I have a new hayabusa with about 4000 miles on it.I had the motor oil checked at a 2000 mile oil change & it showed a positive fuel dilution all of the wear metals showed normal anybody out there ever sampled there oil.The only way that I see it getting into motor is from a injector fueling to much ? I'm a little confused ,looking for a place to start any suggestions.I forgot to mention the bike is getting around 45 miles to the gallon & exhaust has just a very very small amount of black when you check it?
