Hello all. Been working on my 1989 CBR 600 that’s been sitting for a decade. I took apart the carbs and during reinstallment, I noticed these tubes that I can’t seem to find out where they go. Any help? Thanks in advance.

 

Looks like they go into the bottom of the air filter assembly

See where bottom end of those tubes connect. Might be reference air-pressure/vacuum signal for carbs.

 

When you put the first part of the air filter in you will see two nipples in the back the tubes slide in and should have some small clamps on the tubes to hold them in place
