My reasoning for left side... I initially had it on the right, but found it was too much coordination to get the throttle just right and hold that while trying to push buttons at the right time. I have it on the left now, inboard of the left controls, would like to move it out, kinda hovering over the left controls while still allowing access to the windshield/high beam switches, but lower than the pictures everybody has...... if that makes sense. The adjustable feature has much promise.
I'm also wishing there was another smaller control pad out there, on/off on the inboard side and sideways set/res toggle switch instead of vertical so you could easily reach it with your thumb.....
