KTM Canada called
Update - I got a call from KTM Canada today after leaving multiple messages over the last 3 months. Apparently they had a massive system issue and have over 500 calls to return. Good news is that KTM is aware of the air box issue and said they have issued a service bulletin to dealers (although I asked at a dealer on Saturday and they didn't know about it) I've got a uni on order - so will bring it in to service as soon as I get the filter and can get an appointment at GP Bikes. I feel better now that I got a call.
