Yosh crank

[Grumph]

Came across this in a pile of REVS I was given. Dated Feb 1981.
This is what those of us struggling with GS/GSX race engines need...

Spyda's probably got one depending on how many times his Yosh GS's have blown up and been rebuilt.

you'd nearly be able to take that to the right people and get one 3d printed....
