Project: Break in Dutch machine

I have no experience with LM based motors, RichardE has.
So far the experience is that some engines need more time and sometimes you must not get fooled with the pinch, the first start will always be much easier and the break-in takes only a few tanks.

Roelof: Do you have any experience with LM produced engines and their pinch? I have an engine that has seen 1 hour at 90 degrees, 1 hour at 80 degrees and 3 hours at 70 degrees, but the pinch is still incredible hard... The piston looks a bit like the picture of the OS from earlier in this thread.
The Novarossi's does not behave like that and have much less pinch after 4 hours at 90 degress.
Edit: RPM's was set at 400...

If you have an air compressor it is wise to blow out all the screw holes on the crankcase, from making the screw thread some dirt will stay behind. but no, no filter is needed. When I have to do 2 or 3 engines I will use the same oil, it is clean enough..

The guy behind the original "Dutch break in system" did take down all his stuff but I can not tell you why.
I can not tell exactly about the EBIS but I believe it can go up to 200 degrees celcius, 1000 rpm and it has no load indication. Basically if you let it run for 4 hours or longer it must be OK.
What do you mean with an adjustable load?
The 2nd I made was a 1st start from Richard I finished for a friend when Richard decided to change his design. It is based on a simple transmission motor with a 550 motor at a 400rpm on the output shaft, no rpm control wich is not needed with that rpm. It has still a load indicator and temperature controler. Currently I am working on another 2 based on this same design (see attagement)

Thank you for all the info you've shared and answering my queries.
In regard to the reasons why Break In Dutch removed all his stuff and Fb page - you cannot answer me because - u r under some form of agreement like an NDA to not discuss - or you do not know why he did it ?
Also, any idea why the elaborate "stepper" motor was used? seems a bit over-kill and over complicating things ? How and why did u select the motor you are using? The firm that sells them [ the motors you use ] doesnt ship to USA - meh ....
couldnt one use a brushed or brushless motor to handle this task - say with a older ESC and old spektrum radio + rx to power and adjust speed? sure u might not know exact rpms etc - but ....
Are those motors not strong enough or controllable enough to be used?
the mystery / black box in all this for me - is the controlling mechanism thats being used.

These are questions you should ask in the EBIS topic but I believe the selling price is 600 euro. And yes, several are already shipped to the US

If you did read this topic about my machine, there is a temperature controler that goes up to 115 degrees celcius max but normally to 100 degrees. There is a motor controler and I can adjust it from 0 to max 900rpm after the belt transmission. And yes, I have a load indicator.
