Recently purchased a 2013 crf450. Has 13.5:1 piston, full yoshi pipes, removed backfire screen. The ecu was never remapped. And he was running vp110/super 1:1 mix. I installed a pim2 from yoshi. My question is, is this fuel ok to run or should I change it up. To throw another wrench into the works, the supply store only had vp-c12 so I mixed that 1:1 and I'll see what happens tomorrow at the track. Any advice/info would be appreciated.
