After i took off the gear linkage arm and tried to put it back on, the shaft would move in and out. i have to pull it out in order to change gears and bring it into neutral. But the neutral diode will not come on so i have to hold in the clutch whenever i want to start the bike. After i got the bike running i had some serious clutch clatter and tightened the cluth alot to make it go away to the point where there was no freeplay. what is the problem?
