maxx perf:

6MS7= 48/42
MSR8= 52/40 (should say 7MSR8, cause it was out of a '98 srx 700 and that was the part# for a maxx SRX 700 clutch kit...the 6MSR8 is for the 600 SRX...don't know that angle.)

press the bushing out. maxx engraved the helix angles, on the bushing bore wall. put some green loctite on the outside of the bushing when you press it back in.
 
anybody know what a rpc3 helix is? its a cat helix for a cat secondary, but rpc was big into putting cat secondaries on earlier yamaha sleds. trying to find out the angle. its looking like a 58 to 62 deg start, but does anyone know the angle for sure? thanks.
