Re: The definitive break-in procedure thread.
There is nothing wrong with getting on it hard fairly early in life. Some of that is whacked.....sure bogging it or constant RPM is not good early in life. OTOH, babying an engine too much just extends the time to properly seat the rings. I read this stuff about people taking 400+ miles for the engine to break in, and that tells me something isn't right.
MAYBE 20:1 for the first tank, but even....
In my case I never did that. My first tank was 30:1 or so, I was battling the usual HT tuning and set up issues, once I got that stuff out of the way, second tank 32:1 the engine started getting more power, maybe third tank power got up to the point where it is now. Nice and well broken in.
