Yamaha 1300 Tourer - Yamaha 1300 Tourer Fansite

Hi All
Just a note regarding our spark plugs. Just hit the 14000km mark on my bike so I thought it would be a good time to put in some new plugs. Went to a couple auto retailers but had no luck getting any as they do not stock them, so I went to the Yamaha dealer. To my great surprise I was charged $42.00 for two plugs #LMAR7A-9.............I have never paid more than $8.00 dollars each for these on any of my previous Bikes. Can anyone tell me what the deal is with Yamaha. The parts guy there told me they are the only place I can get them. Not sure if I should install them or put them in wife's China Cabinet and just stare at them for awhile.
