was helping my son work on his 2014 Yamaha R1 that has a crank/no-start issue. We’ve already replaced the starter, battery, and checked the electrical system, so I moved on to the fuel system.
When I inspected the fuel pump inside the tank, I noticed something odd—there appear to be two O-rings in the same location on the pump assembly. From what I understand, there should only be one sealing O-ring in that spot.
