Changing carb vent hoses

How difficult of a task? Will I have to remove subframe?

I just picked up my bike from the dyno tuner and found they cut all my vent hoses short. Being a street only Supermoto, if like it to remain clean and not spit up on my nice motor.

Any insight is greatly appreciated

The FCR Carb has (2) rights and (2) left vents.

Each side vent is a 'Y' into two hoses.

The preferred method is to put one half of the Y under the tank, and the other down below the swingarm, for each side vent along with the over flow tube

You don't have to remove anything but the seat and tank
