I've been having the same problem.
I just ordered the Odyssey charger and will give that a try. But I have to ask, how do you ever take a road trip, or even ride to work in cool weather? Am I doomed to having to carry a charger and extension cord with me everywhere? It seems that if you can't count on the bike starting in mild weather without keeping it plugged in all the time, then it really isn't good for much.
Right now I kind of have the feeling I bought a $13,000 piece of yard art. The dealer had it for a solid month and said they couldn't recreate the problem. Picked it up, the next day it wouldn't start again. Took it to another shop and where they had it for two weeks and tell me that the charge voltage is a little low, but not low enough it should be a problem, and can't tell me why it is low in any case. I will pick it up tomorrow and wait until I get the new charger to see what happens.
Anyway, I love the bike when it runs and don't want to seem too negative, but right now I've missed 6 weeks of wonderful riding weather, a vacation road trip I had planned, and still have no confidence that my shiny new bike will start when I need it. It has been in the shop more than on the road since I've owned it and I just don't have a warm fuzzy about it.
