Oh and regards to the K and N, the bloody thing was in up side down!!!!!

hhahahahhahahhahahahahhahahaha.. i didnt think that was possible!!!! shame on prev owner for that one!!
me thinks its time to have a good look see at bits of your bike to see what else its hiding!
dont suppose you can contact previous owner and ask what they have done to it?

That is insane! I can't believe that someone could possibly do that

Might want to strip your carbs and see what's hiding inside
