I put my '06 Wing (bought it new, now has 50,000 miles) in the shop Thursday because my fuel consumption has gone up over the last 3 or 4 tanks. Generally, I get about 200 miles to a tank, the way I ride. Over the last few tanks I've started to get maybe 175. Had the air filter changed and the plugs. Regular stuff. Bike runs great, no smoke. Mechanic finally concluded that it has 55deg. crank advance and it is only supposed to have 52. I said, "Well, just adjust it." Apparently it doesn't work that way anymore. He said the problem could be one of three things: Crank Position Sensor, Cam Position Sensor or the actual ECM (brain). And apparently these components cannot be checked. I inquired as to what they do when this happens and he replied that they just change parts. Can you say "costly"? They are going to check with Honda before they do anything. Any thoughts? Similar experiences? Would 3 degrees make that much of a difference? I know stuff goes bad, byt all of a sudden like that? And at 50k?
