have a clutch kit that came with a 2007 gt i purchased a few yeara ago I believe it came from pioneer performance. Trying to find out what the helix is. Only markings PRXAS. Does anyone have any ideas what it may be?

Pretty sure Bruce told me that all the parts in his clutch kit are yamaha. But I'm not positive on that.

Just posted this in another thread. It's easy to read a helix with a protractor with a magnetic base ($10 at Fleet Farm) a 5/16 or 3/8 nut and a level bench. Put the helix on a level bench and put the nut on the magnetic base next to the edge and slide it up and down the ramp on the outer edge. I can usually get with in a degree or two.
