I am thinking of adding the same mixture to my 02 XR250R fuel that I add to my Evinrude 75HP boat engine. I usually put an appropriately measured amount of Seafoam, Stabile ethanol treatment, and carb and fuel injector cleaner to the gas. I am going to run either 91 or 93 octane fuel, plus the mixture of additives listed about to the bike before going on a ride. What do y'all think? Should I just run straight gasoline? I don't want to cause any harm to the bike. Let me know.
