ello ello from the uk

ive just purchased a pulse adrenaline from someone for really cheap its a 2008 model and was hoping you guys be able to get it running again, I am mechanicly minded just not with bikes, so dont know what im looking for with potential problems but am good with a spanner, the previous owner was complainin of a knocking sound but that might be the exhaust where it joins to front as I have found out it is loose as hell, if its not my exhaust, what could it be in the bottom end of engine? I have read that a clutch pin snaps in them? or a valve gone?

will upload a picture when I get the chance ;) she has 10,000 miles on the clock and doesnt look to bad, I have a brand new set of fairings in the post, going to steam clean engine and frame, wire brush the little bits of rust and treat with rustoleum and repaint will look tidy then
I have heard of engine change with suzuki but no definite yes on internet to confirm or knowledge of what needs to be changed to accomadate the engine

happy biking guys :)
