please ask the dealer to accurately check the engine idle rpm cold and hot to verify it is within factory spec 1100 rpm+/-100rpm. low idle rpm can cause this gear chatter noise.
this test cannot be done by reading the bikes factory tach. it must be checked using an electronic tach accurate to 50 rpm or the HONDA HDS TOOL or HONDA'S DR.H laptop diagnostic system. a good dealer will have either.
