I just bought a 2008 R3 (new from the dealership) about 6 weeks ago. Loving the bike, but this weekend it got down into the 40's and Monday morning the bike would not start.
Monday night when I came home and it was in the 70's, it started fine. I decided that the battery might have been week from sitting unused for a couple of years, and replaced it with an Odyssey PC545. It seem to start easier, but Tuesday morning with the temp around 60, it would not start again.
So, I just wedged in the PC625 and will see how it does the next couple of days. If that doesn't work, it really needs to go back to the shop and see if something is wrong. I do a lot of Fall/Winter riding, and the bike becomes kind of useless to me if it won't start reliably under 70 degrees.
Keeping it on a charger really isn't an option, because I don't have a garage. It also isn't practical because if I ride to work on a 50 degree day, I want to know that the bike will still start when I'm ready to go home.
Hoping it gets resolved because otherwise I love this thing and am looking forward to putting a lot of miles on it.
