Bought the CHEAPEST Good condition DRZ400s in Florida!!!!

I started looking for a DRZ400 because Morgan and I are planning a long distance road trip/overlanding trip out in the western part of the US. I wanted to have a back up vehicle just in case and also keep up some motorcycle content while we are on the trip! I bought the bike for $2400 which is a STEAL for a drz400 in this condition (or so I thought) turns out theres a weird knocking sound only when you blip the throttle, other than that it runs great! I still have to figure out where the knocking sound is coming from.
