OK... so I just cleaned out the airbox and washed the prefilter again . While reading the manual it says to check Breather Hose Filter, so I am about to take it off and check it but I notice it is pointing up to the Airbox. In the manual its states to make sure the arrow points in the direction of the engine , but it is pointing toward the Airbox .Now this hose comes from the engine [ Crank area , low down ] and runs up to the airbox , and if it is supposed to be pointing towards the engine would not that mean that it would pointing down to the bottom . This is the first time I have had it off and it obviosly came from the factory this way , so I put it back on the way it was . Which way does it point for you guys ?

 

Ok ....dose this mean nobody has checked this filter? Someone must have an idea.....

 

it should point towards the engine

it wont hurt to have it backwards,,,,,just wont filter as well

dont turn it around though,,,,replace it with a new one and put the new one on in the right direction

 

Thanks bing ....

 

I'm not sure if this applies to the 400 but the twins (600/700) had an update that eliminated that filter and puts a slit in the hose to allow built up pressure to release in case of condensation freezing in the hose.
