I find the Honda dealers to be extreme at price gouging. I've told this story before, I needed a DR8 (fairly standard bike plug) that sells in a 2 pack at CTC for about $7, and a M5x16 bolt that sells for about $1 at any hardware store. I was running late and the local Honda Powerhouse dealer was the only place I could get to when I needed these parts. They charged me $13 for 1 NKG spark plug (packaged in a red Honda box, and $4 for an M5 bolt. $20 bucks didn't kill me, but paying 4x the normal retail price annoyed me.
Recently I went there to get a carb kit and air filter for my little Honda gennie -- $67 for the carb kit and and $27 for the filter -- out the door for $110. I choked then went to Amazon where I got a new aftermarket kit that included a carb, air filter, gas filter, gaskets, plug, gas line for $26 including tax, delivered in 6 hours to my door. My gennie runs like a champ.
