Trailmaster noise
 

Fairly new to karting and recently bought an almost new Trailmaster 150 XRX. Rode it a few times with no unusual noises but the last two rides I noticed a loud banging type noise when going over very rough ground. I sounds like it coming from the right rear side but I'm not positive about this. I know this is kind of vague but it's hard to describe except I can say it's loud. Everything seems tight when we look at it. Any thoughts? Thanks.
