a few '6 beam questions

[Niall]

ok so yours ideally needs that bias valve. All the pipework will be identical to yours so id swap it over then. Alternatively, if your 1.6 beam is not cambered and in good nick, you could take the bars and arb out of the gti one and put them in your 1.4 beam. Less faff with having to swap the pipes and undo old brake unions.
