Was buying this motorcycle a mistake?

Last week I bought a 2007 Honda Cbr600rr from a guy who lives an hour and 30 minutes away from me. This bike has 94xx miles it and was priced at $5500. The guy who previously owned the motorcycle changed the fairings to a matte black and also added a scorpion exhaust. I'm pretty sure the guy said the bike was never dropped, but I later found scratches on top of the one of the mirrors and one of the spools broken. After I brought the bike I drove it to a storage unit and noticed that sometimes when I lean to the left the bike seems to make a clunk noise and it feels like I just hit a rock, but besides that the bike seems to be in good condition. What is really making me doubt is that the guy didn't give the toolkit, the owners manual, and I only got one key. I was so excited and dumb that I didn't realized this until days later? Was getting this bike a mistake?

Don't freak out, its to soon to tell. Just go get it checked out by a mechanic to see if anything is wrong.

You're probably going to be OK. You need to find out what the clunk noise is… It could be a bad bearing, so something else, but you have to find that.
