Break-in needed?

[SawBrian]

Hi

All manuals for motorcycles, outboards, cars, trucks, tractors, mowers I have seen...have instructions about break in periods in its manual. If the specified break in instructions are followed the results will be better performance and longer engine life.

But many of you say chainsaws don`t need break in at all. Its just to drive it like any saw when its new. So whats so differnet with a chainsaw from a mower f.ex?

someone pls explain in depth.

It's controversial. Many new people say new motors have milling and tolerances that are so much more precise the old "easy break in" ways are no longer necessary (the easy break in was for old motors where tolerances were much more sloppy). The current wisdom is to run it hard, so the rings seat. This explains better, and really makes sense:

All motors are very similar, I don't know why the saw manufacturers have gone to a more modern "break in" procedure than everyone else has.

I bought a 2003 BMW R1150RT motorcycle in Nov. of 2002 that set me back $16K and change.

BMW owners / riders are anal about break-in procedures......valid or not. Me being me.....I rode it as if it was used. No special care or attention, but I didn't beat it up either.

Long story short......it's now approaching 20K miles, runs like a top, and doesn't use oil like so many BMW cycles do.

Moral to the story: Use common sense, use proper care / do preventative maintenance, and you'll be just fine.

SawBrian, I tried to answer your PM, but recieved a message that you either had made yourself unavailiable, or had been made unavailiable. It was a system-generated message.

What the h*** is going on?
