Lean, Lean Lean!!!!!!!!! At some point that was the cause of the broken land! It may not be lean right now, but it has been! The color of the valves also suggest this-

The only KB piston I have ever seen do this was detonating like crazy prior to the event, BUT generally detonation causes this on the spark plug side of the piston, not the under side. My guess would be that the top ring became damaged and was allowing some combustion past it, the ring land can't take that very well at all. Yet again Dave breaks something better than anyone else- even us!

FYI- we have now used over 1,000 sets of these pistons (in complete engines and kits) and have never QC'd one piston that had a faulty ring land, out of those 1K sets. I have the sheet where I personally inspected these parts that Dave used just in case his bad luck came back to haunt us all again.

Dave, you know the routine- box it all up and disperse parts to Charles and myself, we'll take care of you again. I can match you up a piston ASAP and Charles can get the plating repaired.

Some people with a nasty sense of humor are getting a real kick out of Dave having all these problems with these cylinders and my parts and it's starting to really piss me off. We have supported Dave throughout this excursion better than most companies would ever dream of- this latest hiccup will easily put LN Engineering and myself over the 5K$ point in component replacement, shipping and the like. Laugh all you want ass holes, we ARE supporting the products that we have offered to Dave and we are doing so without him demanding such replacements- he shouldn't have to!

Dave has been great to deal with on this and while some of you get a kick out of seeing our stuff fail, don't wish the bad luck on a great guy like Dave any longer- spit in our faces personally, don't catch him in the cross fire.

Dave, I want that engine at my shop. (He didn't have to ASK for that either)
