    Replaced my bent titanium valves with these bad boys and have not had to adjust them after 7 rides! Worth the money

    Faction MX Intake Kit

    BARY in UT

    Really mellowed out my 450X

    After having valve issues on a recent trip to Baja I came home and promptly purchased and installed this valve kit. It all went together well and the new valves sealed perfectly in the valve seats. Before installing the kit my bike pulled strong well into the rpm range that I wasn't comfortable taking it to. after installing the kit I can't get it to rev anywhere near that range. It does fine below about 7 rpm but above that it sputters. I think the valves may be floating either due to bad springs or the wrong springs, possibly intended for the titanium valves but I don't know and I have not been able to get Faction MX to answer the phone, respond to an e-mail or return a call and I have tried many times. I would definitely not recommend this valve kit.

    This Kit is worth the money!

    The exhaust on this kit is perfect. Increase exhaust flow and sounds throatier, its not annoying loud. If anything this is the upgrade to get. I am excited to see how the cams are going to do once installed. Amazing how much power this kit increases the RzR. I love it!
