None of my power sports like ethanol. Especially my 2000 600 polaris. It's to the point in motor work where I don't have to run race gas. Twin pipes, custom airbox, clutching, mild porting, reeds..and on and on...If i put anything other then non-ethanol it pings and makes all sorts of funky noises. My dragon 800 with it having the cleanfire injection has a little plug down by the ecm so I can run ethanol (plugged in) or not (un-plugged). All it does is changes the timing through the ecm and allows it to fire the ethanol and completely fire all the fuel in the jugs. But when I have it unplugged and running non eth fuel (because of the increased timing) it runs 10x better. If i messed with the timing in my 600 to run ethanol fuel, i'm sure it would run better, but with it being so mod, no thanks
. Boat seems to not mind it as much (has a 5.0 chev), jet skii's hate it, dirt bike, well with 15:1 compression outta a 450 honda.....yea I kinda have to run race gas. LOL Lawnmower loves that 110 sunoco from the bike for some reason LMFAO
