Bike carbs
Hi
I have bought a 1600 xflow, with bike carbs from a Honda 900 fireblade (i think). I cant seem to figure out how to plumb it into the car as there are
many pipe inlets. Shall I just connect the fuel inlet and leave the rest? Also cant work out how to connect the throttle linkage and cable.
Do I have to lower the fuel pressure as I was running weber dgv 32 before/
Any Help would be much appreciated

The non fuel lines are just air lines (they supply air to behind the diaphragm). You can leave them open to air or (if you want to get fancy connect
them to the air box so they get filtered air). It's worth connecting the small nipples (float chamber overflows) together and directing it away
from the engine. Carbs peeing RON95 over a red hot engine is usually bad 
You'll need to use lower pressure otherwise you'll blow the floats. Best option is to use an in-line bike fuel pump. Some people have
managed to use a car pump with a regulator but others haven't got that set-up to work...

I am using Honda Fireblade carbs on my Skoda Estelle trials car with a Facet fule pump and a Filter King with a pressure regulator (new, ebay, cheap,
nice!!!). The large pipe that exits in the centre of the carbs had a small filter box on it when I got the carbs which I simply left in place.

I tried to use the standard lift pump
with a pressure regulator on my zzr carbs
but the car pump overcame the regulator
and splurted oll over the engine.
The pump from a zx9r mounted at the back, next to the tank sorted them out.

I'm using CBR600 carbs on a 2.0 with the standard pinto fuel pump and the standard pinto 1.8 pressure regulator, no overflow at all.

Bike carbs are designed to use a bike fuel pump so why use a car engine pump fit a bike fuel pump job done

Thanks for the replies guys.
What should the fuel pressure be and can I check it using a compression tester?
Also I can't work out how to do the throttle linkage. Does anyone have a picture of how it should go.
