What do I do with this valve that I removed hoses 1,2 & 3 from? Its got some solenoid or something electrical connected on the other end... Do I just leave it plugged in or remove it or what? I have 02 Cali model

 

Get rid of it

 

What does it do? The wire is still connected and I bolted the piece back up because the 2 Phillips head screws are stripped

 

The wires operate the solenoid to open or close either allowing crankcase air to circulate through the airbox. Disconnecting it won't trip a light or anything and with all the hoses now going through the T-fitting the whole assembly just becomes useless.

Here is some more information on it. Just scroll down a little. https://cbrforum.com/forum/f4i-main-...-sensor-62786/

 

Ooh awesome, I was curious because before I disconnected it when I would turn the bike off I thought I heard a buzzing sounds once then another time it shoved like a whoosh sound lol
