Engine break in

[FX1 696]

I know how to break in an engine, I’m just trying to remember a specific method I read about years ago. There was an article, an unusual method of break in. I remember reading it because somebody mentioned it on this site. Anybody know what I’m talking about?

Some guys like to do overly complicated breakins involving cool down periods. Keep it simple, The first tank 32:1 mix and no more than 1/4-1/2 throttle and alternate your speed not sustaining the same speed for extended period. The second tank no more than 3/4 throttle except for a very brief wot blasts. Third tank, send it.

ride it like you stole it right after it has warmed up.
go wfo for short runs and vary throttle a lot but ride it hard.
the idea is to build up high cylinder pressure to seat the rings properly.this won't take but a few minutes.

Yes I know the basic concepts, just trying to find this specific article, I believe written by an engine builder.

20 min idle, cool down
20min varying to 1/4 throttle, cool down totally
20min varying to 1/2 throttle, cool down totally
20min varying to 3/4 throttle, cool down totally
20min varying to full throttle, cool down totally
Ride it like you stole it

read it well,you'll see that rings seat in very quickly.just enough time to get things warm and hammer it.
