Easyryder, Yeah the 300 miles on the tank was 75% hghway and 25% city and was still some full throttle runs in there. Mostly I ride about 50/50 city and highway and I still average about 240 on my stock 6gal tank. I do know the SE254E cam's have a funky grind on them, almost looks like they are designed to run on crappy fuel, but i did pick up good power across the entire rpm band. they are very close to the 255 cams but they don't fall on thier face as much above 4K rpms. In a heads up race the 254e cams will beat the 255 cams, but yeah not sure why you're barely getting over 200 mi on a tank. I do ride aggressive and still turn great mpgs!
