break in a must?
Okay, I know this has been aks several times, but I couldīnt find a 100% answer for it.
So many peoples say, that cars today donīt have to brake in, cause of the built quality. My tuner also says that it takes 50000 miles to break it in cause, donīt know what he meant exactly but I think he meant the materials are so exact and strong built.
What is after I install my new rods and pistons? Do I have to break it in? How should I do this, cause my standalone is not tuned and prigrammed now, I must go to the dyno and make WOT runs to adjust the a/f mixture. DAMN!
MY tuner say they never brake in new built motors on their rally cars and they never have problems with oil consuming, etc...

I'd say take it easy at first...

What is this crap?
Re: break in a must? (austrian ITR)
I thought valve seals and rings should be treated with kindness at first. Its a good practice to give the parts time to get to know eachother.
Even if there is no reason to do it, it doesnt hurt. The fact that synthetics are not used for breakin seems to imply that there is some sort of 'run in' time that allows metal to metal parts to wear against eachother to get the most exacting tolerances.

Drive conservatively with no boost for about 1000 miles. Unless of course you want to re-ring the motor afterwards.

A new motor needs break in, no matter who tells you what. No matter what the build quality. Go look at the oil of any brand new motor, there are gonna be metal particles in there.
I have years of experiance with 2 stroke motors, mostly ATVs and dirtbikes. These motors are perfect examples. For people just weekend riding, if you break it in for an hour, you will prolly get a good season out of it. If you break it in for a few tanks of gas, you might get a few seasons. Just FYI, my father has a 1980 CR250 elsinore with the ORIGINAL PISTON. thats right, ORIGINAL. The bike has gone through a few clutches in the years he has owned it but it only has slight piston slap. Granted he doesnt beat on it much, but not bad for a 22 year old bike!
NOTES: dont be lazy. show some restraint for a few weeks.

Re: break in a must? (RioNinja)
Are eninges run at all at the factory before they are loaded onto a truck and to a dealership? What about test drives and stuff? I know they don't keep new cars under 3000 RPMs for 1000 miles.

..i know a few NIRA ppl.. and one in particular breaks em in with 3 practice runs.. one at 20lbs of boost.. next at 25.. and the last at 30 with some spray.. its gotta break in.. if its babbied for thousands of miles.. and then boosted on with full boost.. it'll prolly blow the hell apart
