290 Evo Swing Arm Bearing Play

Featured Replies

Last weekend snow fell here in Denver, so i took my 290 apart and greased all of the pivots. While i had the swingarm pivot bolt nut loose i was holding the swingarm at the axle slots, and i noticed that the swingarm bearings had enough play in them that the swingarm would move side to side at the axle slots 1/4". I realize that trials bikes dont usually roll very fast, but this does not seem ok, !/4" is alot of side to side movement. This movement was axial not side to side at the pivot. After tightening the pivot bolt the play dissapeared or i could not repeat the movment due to the friction of the pinch caused by the tightend pivot bolt. Has anyone else noticed this with their Evo?
