I have a set of KB performance 96mm pistons. I recently disassembled most of my engine. The engine was freshly rebuilt (with about 250 miles) however I was having an issue with cyl 3 so I took the engine out.
About 25 miles prior to removing the engine, I stripped the #4 spark plug hole. I replaced it with with a time-sert. I thought that I had done a good job of removing the metal fragments. Once I got the cylinders off, I realized that I missed several metal fragments. What can I do to fix the piston? Is there a DIY fix? Yes, there are some minor gouges on the cylinder wall- I am going to get it honed. Attached image(s)

could you try going in with a dental pick to remove those shards, or are they welded in there now? even if you get the metal out, you are going to want to have the piston checked for roundness and possibly machined and re balanced - which would also mean pulling the other two pistons.
Without having it checked, you could end up re-scoring your cylinder. if you want to go this route, I have 3 used 96mm KB pistons in my shop. I would be happy to sell you one of them for cheap. You would still have to re-balance the other pistons. Zach |
