    The filter could be stock, an UNI, Moose, or some other foam filter. I was actually referring to the airbox (not the filter) if there were holes punched into the lid for better airflow. The sticky stuff on it is air filter oil. You can purchase it at any bike shop. Yes, pls keep us posted. We want to be able to hear you tell us how Xcellent the X is to ride!

    Hey guys thought i'd follow up.

    I bought this carb and now it runs even worse and it's brand new... i tried to adjust the air/fuel mixture, it ildes but runs like i have a fouled out plug now, before it just backfired. Not sure if my other carb was jetted different but according to the specs from the one i bought it should've worked fine. i'm lost, i'm gonna bring it in. but thanks again for the help.
    Ok, This may sound strange at first, but bare with me. I was working on my buddies 300cc Artic Cat yesterday (he just bought it) and he had very similar problems. Long story short, we worked on the carb forever only to finally discover that the valves were not adjusted properly (too tight / previous owner). The intake and exhaust valves were hanging open just enough to cause a loss of vaccuum signal at the carb and back-firing out the exhaust on decell. We adjusted the valves, and problem solved. It runs like a champ (hope his valves aren't too burnt)! This may not be your issue, but it's similar enough that I thought I would share so you can pass it along to the shop if they say the carb is ok.

    Cheers,
    William

    well the mechanic found out what was wrong with the brand new carb... the main jet wasn't screwed in, it was lying in the bowl... who would've thought? can't really trust that it's brand new it's ready to go out of the box like it say's i guess...

    but anyways it still backfires and the mechanic thinks it has something to do with the valves so hopefully that's it. i'll follow up again when i find out.

    I noticed lots of back firing on a test ride of my just bought 350X also when shutting off the throttle.I thought this normal on Carburetor bikes myself but will take notice of this when I rebuilt it.
