Hey, just a quick question just to make sure I'm doing things right. I took apart my motor realized the piston was smacking my head of my motor which is odd but it was happening... might have tightened the head to much? Anyways ill get that taken care of i believe its 10-12ft pounds of torque to put it down. My crank though I took the casing off to get the chain off to remove my motor completely from my bike and when I tipped my motor a little bit and noticed a bearing and cyclinder looking thing fall out of the hole in the middle of the crank. Is there only one bearing and that cyclinder or two bearings? I was thinking maybe one rolled away. I just wanted to double check b.c. I know everything needs to be perfect. Which order do I put them back in? Ball Bearing then cyclinder?
