If it is reverse shock loading as stated, then that action need to cease. That will knock the teeth off. Kickbacks will cause it too, so timing must be right, and mixture too.
once started, warm up the engine at a relatively low rpm, and avoid blipping the throttle hard until the oil has warmed and thinned to a reasonable viscosity. Never ride hard until it is good and warm.

We have 15 lb. music wire pump springs that relieve quickly on the up-stroke, but the down-stroke of the pumps are unprotected.
We also have the Ace Oiling system mod, but that is proprietary, and requires that the timing cover and all associated oiling system parts are sent in for mods, and the owner would need to increase the flow capacity of the drainback holes in the engine case to prevent oil flooding of the top end from the much higher oil delivery volume. In certain instances, an auxiliary oil return line from the tappet galley to the oil tank was needed to handle the overflow at higher rpms. We don't talk about this much, but our top builds have it.

Oh, very sorry to hear that. :(

Maybe he was able to get it fixed before the actual races?

He is too!

The main ways that pistons get seized are:
1) Too small piston/bore clearance .
2) Bore is tapered from incorrect honing.
3) Riding hard too soon after a cold start.
4) Detonation causing piston overheating.
5) Oil starvation in the crankcase, from various causes.
6) General overheating.

Bit of news on Guys bike ace, I was on the phone with him and he said it seemed like something with the piston let go, possibly some skirt cracked off and wrecked all hell. He is quite dissapointed.
Also told him to order that damned conrod from you ace, he's been holding off as he wanted one and was gonna save on shipping, but this engine has taken some funds, so just mine will be ordered.
Then the bottom end can be assembled and my engine will look like an engine again!

Well, when you are racing, and pushing the limits, sometimes things break. This is to be somewhat expected, but we want things to last long enough to get thru practice, and last thru the race. If it can last that long, you can tear down and refresh whatever may require it between race weekends.
The key is to make it last long enough, and sometimes that is not as easy as it sounds.
