While I was changing the air filter on my 2015 NC750X today (which I bought ~2 months ago), I found a piece of plastic just sitting there near the air filter, not attached to anything! It has a bolt and a screw hole, with part number 64508-MGS-B300 and is labeled "Cover L, Cable Under". I can't figure out anywhere that this piece fits, and googling this part only brings up Ebay listings with no clue on where it fits! Anyone have a clue? Here is a picture of the part in question, pulled from an Ebay listing. This one is from an NC700, but it is identical to the one I have and has same part number, so it is a common part between the NC700 and NC750X..
