I'm having problems cranking my bike up in the mornings. I just bought my '02 last august and I had no problems...then winter came. When I took it out after a couple of months the bike wouldn't start. I had to walk it to the bike shop (lucky the shop is only a couple of blocks away) then when they put it in the shop it started without them doing anything to it i'm just wondering if its the gas i'm putting in it or is it something else? i put BP gas in it most of the time.
