Tubes between 1-2 and 3-4 carbs
« on: April 19, 2011, 11:09:11 AM »
When putting the carbs for my 75 750K back together I was perplexed by two tubes coming out of T-joints between 1-2 and 3-4 carbs. I don't think it's in the Clymer manual, and Bike Bandit's microfiche refuses to acknowledge their existence. Part 32 here is on the diagram, but not in the list...

What are these? Where do they go?

They're vents for the fuel line.  They go over the filter housing and down in front of the swing arm where the float bowl overflow lines go.
