Do all of the small vent tubes (3 of them) that are on each Mikuni round slider carb need to be run to a catch can? If so, is there a problem with running them to the same catch can that receives the crankcase vent hose? Thanks.
I think a catch can is only need for a crankcase breather tube(s). So that no oil gets on track. I think there isn't concern about carb drain tubes, but Mongo can give you more technical info.

Most people do not vent those with tubing at all. Real crazies like me however do. I run all of mine into the same catch can. Properly arranged and with the right color tubing you can get it to like something right out of Metropolis!
the most important aspect of the vent tubes is to make sure you do not allow them to sit in a low pressure area (compared with the air flow around the rest of the motor). i have all of mine vented to my breather bottle. just some insight. rob.
As they all said above do so if you prefer (I personally would) and while it isn't required to run carb vents to a catch can you probably should - if they need tubes then they probably should go somewhere any fuel coming out won't adversly affect your traction.
