The science behind breaking in engines has been thoroughly researched and millions of pounds has gone into R&D for this sort of thing.

I would read up on what big manufacturers say on the best way to run engines in. I personally justify my break in with how I feel. And feelings don't really provide much solidarity for this kind of thing.

I like the idea of gentle run ins with heat cycles cause it gives the opportunity for the metal to distort and contract and distort. Taking out any high points in the expansions.

But that's just a feeling rather than facts.

Glazing the bore is going to happen if you literally build a fresh engine, then take the engine to the max non stop for the next thousand miles. You're talking about shortening the life of a two stroke whose top end should be rebuilt every 10k anyhow. So it really makes no odds. Stop worry about it so much.

Either way, get it runing and put some miles intonit before hammeringnit. That's my advice. Two strokes don't last forever so it's a moot point if it lasts +-1k miles. The main thing is getting that fueling spot on.
