This article is interesting for anyone running in a new engine;

Some good points about the rings being forced outward onto the cylinder wall by gas pressures to form a seal – as apposed to spring pressure.
So by increasing gas pressure (opening the throttle hard) you actually increase the evenness of the bedding in process.
Don’t use synthetic oil, apparently it’s so slippery that it actually "arrests" the break in process before the rings can seal completely (not sure I agree with that).

He suggests the best thing you can do for your engine is to change your oil and filter  after the first 20 miles. As most of the wearing in process happens immediately, creating a lot of metal in the oil. Plus, it flushes out the left over machining chips and other crud left behind in the manufacturing process.

are you thinking of buying new now? :D

No - have you ever known me to buy any vehicle new, I hate the idea of the massive devaluation the first time you use it.

But I have rebuilt a couple of motors, this process applies to the weed eater, lawn mower, chainsaw and any motor. Who knows I might get carried away and do rings and hone the bore in the bandit while I'm fixing it up

I've read something like that before, was an interesting read compared to all manufacturers specs, they dont suggest doing it, would be interesting to find out what is best.
