Very interesting, I'm going to ride on PiperChucks coat tails on this one. The manufacturer has already proved what downunder is trying to prove and beleive me it probably cost them allot less money to prove how to break in ABC engines. I just got a MagnumXL .28ARNV (ABC& Ringed. The first thing I noticed was it comes with a 2 year warranty.

Now lets say I use downunders advice to break this engine in and damage occurs with in the 2 years , should my warranty cover the damage ?

The point is, if you are one of the people ignoring the manufacturers advice on maintaining your engine then please don't send back any damage parts to the manufacturers do your own methods of breaking in the engine, subsequently driving up the cost of engines,do to excessive returns, for the honest people who follow the directions.

Just my 2 cents.
