Got a new engine? Want the most power? Read on.

My engine is 25k old and way beyond this, but it might be interesting
reading for those like Champ with a newly built motor and looking for
max HP.

I don't think it's a ginge, but WTF.

[If you break anything it's not my fault, etc.]

Are all rings the same as dykes rings?

 

It is, and it's also bollocks, IIRC from previous discussions from
People Who Know.

Champ has his own running-in methodology, which ISTR makes much more
sense than this one.

 

I've always found it interesting that on all three bikes I've had new, the
'running in' instructions all co-incided with almost exactly the point at
which the engine started to make the power/became interesting.

4.5k on the DL
7.5k on the GSX-R
Can't remember on the SV, but it was the same idea.

I have this suspicion it's about getting used to a new bike, rather than
"saving the engine".

 

In a literal sense, of course.

It still doesn't make it any less of a suspicion though - this is, after
all, the same manual that recommends changing out of second gear at 12mph,
and riding very very slowly if it's wet or windy.

 

Are you saying the running in period was 7500 miles or am I mis-reading
something? All three of my new machines stated ~500 miles.... although
this usually ended up being about 50 ;-)

So, what is champ's super special running in method then?

 

RPM

Durrrrr. RPM, not distance!

 

Mine made more of a brummmmmm noise.

Are you saying that you thrashed the arse off the Fazer I bought from
you?

You complete bastard!!

I ran the CBR in according to the handbook (5k rpm up to 600 miles, 7k
up to 1000 miles). It turned 80,000 miles at the weekend [1] and doesn't
use any oil.

[1] Dundee, Braemar, Aviemore, Fort William, Oban, Lochgilphead, Inverary,
Tyndrum, Perth, home - 400 miles. Nice.

Either way it is still utter fucking bollox.

But I had the other 79k miles (and counting) to look forward to ;-)

Not entirely bollox, but nothing new on that site either.
It was done much better in 1981 by A. Graham Bell.

I've had three new bikes over the years and in each case I was very
cautious as I rode them off the forecourt. An hour or so of chugging
the long way round home and an oil change and then 500 miles/first
service of "**** me it is surprising how quick you can go and still stay
inside the guidelines, mostly."

I rather felt that over two or three rides chosen to stress the bike the
way I wanted it stressed going in 50 or 100 mile increments of beanage
up to the first service point was about right. By then I had become as
familiar as I was ever going to be with the bikes and was riding them
accordingly.

No, but if you've got an R1200GS going cheap let me know!
BGF.

 

How do they run in aircraft engines? Just out of interest....

 

Sounds like a marketable product. Precision running in, to release the
power... and so on....

 

Meh, it works doesn't it? I didnt thrash it till it got to about 500
or so, but then I didn't treat it like a ming vase either (I cant spell
faberge egg)

Half the people say you're blow it up if you rev it, and the other half
say you'll polish/glaze/whatever the cylinders if you pootle around at
30 mph everywhere. So, I just rode the damn thing.
