hi have an 80 xt 250 3y3 and it has just failed on excessive play at bottom shock (where it meets the swingarm) i am worried that this is incorrect as it is just a shaft with cotter pin that threads through the holes in swingarm..? bushings and shock eye bushings are sound am worried even if i replace swingarm it will still be the same if designed that way? (and could not shift the shaft for all the heaving in the world) if anyone has a chance to rock the swing arm on their xt and see if there is any movement at bottom of shock it would solve a big mystery for me many thanks and erm..hello there JJ
