Re: 1.3 Rocker Arms for Cam break in
do racers still do the light ratio rockers / light springs these days ?. prefillng the carb with fuel / setting about 10 degrees advance timing and loading up the crankcase with a good brand of breakin oil with lots of phosphorus and zinc in the blend ( check the label if those ingredients on the bottle label ) a quick crank / firing up to a good high break in rpm should be all you need ... maybe I.m old school on this method
