Hi all

i picked up a 93 CBR900RR
The plan is to strap it to my buggy and hang on. I have a small problem. It won’t run unless the choke is on. Leads me to think there could be a vacuum leak.
sure enough I have found 3 pipes attached to nothing. I have a feeling there is possibly a piece missing somewhere along the lines of a carbon canister or something. What I really need to know is where are these pipes ment to plug into abs what do they do ?
after this if I still have no joy I’ll rip the carbys off and give them a clean.

1: comes from the top of the carbys
2: comes out of the black box that is plugged into the carbys
3: comes out the bottom of the fuel pump

any help would be greatly appreciated.
