I have a 77 flh and had the trans rebuilt 6000mi ago, the mainshaft was replaced but the bike never shifted properly the clutch dragged and now it will not release at all . I took off the inspection cover and it looks like the whole clutch is wobbling, it is not loose but it appears that the main shaft is bent, any body ever see something like this before, can a shaft like that bend under ,normal use or could it have been bent when they installed it ?
