Hey guys, i was just hoping somebody had had the same problems. I am baffled. Let me recap what i put in the first post. The alignment of both bikes is spot on I checked it with a straight edge on each bike. One bike does have the shitty stock arm and carrier, but all bearings are new. My cub has a round housing carrier. i just dont have a clue here. Everything checks out, but something is wrong. When i adjust my chain, i have somebody sit on it to get it at its tightest point in the travel then adjust so it just has a little play, not tight, but not to sloppy. this is the way ive always done all my bikes. Never had a problem. If this is wrong, let me know i'll try something else.
