I’m buying a Harley Davidson Tri-Glide Ultra. I’m a left arm amputee. I have the clutch lever figured out by putting in a Rekluse auto-clutch (these things are amazing). The other left hand control I’m trying to figure out is the left turn signal. While cruising, is it possible to let go of the right handlebar/throttle momentarily to activate the left turn signal? There really isn’t enough room on the right handlebar to mount a left turn signal switch.
