The last few times I’ve been out riding, I’ve noticed that 4th and 5th will slip under a heavy load. I ride single track and so I’m in 2nd and 3rd and have no slipping in those gears even under heavy load. Its only 4th (which will slip back into 3rd under heavy load sometimes) and 5th gear which feels like it slips into neutral and back out causing a sort of herky-jerky feel. So I took the clutch cover off along with the clutch basket and found some small metallic pieces of metal. While cleaning the metal pieces out I noticed this Could this be my problem??? This is the STOPPER LEVER ASSY that has a small bearing on the end of it. As you can see the bearing is gone and nothing left but the race.
