Big bang engines

[Smitty]

oh yeah it makes sense.

its just that i've got this image in my head of when i replaced the head gasket that the pistons were grouped in pairs.

Vince
they are..!
pistons in a straight 6 rise and fall in pairs
one piston will be rising up, compressing the air/fuel mixture
which is ignited at top dead centre (when the piston gets there)
and
the other piston will be rising up..pushing the burnt gases
out the exhaust

Mario wondered : I wonder about Aust and the US if anyone tried it ?

I was at TKA a while back, and I spied a factory crank that looked very similar to my own dearly departed piece. I asked one of the guys about it, and he said that it was a ZXR crank made by the factory to run as a big bang motor. Apparently it sounded like a Ducati, but the vibration was unbelievable. He didn't mention durability, but one assumes that it wasn't tested long enough (or perhaps hard enough) for trnasmission problems to show up.

Cheers,

I think Ducati does big bang on the V4, firing them as a V2.
