I need a new fuel selector valve for my 1998 TigerShark. I found one listed for Yamaha, and wonder if I have to do any modification to install it. I am not opposed to doing that, just wondering if I need to order a new mounting nut and knob with the valve.
The threads on mine are about 21.7mm. The shaft is 7.9mm
