Honda Recon Starting Issues

I have a Honda Recon 2014 that I have owned now for a little over a year. As long as I start it up every day or so it does fine however if I let it sit for over 5 days it is impossible to start. Have to take it back to the dealer for them to do their magic. Usually, they find nothing wrong except cleaning carb and sometimes changing gas. Have run 87 and 93 with and without ethanol, also have been adding fuel stabilizer to the fuel. Really getting frustrating, have a new Honda that wont start. Help, my grandson wants to ride.
