Interesting to note the difference between the stocker on the left and the Andrews cam on the right. The Andrews is a higher lift, shorter duration cam designed to improve mid-range which is where this motor will spend the majority of it's time. Stock cam at 240k kms was in perfect condition, btw. Show me another air-cooled motorcycle engine design that originated in '69 that can produce a cam looking like that at 240k kms? Honda 750K, you say? Fahggeddaboud'dit.
