Look'n for a left side cover for the Fireball or Ward's Sport bike 50 engine. They have the shift mechanism in them but if you have just the cover that would work for me too. Also, I could live with the moped version side cover. I want to set up a hand shift on my Benelli moped.
I have the 4 speed engine but it is without the side case and I want to keep my original motor intact.
