good info

I agree, the guy has that right idea, good info. I think there could be a difference though, with a brand new factory motor and a motor you have some local person build. I think that mechanics have their own ideas and build there motors accordingly. If you go to a builder that does all race or performance motors verses one that thinks he's doing you a favor by setting up clearances tighter for longer average driving engine life there could be a problem. The perfomance guy knows that full throttle operation is part of the break in.
It will be interesting to see the future article on bearing clearances.

A long time ago I bought a brand new V65 Sabre. I believed in this theory of breaking in like you drive it also. Well to make a long story short, I trashed the engine in 500 miles and they had to put a new one in. I broke the second one in the way they recommended and never had a problem with it. That was a very fast bike.

That was my experience, I am no expert.

I have to include that the V65 was a 1985 model and I am sure that it wasn't made to the tolerances that are available today. Therefore, my experience here may be disqualified.
