Breaking-in, what to do?

man its a serious debate whether to follow the users guide or to follow
these instructions.

http://www.mototuneusa.com/break_in_secrets.htm


or should I just follow the users guide but give the engine a few hard
accel's and deccel's for good measure.

I don't understand why the maunal would tell you not to push the engine hard
and not seat the rings...

what to do!?

 

If it's an R6, ride it like you stole it. If it's a little old lady touring
bike like a CBR600F4i, WTF do you care HOW it's broken in?

 

This guy sounds like he knows very little physics.


Are you breaking a street bike or race bike? 2 stroke or 4?

I had a quick read of the page in question. I actually found it quite
amusing in a way, because about 10 years ago I was asking exactly the
same question of a fellow A grade road racer who also happened to be a
Kawasaki dealer.

He gave *exactly* the same advice.

I mulled over it and thought, naahhh, he's full of shit. Actually his
comment was that by doing that way you would almost certainly get
between 5-10% extra horsepower, but he would not vouch for the
longevity of the engine. This did not bother him, because at the end
of the season he would put the road gear back on and sell it as a
demo.

Fast forward to 2000 when I bought my ZX6 to go racing on. I thought
about, tnen used a method similar to the factory recommendation, but
with the occaisional rev, and an attempt never to let the motor lug.
As I was running it in on the street this was not easy.

Result: Bike was a little underpowered compared to the spec. I got the
motor blue printed and it improved a little after that. The guy who
blueprinted it said that it looked OK.

Next time: I will probably give this guys method a go on my next bike,
I'm just curious now.

The problem is - when you have forked over the cash, it's just so hard
to go thrash a brand new engine.

YMMV

I read the f4i manual, says " no full throttle or full speed operation, and
no extream acceleration for first 600 miles"
thats about all it says!

 

Honda changed it's maunuals quite a lot a couple of years ago. That was even
true for models that needed update in the manual but were no machine
modifications were done. That tells me they were, and most others still are,
way to carefull in their run in description, only in fear of any thing might
be wrong or to slow down lunatics that otherwise would abuse the egnine and
return it damaged under waranty.
