Quick question about the 650NK... Purchased mine in October of last year and haven't had any issues until just now. The plastic shroud that covers the exhaust down the bottom at the front of the bike has snapped it's mount on the right hand side of it and when I was taking said shroud off I noticed the top engine mount bolt has come loose and is missing the nut from the left hand side. And in doing so the engine has dropped by about 3mm on the left hand side as the bolt is completely loose and just rattling around not really doing anything. How safe is the bike to ride? I don't think it's been like this for long but I haven't noticed anything strange with the bike so I'm really not sure how long it's been. What is the best way to get the engine to line up again? Would lock tight be the best way to ensure the nut doesn't come off again?
