First, do you know what viscosity oil was used at the first service? If the dealer put in a 20W50 or something thereabout this might result in noise. Worth checking and or asking the dealer. A long shot I know but sometimes we need to look at the obvious before tearing into the engine. Also, would not hurt to top the oil up to the proper level and run the bike for a few to see if the problem goes away.
