I thought carbs from a 1L bike would be too big to work on an A-series of any kind?

A mate on here had 600cc bike carbs on a standard 300000km a12 and didnt need to change jetting or anything. They were keihin CVK's though, not sure on bore size.

Does anyone know what hose you can use to join the carbs to your manifold that wont melt or swell when it gets a bit of petrol on it? So far I've heard radiator hose is #OOPS#e and blue silicone intake hose is worse.

Don't forget you will need a fuel regulator to wind down the pressure to about 2 pound (can't remember the value I was told but it was lower than a regular carb) as the carbs are originally gravity fed.
