I use 16-50 gears and 5 gram sliders. Everything I did is below in my signature. The only thing missing is I added some foldable footpegs to the front fairing for comfort.

Looks like it was running rich not lean and that the piston was touching with the stock head and finally failed.

Also, it is an AIRSAL kit which apparently is compatible with the stock head. I doubt that is the reason why. If it were touching I would have definitely heard it even at idle.

Carbon build up usually means rich. Top land on piston crushed indicates interference of some kind with no valve dropped. Maybe slide failed and got injested or cabon buildup came loose.

I'm following a tutorial for installing the BBK. I'd link to it but I'm not sure its allowed.
They say at the end of the tutorial to go for a WOT run with a new plug (to check lean condition). To me this seems trivial... Shouldn't WOT be avoided during "break-in" or is "break-in" not necessary? (aside from the frequent oil changes)

I really don't think you can tell from the color in this case,as it looks like a peice of the piston broke along with a ring which allowed oil into the combustion chamber accounting for all the black. If you read the airsal instructions, I beleive it says a 30 or 35 minute run-in before WOT.Your case is a tough call.Could have even been a defect.If it were me, I'd go with another airsal. They are way better than anything on ebay,And not much more expensive.Whatever you do, watch the temperature carefully, as a lean condition will overheat the cylinder fast.

I've already got the scrappydog kit in. I'm almost done. But what I was asking is the WOT run with a brand new top end. Seems like a bad idea?

as you all know me..i build RACING ENGINES from micro sprint's to raptor-briggs and so on..you never break in a four-stroke at high rpm's. a 2-stroke is differant i rebuild them at the track and hold them wot all the time. a four stroke has a lot more componets in it to fail. first day slow and second day..third day a little more and so on..but at first NO!!!! thanks..buford

I am by no means suggesting you do that. I didn't. Thats just what it said in the airsal instructions. I did run WOT after about 40 miles, and it still runs strong. In fact, it got better as the mileage increased.

It's alliiivveeeeee! Stock air box is on. Sounds good! EDIT: Everything is still running smooth. I drove around just for alittle while at around 25-30mph. I did not pull the throttle WOT even once, but I did go around 1/2 throttle for about a second, and it began to break up badly. I always had this issue with the stock airbox and my main jet. Would it be safe to assume that after 1/2 throttle its actually too rich? Too much fuel thus misfiring? Let me know what you think. Thanks again for helping me through the struggle!

Pull the plug and check.
