Title: CB550K1 Carb air vent pipes
Post by: Ibby4585 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 are routed stright back towards to battery, where the still air is. I can check lenghts next time I'll be in garage

Ahh ok, do they go over the frame brace and down next to the battery and airbox?

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
