Very confused. I put the bike back together last night and it wouldn't start. I heard what i assume the starter spin a couple of times each time I tried to start it. Heard this the first couple of times then after the first couple of times all I hear is a click like something is in a bind? I took it apart to put shims in. I put it in fifth gear and rotate the the wheel around to get TDC. Then I took the cams off to replace the shims. I then I put it all back together in reverse order. I'm confused of what it could be but have a feeling it's the idler boss. Going to take the side over off at church and see I can figure it out from there? any takes on this would be appreicated
