Perhaps the cam chain is worn, my bike has similar mileage and a few weeks back I had the the carbs off and took the opportunity to remove the cam chain tensioner to get an idea of chain wear, there was 3 ratchet tooth segments of adjustment left on the tensioning rod, so it's time for a new one soon. I've read on here that the chain can become a bit noisy just before the tensioner automatically clicks up another tooth to retension the chain.
