Custom lightened pistons - I reckon the reduction of internal intertia will give your bike an edge. Now you just need to do the other piston too

No damage to the crank? "Just" piston and conrod?

Cranks not out yet... that will be the deciding factor, barrels damaged but on its origional bore and the heads munted but aperantly thats ok.

Duct tape, cable ties and super glue pfffft, what is really required here is some good old holts piston sealer if some one has a tube laying around

Looks like you have a few busy nights ahead of you, have fun.

Cool jigsaw puzzle! How many pieces in that puppy?

Looking at those piston skirts makes me think oil starvation.

Yes.

It seems YOU didn't do the writing on those sheets your ex-engine is sitting on.

OK... the issue, well its farked as we have come to understand, but why is this???

a couple of things come to attention, 1st and up most it seems the right hand pot was running very lean, this causing a extreamly hot situation, lean means power, but it also means meltdown.

Now I found the idle jet was blocked, what this means is the idle jet being a size 20 and the main jet being size 220 then all up theres 240 sizes, with 20 left and 20 is a big number then the pot on the right was at 220 whic means rather a lean fule mix than it needs.
I run pre mix so a lack of oil wouldent have been the problem and had I not mixed in the oil then the left pot would have been dry aswell.

Now crank spreading may have been a factor but unlikely, I know the right pot when last checked was at its max tollarance, but its usually only the left side that goes in this case. To much side ways movment can generate a lot of heat starting the failing process, but in the opions I have gained its more likely a lean fuel mix that caused this catestrophic failer... and me new pistons, rings, rebore, gasgets, head repaires and crank over 1g
