You have a "570" engine and you're running an HMF slip on pipe? Jetting isn't a "mod" to be listed with things like big bore kits, we pretty much assume you'd have to do that to make the bike run. So mentioning it is a clear indication you aren't terribly experienced with this kind of thing, which is only confirmed when you bother mentioning that you changed a sprocket. And when you've spent a few grand on a build, the brand of the air filter is usually not all that important.well lets see that guy problly cant drive for shit and if i wanted to i would blow ur lil raptor away with my 07 polaris outlaw 525irs with k & n hmf slip on and JD jetting with a big bore kit making it a 570 ktm power house with 83 hp and 116 mph 15 tooth sprocket.
Assuming for a moment you actually have an 83hp Polaris it's clear to me from your list of mods, your sentence structure, and registering on a rival machine forum only to resurrect a 3 year old thread that you don't have the mental hp to match your ATV.
To those of you who stumble across this thread, I suggest we don't feed the troll.
