Well I got Jordans XLCH cylinders sized for these .040" over pistons. The cylinders turned out perfect, round & straight with the proper fitment. Gotta check those Vtwin pistons though, one was .001" smaller than the other. Then I figured since it has been so unseasonably warm lately I might as well go for a cruise. Jordan ran into a guy that I went to college with and bought this roller off him. Figured we can drink Blatz and ride it down the hill in his back yard! Neat huh??
