Running In Guide - Good or Bad?

Seen in another place, the guide basically says you should have it
mostly run in by 20 miles. He reckons it works well, but there's no
independent proof. Seems to agree with the champ running in method, I
think.

Does it sound right or is it bollocks:

The instructions that came with my Nikasil cylinder kit on my two stroke
only said no more than half throttle for the first 40 minutes.

 

Using the patented Mavis Beacon "Hunt&Peck" Technique, Christofire

"The results are always the same... a dramatic increase in power at all
RPMs."

Compared to what, exactly?

How dramatic?

Well? Well?

Not that I'm looking for a reason to cane the tits of the 1400 on
Saturday, or anything.

Hum. Seen it before somewhere. Everything he says makes sense in
itself and is similar to breaking in two-strokes on a track to a
certain extent from what I can recall. I'd be wary of using that exact
technique on an older air-cooled design like a Guzzi, though.
Assuming that he's right about the honing and other modern engine
details.

Just one trivial detail: he says "thousands of psi" in the combustion
chamber, but I read somewhere that ignition raises combustion pressure
by about 5 times in a petrol engine, so given say an effective CR of
10:1 (WOT) then that's only about 750psi. Yeah, nit picking.

 

My 6R has just ticked past 45,000 and it was run in using the Ade "Take it
easy for the first tankful and then go for it method" and, my sheer
incompetence aside, it's never given me a lick of bother. Even now, after
all of the neglect, missed services and crashes, it still starts every
morning, first time, on the button.

Of course not, and I didn't post it thinking about this, Sweller's
engine woes.

AndyRs plans are a bonus though.

 

Basically he's jimmying on about avoiding bore glazing. All well and
good and I agree with him on that, but I think he's talking bollocks
about the quicky 20-mile run-in process, at least in the long term. For
example, you can run-in a competition engine very quickly, but it's not
intended to do 100,000 miles.

As ever, what use the engine will be put to dictates treatment and
everything is a trade-off for purpose.

Mine's gone tits up because of overheating, probably caused by a shortage
of oil (not enough to lube /and/ cool).

I have a feeling I may know when this occurred and it may involve the M27.

It's run ok for a year before the cam followers gave up the ghost so I
may just sling it all back together.

The pistons are 6 thou under spec the bores will get a honing. The crate
is back in the game.

 

We have done this here before and I pointed to this chaps website.
I kinda hold with him though, ish.
Take it real easy for the first tankful then slowly wind it up to the 500
mile service, remembering engines sometimes use a different oil to that
point, then gun it.

Although I don't agree myself, some people think 996's can be fragile. Mine
got this treatment and after the first service was taken for a weekend at
Knockhill track in 25 deg heat (1). It ran flawlessly and quietly until I
sold it with 12K on the clock.

(1) the first and only time they had those temperatures

 

Have you seen the size of the oil cooler on my Bastard12? one of those
should do the trick!

 

Do they have thermostats?

 

No and you don't need one in an oil based system
You can see it here

That engine is quite heavily tuned, runs high compression and it deffo does
not overheat. In addition the 'cooler looks Pos as ****.
