I have done this on my prox you will have to get a longer bolt and a key for the keyway from cat and a washer from cat cause you need a larger diamitor(spelling) than you use washers the same size as the spacer bushing that goes in the hub of the clutch. Make sure you set the offset buy adding or sub tracting washers on the shaft behind the clutch I am running a 55/53 with a dark green spring and am running heelclickers in the primary but you could trygoing 2 to 4 grams heavier on your clutch wieghts.if the rpms are to high on top go even heaveir on the wieghts If they are to low go lighter on the wieghts do not use the secondary to tune the running rpm as you will lose clutching efficincy.try this I hope this helps.
