In previous threads, I mentioned that the mileage on my '07 wing took a nosedive from the low 40s down to about 28 MPG. I had the bike at the stealer for a month for some warranty repairs. They claimed that they tested the fuel rail pressure, checked the plugs (good), etc. However, there was no evidence of the work on the work order.
I haven't had much of an opportunity to ride since I got the bike back two weeks ago. Last weekend, I rode two up on the twisties and noticed my mileage seemed to be better. So yesterday, I took a longer ride to Santa Cruz (65-70 MPH), up CA 1 to Pescadera and followed Pescadero Creek back to the bay area. I put on about 125 miles and still have nearly half a tank left. Previously, I would have been sucking fumes. So the problem has cleared up.
What can cause this? It would have to be something that would affect mileage without setting off the ECU light. The problem preventing me from starting the bike in gear turned out to be a corroded connector and I have had a few intermittent issues that I suspect to be related to connectors. I understand that this is not an uncommon problem with the Hitachi connectors Honda chose.
I don't know enough about the electrical system related to fuel and ignition to spot likely locations. Any ideas? I'm hoping one of the gurus will have some ideas. I would prefer to make sure the problem is fixed permanently rather than have it reappear later.
Thanks.
