I've got a secondary clutch with a 8BV 30 helix on it and it doesn't show up in the Yamaha helix chart. I know the 8bv31 is a 43 angle but I would like to finf out what this 30 is. Any ideas?

its also a straight 43, found it in the 1998 book.

when they add the 1 at the end of a number that indicated that it is the newer generation helix cut for overdrive.
