I just picked up my kit today.. Sold the t-nytro actually stoked to ride this thing this season.. Hey goodtogo which thermostat did you use? Im running this kit on a 2010 Yz450 I bought a spare air box going to cover the intakes up with outerwear or slp screen and seal the box up hopefully this keeps filter clean, air temp sensor might be okay in box? .. Gonaa run a lean map with the yammi tuner hopefully that helps the over fueling as well
