I purchased a set of OEM wheels from a fellow memeber and the rear wheel didn't come with a sprocket. ....I thought nothing if it since I already had one so I was curious do I need to rebalance my rim after I put my sprocket on the new wheel. Just to let ya know the wheel being swapped is a magazine wheel and the same size as my OEM wheel on my RGU. Everything the same other than design. Any help would be greatly appreciated. Thank you very much.
