stuck installing air filter

[jam3z]

i bought a second hand pipercross airfilter and one of the holes has been blocked off. not the smaller one (that connects to the top of the rocker cover) but the slightly larger one. i dont know where this one acctually goes so i cant work out why it would have been blocked?
any ideas?

Just leave it blocked up and then put your breather pipe in the other one:y:

Thats what i did. I doesnt matter. As long as you block up the second hole to stop any shit getting in then it will be fine.

but then what u do with the pipe thats supposed to connect to it? surely that pipe goes somewhere and is there for a reason right?

Im not sure why there is 2 holes to be honest mate. But i know that all you need to put on is the breather out the top of the rocker cover.

If you just block it up all will be fine. I put a rubber grommit in mine:y:

Hang on, when you say pipe... Do you mean the little stub that is on the aluminium tube on the air filter?
