Out of interest, can anyone tell me what the rocker ratio is on the Sprint rockers?

Come on Mart, use your head! Measure the distance from shaft centre to each pad centre then divide one into the other! The answer is left as an exercise for the student! (and cos I don't have a Sprint rocker to measure)

....... but to put some actual numbers on this I reckon the valve side is 45mm and the camshaft side is 55mm which gives 0.82 ?
