Spinning tire with bike on stand, Looking at chain from side of the bike You can see chain move up and then drop down slightly. If you stand behind bike and look directly down chain toward front sprocket it will move to the side and back straight. Tried new chain and sprockets, Same issue, Almost acts like shaft that front sprocket bolts to is bent slightly causing it to pull tight and move to the side a little. Have you guys ever experienced this, Mtc billet outer basket added to bike over winter, don't know if this could allow output shaft to move in or out causing chain to move to the side slightly. Any Idea's from the experts would be appreciated.
