I've tried several metric and non-metric wrenches and they don't fit the throttle cable nuts

My bikes (2003 and newer) take a 10mm wrench on the nuts down by the carb.

A small crescent wrench (adjustable open end wrench) would also work.

10mm. It is a bit smaller than 7/16" and a bit larger than 3/8", therefore, neither of them work.

+1 on the 10mm

Strange because my 10mm wrench seemed not to fit onto the nuts. I will try again later
