Can am ftw! Horsepower junkie!! ??

Hey y'all! New to the can am world and I didn't realize what I've been missing till now! I've had Hondas and brutes! And ain't no way I'll ever own any other bike again. I have fallen in love with the power and how easy it is to maintenance my (new to me) bike. Only had it a month! 2007 outlander max xt 800! 2600 miles and has been pretty much babied. Reason for joining is I want to learn as much as I can about my gen1 . So I'm gonna start with this; only question I have so far is what can I do to stop the slight miss my bike has. It back fires 1 time when I crank it. And the rpms fluctuate from like 1250 to about 14 or 1500 rpms. Its a steady missfire. So I'm guessing it's a pretty quick fix. Spark plugs, wires, fuel filter etc... Any help would be appreciated! Glad to become apart of this family!
