Is anyone running intake and exhaust HotCams in their 426/450 and still using pump gas? Previously I just had the exhaust HotCam, and the bike ran great on pump gas. Now I have installed the intake cam as well and intend to try it with pump gas to see how it runs. I read an old post by a tuner (STM?) on the Dirt Rider web site, and he was saying because of the design of the combustion chamber, 5 valves etc., that some of the rules of thumb for the SOHC (Husky/Husaberg/KTM style) motors didn't necessarily apply. He was talking specifically about higher compression pistons with the YZF not needing race gas as he had experienced no detonation problems even with Mexican (Pemex) gas. So what do you think, I'm racing Supermoto which is mostly at high RPM, according to Dyno charts that I have seen race gas performance gains are at the low to mid range and doesn't add much, if anything, at the high end. So unless there is a mechanical reason for me to use race gas I don't want to use it.
