It’s me again, I’m slowly working my way through my current project. Now the engine is on it, I’ve found that a piston ring is crumbling and has cut quite a few quilts into the upper piston edge. think that the part would run with new rings and some files until Katmandu, but still wants to rebuild the cylinder. 1. Which service provider, who also sends, is recommending? 2. Is there the possibility to glue a cooling rib again? 3. Many drill the Stand up and go on M8. Should you do that right away or rather try to freeze them out and get new ones in? 4. How do I measure the piston? Is there enough of a slide lesson? And yes: I send you a side cover picture 😉 LG Usch
