I've got an 03 cr125 frame with ano 04 cr125 engine. Purchased a swingarm bearing kit for an 03, it went together good except installing it on the bike. It wouldn't line up and the collar on the right side sits outside the dust seal 1/8th inch. Did I get wrong bearing kit? A different swingarm than 03? Also what other swingarm will fit my 03 frame and 04 motor?
