 clutch.

Did try on a 4 spring A10 clutch.

Not enough room for the extra plates on the clutch centre drum. Could only get one extra plain and on extra of the thin bonded plates.

I would question whether there is enough space in the A65 4 spring for 2 extra bonded plates and 1 extra plain plate.

You could consider fitting the 3 spring clutch which is of simpler construction and has more plates anyway.

I put 1 extra of each in my A50 ie 6 and 6 slip cured but difficult to put in.

Seems odd they would sell a kit that will not fir in the basket, but ive come across a similar situation with Lambretta clutch plates, the thickness of the friction plates is too much to get the circlip in to hold it all together, I had better strip it down and take a look at what is in there and its condition before i order any thing, just nice to get the opinions of people who have actually tried them .
