RE: How important is the break in procedure?

Ed,

Let's split what you wrote into two...

As was explained to me, by a respectable engine manufacturer, the ABC fit is at its best when it leaves the factory. The only ''break-in'' required is for parts other than the piston/liner combo. But I know that no one will agree with what I'm repeating.

I would say this manufacturer is clearly wrong...
If this was so, the engine's performance would be top-notch 'out of the box' and it would steadily deteriorate, as time is accumulated by the engine.

But this is not so. ABC engines perform better as time is accumulated on them.
I can tell you from my own experience with MVVS, that their engines gain 400-600 RPM on top with the same prop, by the time they run 6-10 hours.
From there on and until 3-400 hours, they perform the same.

If 'best fit' can be described by optimum sealing and highest output, then they were not at their 'best fit' when new.

Some of them stay in business because of us users, who are willing to shal out these outrageous sums to buy engines; and then proceed to 'follow the manual'.
If it doesn't last, many just buy a new one, of the same type and brand...

Some don't continue to stay in business... Webra rings a bell?
