My 96 fe501 got stuck in neutral, i took the clutch cover off and de-burred the star and shifting fork. I noticed that the shaft that tbe clutch slides onto spins freely for 90% of its revolution but then feels slightly tight. If i continue to spin the shaft it frees up but then tightens slighlty at the same point of its revolution. If i try to change gear when the shaft is in its tight spot it wont change, but turn the shaft a little till it frees up and the gear shift starts to work again. Any ideas? All replies greatly appreciated
