CB550K1 Carb air vent pipes
« on: November 23, 2020, 09:09:50 AM »
I'm at the final bit of getting my cb550 started for the first time since 1984! The carbs will be going on next week but I'm short of the air vent pipes. I will make some up myself but can anyone tell me how long they should be and where they route please?

Cheers
Kris

They go practically horizontally. I'll take pic of them. But maybe they are also shown in HSM?

It is something like this (red line). Both pipes are joined together by plastic clips

330x3,5mm, the latter being the internal Ø.
