oakley, calif.
Piicking up new fe450... any suggestions other than good common sensewhile running in?...Thanx
 
Ragman,

I asume you know how a high-performance engine want´s to be treated, right?
Some engine tuners say: ride it like you stole it! - Right from the beginning
Performance will be better, but the total engine (bearing) lifetime is shorter...

So, if you compete in Racing you know what to do
if you use it just for "fun", it´s up to you

Regards
 
hey Gokai134...know the expression well...I'm getting older and slower but like to show the other guy a wheel now and then...pretty much know what to do...thanks for your thoughts!
 
This is the way that I do it.

This is straight out of the owners manual for the 04 model. I believe that this is the best way to break in a new motor, and keep from breaking it. I have run in quite a few motors in my time and have used basically the same method for alll of them, and they seem to last a good long time. I went 20 hours before I went flat out across a dry lake bed. And I could feel the motor getting better and better all the way up to 25 hours. My motor now has 185 hours on it, and other than a water pump seal and just recently at 182 hours a new set of cam followers.

Also, check the valves at 3 hours, then again @ 10 just to be sure. After that they won't move much.


RUNNING IN THE HUSABERG MODELS
Even very precisely machined sections of engine components
have rougher surfaces than components which have
been sliding across one another for quite some time.
Therefore, every engine needs to be broken in.
For this reason, do not load the engine more than 50% of
its capacity during the first 3 operating hours. Besides, the
engine speed must not exceed 7000 rpm. Avoid going fullthrottle!
In the following 12 operating hours, you may load the
engine up to 75% of its capacity. Use the motorcycle on
various types of terrain (road, easy off-road trails).

CAUTION: The Husaberg models were uncompromisingly
designed for off-road competition purposes
only. “On the road“ approved models FC/FE
are only allowed on public roads in the original
homologated (throttled) version. Avoid extended
on-road rides at full throttle.
 
What are your thoughts on a re-built motor. NSman is shipping my 550 motor back to me today with new main bearings and piston.

I will be breaking it in on the ice tomorrow. The temperature will be around -5 degrees celcius.
 
Interesting article. It definitely contradicts information that I have received from others recently. The comments on oil choice for break-in are also interesting.

Now the challenge is to try and decide who to believe!
 
I've been using the mototune method for years and I've never had an engine issue yet be it 4-stroke or 2-stroke.
 
oil?

i ran mineral (aka the shell equiv of delo400) to break my motor in, did the first oil change after 1 hour then every 3 or so hours there after. I have only just swaped to motul 300v now after 50 hours and 15 oil changes later.
regardless of run in method i think many people go synthetic to soon.
 
synthetic too soon !

as an exercise i used synthetic [ amsoil 10 w 40 ] in my $ 3500.00 aus rebuilt motor .

this motor is not a husaberg , it has a stroker crank , big bore , JE piston , wild cams , **** in yer pants port job , over size valves , h/d valve springs , ETC .

mototune method and after 2000 klm it has full compression . the 1st 1000 klm it was gutless ,so it took 2000 klm to come alive .
