Thanks for the info.
I'm waiting for a number of parts from Bob Wright so I'll see what arrives before I make further enquires

Hey Stuart,
I obtained the barrel and cam kit from Ian Gowanloch quite some time ago
Cheers, Murray

I have a 604 big bore barrel and piston ex 72 degrees if you are interested, a very rare item.

Does anyone know if the 558cc big bore kit can be fitted to a 350 Saturno engine?

as far as i know it is possible.
But....
In the beginning both the 350 and 500ccm share the same case.
Later on the 500ccm case was somehow reinforced.
You can see this near the rear mounting bolt of the engine
But i suppose this was not the only thing they have done.
The 600ccm case has a bigger hole for the cylinder.
So using a 350ccm case (or a 500ccm) would end up in boring the big hole even bigger to make the cylinder fit.
And you will still have the 'weakest' case of those 3 versions.
So using a 600ccm case might be the better choice.
If i remeber right the rear engine mount bolt is bigger on the 600ccm engines.
So you have to use some kind of thin bushing or make a bigger hole in your frame ;)
What is your plan with the top end?
350ccm head?
Remember the big piston would like to have enough air/mixture to make much power ;)

ciao Joachim

I thought the 350 had smaller crank bearings, but would have to check a parts book to confirm.
If you want to go bigger get a 600 to start with.
