Bob, I suspect that the Chinese are making the engines a little better, or
they have switched to softer metals, because I have heard that the newer
Chinese engines take a little less time to come in on the average. I have
no
scientific proof of this at all. But lots of folks are re****ting, via the
web, that the engines, while not as readily broken-in as OS, are better in
this respect than they were back in "the old days".
I'm not knocking Italy's Super Tigre's efforts either. CNC machinery
hasn't
been around all that long, so the Italians may not have been set up as
well
in this regard as the current Chinese manufacturers.
These are simply my impressions and nothing more.
