I have a 2005 polaris predator tld. I have installed a k&n air filter...drilled holes in the airbox, i hace an hmf slip on competition series pipe(no quiet core) and a 15t front sprocket... i have heard of guys saying that it needs to be rejetted even after just a k&n. It runs great, idles beautifully but when me and my brothers drag i hold it at wide open throttle and it doesnt seem to have much power at low end rpm's. As soon as it hits mid range rpm's it will throw you back in ur seat all the way untill u hit the rev limiter. I was wondering if this is a jetting problem or is that just how the 500's are. and if i should jet it with the mods.
