would a set of Wingleader Floorboards off of a GL1100 I be modded (easily) to work with a 78 CX500? more importantly what would need to be done to make the Heal Toe shifter work?
I don't think you would have so much trouble with the mounting long as you can weld. The problem, I imagine, would be when you try to jimmy rig a system to push our shifter, since our shifters are mounted laterally not longitudinally, although this difference is transparent while we ride, it means we can't really adjust forward-back without bending stuff!
you'd have to use a second lever to move the end of the gearshift selector, with the other end attached to your movement end of the heel-toe shifter, which I imagine would be possible...but difficult..
