    It's not the air jet or part of used on bigger mikuni's ? which could lead to leaner /detonation :-\

The head shows black divots everywhere(marks were made before combustion), detonation blasts the chamber clear the combuston chamber and piston. Deto also erodes the timing edge of the piston.

I'll near bet it's pre ignition/detonation and the reason the divots in the top of the piston are black is simply because the engine was being ridden hard whilst detonating. Did it have a horrible rattle under load like terrible gudgeon rattle (pinging) and did you keep on the gas whilst it was making such noise? The fragments are bits and pieces of molten metal from the piston crown and cylinder head. Check the port edges also as these can fragment under such conditions.

Detonation will give a blistered surface on the piston crown but it simply cannot create the small, sharp edged divots the Turtle's piston has.
The good thing about telling the truth is that you don't have to remember what you said.

Whatcha reckon we run a book. ;D

1/ bet evident damage is
                  a/ physical, as in a bit broken off and bounced around on top of the piston.

                  b/ pre-ignition/detonation.

2/ Further bets,

if bet for a/ the cause was;
                  a/ little end break up
                  b/ foreign matter
                  c/ big end
                  d/ reed bits
                  e/ carby bits
                  f/ others

if bet for b/ the cause was;
                  a/ ignition timing
                  b/Jetting
                  c/ combination of a/ & b/

or you can bet it was;
                  a/ act of God
                  b/ act of Turtle
                  c/ typical of a female (Kattie in this case :D)

My bet is $10 on Physical and $10 on the little end (and that's the remains of a roller embedded ;))

Turtle is 'house' and gets 10% of all winnings for providing entertainment value  ;D.
