I'm not sure, but the "not over 2000 rpm's" thing might be refering to the practice of not exceeding 2000 rpm's until the engine is at normal operating temp., which is a very common practice around here. Most of the guys that I talk with here, and elsewhere, pretty much work the heck out of their engines, and they run better for it.

I was going to mention about the chemical reaction thing on the rubber batteries but thought I was wrong. Would be the first time. :

Typo DD4x4 or are you really that good?? ;D

 

I don't know if the battery thing is true or not but I've always put the batteries on a 2X6 when sitting on concrete & probably always will.

As for the break in I take it easy the first couple of thousand miles just to let everything get seated & drive it like I'm gonna use it.

No typo, I'm really that good. : :

 

New batteries now have a polypropolene case that does not let charge migration occur like the older cases of a different material.

About 15 years ago my Mom had a battery to crack the top of the case in a minor accident. Sat the cracked battery out behind the shop, on dirt, under the eave and forgot about it for about six months. Next time I needed a battery for something I grabbed it, thinking I would have to jump it - surprised - it cranked a motor that had been sitting a while long enough to get gas to the carb. Ran that battery for another year or so. It was a Douglas battery - can't hardly find them anymore but that was all I used to use.
