I'm am getting the Big Gun EVO R for my 05 CRF450R. I need a little help with jetting. The website says no jetting required, but I want to make sure. All the jetting is stock, only three rides on the bike. I live in Phoenix and the weather is starting to cool off. It's been getting up to the 80's for the high. Any help is appreciated since I don't have a lot of experience with 4-stroke carbs.
