I would recommend replacing the potentiometer with an actual fixed value resistor once you find an adjustment you like. Measure the resistance of the Pot when it's adjusted property and the wires are removed. Then permanently replace it with an actual resistor of around the same value. Potentiometers value change depending on temperature, wear and contaminates. Vibration could also wreak havoc temporarily changing the value or even creating an open circuit for a millisecond. Plus you don't want to make your motorcycle less reliable or add something else that can easily fail. Fixed resistors are far less effected by temperature, totally water, dust & vibration proof and almost never fail.

If you want adjustability then putting a fixed resistors in parallel with a Pot is a better idea because then if the Pot fails you don't have an open circuit condition.
