Has anyone tried using starting fluid on those hard to start episodes? I love my 650, but have not tried everything when it comes to hard starting. It has been great during the winter, but on any day it gets a little warm, she gives me a hard time. I'm trying to get this solved for the warmer months. Does any one know of some kind of injector system for starting fluid? If it hasn't been thought of yet, this might be a solution.
