Cant agree more!!!
All my bikes have never been babyed and ridden with WOT and vary engine loads
they never used oil and made good power!
i think the tolerances on engines now days are so good it not neccesary
but the oil change is crucial.

The rings are seated well before 1000mi.
Once the rings are seated there's no point "babying" the car, it's not going to change anything.
I think it's more of an excuse to not stand behind your work. If something goes wrong, the shop could always say "you didn't break it in properly, it's your fault"
Good post Dave! I never understood the 1000mi "break in", but it's good to hear it from you.

Rings are seated within the first 20 miles. Its actually not good to run light loads like most suggest. You need to run some boost through the motor to get the rings to seal almost immediately. I didnt switch out to dino oil, so Im hoping I still got a good seal on my rings. I did run boost through it and drive it like I normally would however.
Ive never believed in the "break it in easy" method. There is a reason why some cars run stronger then others, make more power with same mods, etc. Its the method of break in imho.

it's true..
when i got my e7 back in 01 it was slightly faster than other stock e7's
I contributed that to the fact that I hammered it as soon as I got it..
no "babying" whatsoever

I Agree 100%
Most exotic cars never see 1,000 miles.
We have a $180,000 Porsche turbo convert in our shop getting Stage II now which has 157 miles. No way that car will be driven anywhere but on the dyno.
When you have a 1000 up evo like mine break in is not feasable.
Of course a short break is not going to hurt anything but your pysche.

Just for kicks I did some research on how the Porsche turbo engines are made
First - one guy builds each motor from start to finish by hand
(Just like Buschur)
Second - the engine is dynoed right away
(just like Buschur)
Interesting how great minds think alike

Once the engines are built, they are fitted into a tray with coolant lines and a fuel line. The motor is then hooked up to the Dyno in a sound proof room, and put through the paces for 30 minutes. Porsche refers to this as the “Hot Test”. The engine must produce at least 100% of it’s rated horsepower, or it is unacceptable. How is that for a quality commitment?!? We saw rows and rows of engine trays, with hot coolant still in them from the multiple Hot Test. It is mind boggling to think of how much cumulative horsepower was in that engine assembly room. It would make any racer giddy with excitement!

so im almost set on droping new pistons and rods in my motor, whats the best way to "break in" the new rings?
reg non synthetic 10w30 oil for about 500 miles
then change oil and repeat for another few hundred with non synthetic?
should i throw some boost at it right away? not WOT but like 5-10psi?
also i have alky, should i disconect my alky?

Should you run spring pressure for a while, like at least 50mi or something before turning it up?
My 4g64 doesn't have squirters built in, how will that affect the rings setting in?

ive assembled a few honda motors and when i send a block to the machine shop
jg engine dynamics he does a race hone on it and it breaks in a little while
the cars usually go from turning the last bolt to the dyno.
