What size allen wrench is it to loosen the 4 clamps that hold the air cleaner housing to the air intake runners on a newer Apex or Attak? I found some really long metric allen wrenches at a local hardware store but I can't remember what size I need.
-------Mukwonago Yamaha had the answer ...... 4 mm.
