I used to have an M900 and only used super unleaded fuel in it....found it runs better and the carbs didn't 'gum up' the same as if you use E10 fuel....The other thing is to turn off the fuel and run the carbs dry if its going to be left for any length of time between rides Carb jets do block up if left with fuel in them. I also use a fuel stabiliser when the bike is stored .Hope this helps.
