92 Polaris Indy 650 Carb conversion? Need help!

mercredi 9 novembre 2016

Hey everyone, so I bought a 92 polaris indy rxl 650 for dirt cheap the other day. The sled came with EFI but was converted to carbs. I have one quick question. He got 3 Mikuni carbs and I'm unsure of where some lines go.

On the far left, breather? vaccum? return?
Middle port is breather
and right should be fuel inlet.
Correct?

Also, this has a fuel pump with vaccum from the crankcase. I'm getting some fuel to the carbs, but not enough from what I see. I will mess with the A/F screw soon. I can't find a diagram for this carb so that's why I'm asking. On the other side, it has a breather port as well. I'm getting a lot of fuel on carb #1 (dripping from fuel bowl) but none on the others from what I see. Also, the tank has a return port on it I believe. How should i hook that up? Thank! :dunno:
