Warning:
This is a very controversial topic !!
I quoted the first sentence.
This is not my first motor and I broke in all off motors the same way. I run it easy with bursts of acceleration in all gears, for the first 500 miles. The only engine failure i ever had was a bad oil pump. It also helps me sleep better at night when my engine builder,DCR and AMS all believe the same.
Thanks for the info and a different point of view.
PS. here is break in instructions on ams's web sight.
