No good, it's a shame that I pay so much attention to the break-in process and there are problems anyway. I also heated the chassis with a heat gun. Only bearings for the break in time, I use non-original ones, and then I change them to the original ones, which were with the engine, after about 4 liters. The engine still has a big pinch so I'm hopeful that it will run fine after full break in anyway.
