I have an AC roller secondary, keyed 25 mm shaft, 57-50 degree helix with a red/white spring. Aftermarket PSE roller. Not sure what year or model this is from. I had it on my old ZX 800 with a turned down shaft. If you can use it send me a PM. 100 bucks plus shipping I can send pics but I'm too lazy to figure out how to post them jim
