get a cheap 10mm opened end wrench and bend the opened end 90 degrees to the body.do the bending in a vise and heat the area to be bent.grip the box end with vise grips and turn.it takes a little practice,but works without removing anything.
You may need to extend the length of that bent 10mm wrench to make the trip past the fuel system and still have something to hang on to.
AC sell a similar specialty tool for the job if you don't have the resources to make your own.
I just pull the airbox and carbs for easy access with standard hand tools.
Stock setting is usually around 50/1 ratio. You could lean down the ratio to 70/1 providing you're using synthetic oil or Blue Marble.
