So I have a set of used 126 barrels (freshly honed) and pistons 77mm new rings all in great shape I was going to use on my 500 but have now decided to go with new larger pistons and barrels 82mm so along with my recently acquired ZFD 30/24 which is prob gonna be to small for me to use. If anyone is interested make me an offer for the lot or one or the other. More info or pics em me


Cheers

Morning Rizzo;
Before you get rid of your '650' barrels and pistons, have you managed to obtain a Fiat 126 crank-case (and gear-box bell-housing)? From what I remember from my time at Radbourn Racing, the 500 crankcase can't be bored out to take any bigger than 650 barrels---you will end up with no sealing ring if you do.

Yeh im sorted l bought a complete 126
Cheers
