I have a Yamaha U7E. It has an internal throttle made up of three pieces. The throttle tube, the throttle slider, and the cable stopper. I have the tube, and just found the slider on Ebay, but I am missing the cable stopper (yamaha part # 116-26245-00-00). Would anyone happen to know what other Yamaha models I could find this part on? or possibly how to rig a suitable replacement part.
