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)

If you have a local bug shop, they will have the studs you need.
Go over the engine with a fine toothed comb after you have totally gotten over it falling in the first place. You want to be looking for cracks in your heads, cylinders, and engine case. Needless to say, when you put it back together you are going to want to check compression and leak. But before you put it back together take a solid afternoon and inspect everything. Cracked crank or con rod is also possible depending how it fell. Will probably be fine, but crank failure during operation could grenade the engine. I have owned three HF engine stands. All three worked exactly as I expected them to, though two of them were used to build a rotesserie and were heavily modified. Zach |
