Thanks,
I looked in the tech section/cam angle and the marking on the helix for the 51-43 is 8FA00 ??? has me puzzled...

Yeah, my handy dandy wall chart shows 8FA00 also. I have one of those helix's that I ordered by the part # off the chart. It is indeed a 51-43 with 8BVFA marked on it. I think Yamaha's numbering system isn't set up for that many digit's in that format (51-43 instead of 47,45, etc) so they just use two 0's. That's my theory anyway!!
