Driving on the motorway, holding the throttle - your hands will get tired. To solve this I had to build something to hold it in place but jet allow some adjustment of the throttle.

I'm a poor man and I have to doit my self. I could have bought a BrakeAway Motorcycle Cruise Control

I just hacked it, no real plan just did one bit at a time. then moved on to the next. I hade a list of functions, thumb to turn it ON, trigger finger or front brake lever to turn it OFF.
