Running In..RADICAL OR WHAT

[Fanum]

Ive just been reading this from a link on the yank advriders forum ......goes against the grain and all dealer advice but with the gut urge to twist that right hand just a tad more to feel your new baby go a bit.....and it does sound logical if you read it through.

What do you guys think??

And how pissed off would you be if you'd just completed a by-the book run in period!!!!

I've just run mine in the normal way

I read the details of this site also, it has been around a while.

Couple of things that came to my mind was:

Why would BMW recommend to do it another way if it was so right and secondly if they do red line them in the factory after production, why do you need to "bed" in the piston rings?

I posted up a similar thread, use search under "running in" and you will see some of the suggestions of the board.

Like everything in life. You choose the route and you reap the results. Maybe I am the cautious type. Just my opinon of course.

Running in why bother

running In why bother
Went to the Berlin factory in 1998, and had a tour of the production line, and at the end of the line every bike built is filled with fluids and tested on a dyno cum rolling road, the guy who operates it does the following.

turns the key, thumbs the starter and full throttles the bike in every gear to max revs, when he gets it in top hold it at full throttle for 1 min, thumbs the kill switch. he gets off, bike shoots out into the dismantle and crating dept.


The chief roadtester does the following
turns the key (cold engine), thumbs the starter, first gear and goes, simple.

lucky or not?

I recently bought an Adventure with 236 miles on it so I'm too late anyway!!

that'll leave me to focus on adding auxilliary lights and a louder horn.

But I do agree that you need to give an engine 'some' grief. When I used to run a garage, I found that if you were too gentle during the run-in, the car ended up using loads of fuel and not going very quickly. If you nailed it early on, it ended up being able to accelerate much quicker. Which sounds great. But.......

......I never found out how those engines were behaving with 50,000+ miles on them. Did you buy a car from this man?

What to avoid when running in

What is running in about, most engines today do not really need running in as the materials are far in advance of what they used to be.

The crucial thing to avoid doing when "running in" a new engine is not to labour it, labouring the engine causes the pistons to travel up and down the barrel in a fashion (wobbles rather than straight up and down) that will cause undue wear on the thrust faces and end up with low compression and exessive oil consumption.

In fact labouring an engine should be avoided at all times, with a new engine it is far better to rev it through than to labour it. The problen with the BMW Boxer is that it is so torquey that laziness sets in and labouring it is easily done.

I think that most dealers / retailers do not explain this enough as they probarbly assume that we are know-nothings, runing in instructions are a dealer safety net.

I do think that the red line should be avoided as should sustained high revs, extended revving through the gears to a moderate speed is fine and will not harm a robust engine like the Boxer.
