You dont have to sign up. Sheesh man. Im loosing my patience.
They ask you if you want to sign up or you just want to view the pics. You click on free which means you dont want to signup.

THats the funny thing when I heard about this engine Deto was the first thing that poped into my mind. But the pistons show no sign of deto. THe crowns are smmoth as a babbys bottom. And we know deto very well from the bikes.

detonation, and I'm talking dirty raunchy hardcore porno detonation.

tops of the broken pistons look like they were beat on with a mallet.

Ok I didnt want to color the inputs with my views but shouldnt it be the Exhaust valve that goes first. Instead the intake went.
It looks to me like the intake valve hit the piston braking it.
Which then resulted in the skirt failing.
Also the piston seems to have a basic design flaw. Instead of holes driled for the oil to return. They have cut a huge slot seriouslly weakennig the piston.
I could be wrong so was asking for inputs.
Deto would mean some sign. i.e. rat bite marks. Ali on the plugs nothing.

I cant afford new cast pistons so looking for a match from some old 2 valve Bikes pistons. On Egay.
