I have a 1981 YZ 465 that has excess free play in the swingarm where the shock attaches. When you lift up the rear wheel you can see the movement and hear it click. Has anyone else addressed this? I'm wondering about drilling out the holes bigger and using a sleeve or inserts? I have had no luck finding any kind of kit. Somebody has to have addressed this in the past with the aluminum wear? I do plan on replacing the bolts and whatever else it needs. I cannot upload a picture but could email it somewhere? Thanks for any help or ideas!
