I picked up a pair of 78 CB400 comstars from Ebay and installed them on my 76 cb550. all i had to do was replace some bearings for the axels to fit, and make some spacers to take up the slack. They ride well and look great, but the rear is off center. The sprockets and chain are lined up. the wheel itself is 1/2" to the left when looking at it from behind. Has anyone resolved this situation first hand? Any pointers? My build is posted : Cary nc cb550 Thanks
