So impressed with my 900 Trail, just one complaint

I’ve had my 2015 900 Trail since last October, but we finally got to put some miles on it in upstate NY over the weekend. We did almost 300 miles on mostly old dirt roads and some tight trails. The performance of the ProStar engine is so much better than the old 800, it really rips. It’s electronically limited to 64 mph, it could do so much more. The ride with the standard shocks is just as good as the 2014 Walker Evans 800 I had. The PXT tires wander on hard pack a bit, I’ll switch to a better tire when they are worn. The only issue I have with it is that the air filter gets dusted up real quick. This was without following anyone, just dust from my own tires. This engine sucks a lot more air than the old 800. What is everyone’s recommendation on a reusable air filter for it? It’s going to get expensive replacing stock filters on this machine. Otherwise I absolutely love it. If anyone is on the fence about trading their old 800 in on the new 900 trail, don’t be it’s far superior.
