There is an inherent problem with the clutches on sportys. They use a steel spring plate with brass rivets and the rivets wear and break out. Tear it down immediately and hope you didn't screw the basket up.
Had the same thing with my 91 FLH. The clutch was acting up also. Took it all apart and found the spring plate in prices. There was a grove worn in the hub. Didn't have money to replace it so I figured I would try to reuse. Works perfect.
