i have a 89 suzuki lt2320s. when i ride there is a clicking like something is catching on the chain or the rear axle is loose.

Anybody know whats goin on?

 

put it up on stands and check if the axle is loose if it is its time for new rear bairings also look along the chain to look for wear if it is scraping against anything then look where the chain goes to see if anything is there that it might be banging on
