Any help appreciated - Diagnostic/Recommendation? Suzuki GSX 1100

Hey! I'm hoping the vast knowledge you guys share may be able to assist/help me. I will state now, mechanically, I'm really not the best (At least, on old school bikes ironically). I'm happy to get stuck in, and I learn very quickly, but my knowledge of motorbikes and fixing them as of the moment is rather lacklustre, hence me being here to ask a few questions! I do apologise for any stupid questions in advance (Just keen to learn more) I recently inherited

Yeah, I've got it getting hard recovered back to them tomorrow to go back through her. I want to trust them (They have a ton of reviews, work on classic bikes all the time) but at the same point, they told me she was finished and then all this. I also don't get how they can remove the entire top end but not even give the cooling fins a wipe down? I appreciate everyones responses here though. I'll be sure to post a bunch of pictures beforehand, and once I get her returned.
