Breather hoses, and what they do

2007 Grizzly 700

So I just found out that I had some breather hoses disconnected. For the last year, at the least.

The hose from my roll over valve was connected to the air filter case, at the point where the throttle body hose should have been connected. The throttle body hose was just open.

Not sure if the rollover valve even worked, I can't blow through it. I was replacing it with a fuel filter when I found all of this.

What issues could this have been causing, if any?

Doesn't sound like anything is wrong with your bike, was it a year since you had it the shop for the last service? If so, service'er again and ride on.

I had it in the shop last year because the timing chain broke. I guess they put it back together wrong.

The rollover valves is vent to the atmosphere.
It is important that the TB hose terminates up by the handle bars in the hose rack above the EPS controller compartment

That's not what the service manual schematic shows.

Thanks for the info.
That connection must have been eliminated in 2009.
My FSM covers 2009-2013.
I also have FSM's for 2016-18 grizzlies and 2016-18 Kodiaks, in all of these FSM's the throttle body vent hose terminates up near the handle bars in the vent hose rack.
