how are you folks breakin in your motors after top end rebuilds?
I know about keeping the r's above 3k for the hotcam for 20mins but what about the piston?
I was gonna run 10w-40 gn4 and after installing the cam and breaking that in I wanted to run the piston through some heat cycles. I was gonn ride it medium for 10 mins, let it cool completely. ride it agin another 10, let it cool completely. ride it another 10 about 3/4 throtle let it cool completely.
drop the oil and filter. ride it fairly agressively let it cool again and then that should do it right?
i have a je 416 with stage 2 hot cam. my motor was clean before the teardown and I lapped the valves to make sure there was a good seal. :square
my bottom end has about 50-60 hours on it
