Yes, I think that’s the model. I remember thinking it pulled really hard compared with my 500 AJS. There again, the AJ was probably quite worn out – in those days funds dictated all repairs were with used parts.
I had several buckets and boxes full of old cams, heads, all sorts of things. Rebuilds were a primitive form of blueprinting – cams with the biggest lumps, best piston/bore fit and so on.
Wish I still had it all.
