Brand new 3BN cylinder

[Louis-DT-WR]

How much is a brand new 3BN cylinder worth to you guys?

[Calum]

With or without the valve?

Seeing as the the 3MB barrels powervalves are not compatible they're fairly useless without one.

[Louis-DT-WR]

Without and what's the difference in the valve?

[Calum]

@Louis-James Different in shape. A 3MB doesn't fit.

[Darty]

Didn't 3BN's run a lower compression ratio?

The Heads do

They also ran a combustion ring which was adverse to performance.

But instead of paying x amount for a 3MB, Mick abbey will correct it for 30 quid.
