I just bought a yz 450f and I was wondering how much air should be coming out of the air vent tube?

They blow out a lot of air, don't worry. Now, if your header glows red.... :thumbsup:

Close to 450cc of air at a low idle. Then it should get sucked back in. The piston pushes the same amount of air out from under it as it does on top.
