Exclamation second time blown HG

I changed my HG a year ago, this time, same circumstances, going WOT 6th gear, in a long staight road.

We where going terminal speed...

and my temp starts going up, stooped the bike and my reservoir is above F mark and I see bubbles....

bike has thinner HG, a degree, and nothing else.

any ideas why this happened again..

last time we checked the head, block, etc.

Im running 2 lean or something????

Add fuel above 12.5 k and slowly ramp down timing to stock values at 14k. Running an engine at high rpm max load puts a lot of heat in the cylinder. Add fuel to cool it down. I have added fuel in the past to get through some knock due to timing, but at high rpm and high load I would just pull the timing. You are not there long enough during normal use to lose too much power.

Are we presuming the temperature started to rise as the head gasket blew or are we assuming the the temperature rising is down to bad FAR & or ignition advance that caused the gasket to blow. But what has happened is the gasket has blown to water jacket (bubbles in expansion tank) second time im not sure what happened the first time to cause a gasket blow but was the head & block checked for level, is it a quality head gasket?

Basics checks:
You torque wrench being true.
Bolt thread and washer lubrication with moly is important.

Thermostat.
Careful after coolant fill, it takes 3-4 cooldown cycles for all air to come out.

I'm building a test to measure delivery rate when fuel pump starts to drop pressure.

So presuming the head was pressure checked & there was absolute visible evidence that was the head gasket itself that has gone twice, was there any indication of burning on the pistons or spark plugs, the pistons normally burn at the front nearest the exhaust valves. Has the gasket gone in the same place twice. The picture attached is of a severe case of running lean its burned a chunk of piston away.

I would check to see what the compression has risen to with the thinner gasket.
