Thanks for the good words folks.

Matador, FWIW, through a couple decades of New Motorcycles and New cars, I've found an aggressive, High Load Break in to produce the best results. This doesn't mean Spinning it to rev limiter, what more important is variable high loads, and engine braking. Using lots of both has always provided me with motors that use no oil, produce good dyno numbers and last a long time.

However, there is so much discussion/argument about break-in on the web and I am sure this forum that all you need is a search to find dozens of opinions.

Per factory though, I believe it said something like what you've posted.

Thanks Revlis,

by the way, what do you mean by variable load/high load break in, you meant I can occassionally rev it beyond 6,000 RPM, as long as I don't stay at high rev long ?

No not really. While I personally do not live in fear of high RPMs during break in, what I am talking about really doesn't have much to do or need high RPM.

By high load I mean full throttle in third gear from about 2500-4500/5000RPM. Never Bog a new motor, but essentially lots of full throttle pulls through the meat of the powerband then letting it coast back down from 4-5K RPM to 2K RPM.

There's no need for high RPMs, you just want to subject the rings to good heavy loads early. The coasting back down is beneficial as well.
