Hi all. I have a 2008 CBR600RR and I like to start my bike up every week or so when I am not riding in the winter. I went out last week to start the bike and could hear the starter was turning much slower than usual which seemed odd as I have not had any starting issues after I charged the battery last year. I got out my battery charger and put it on 2 amps and when I hooked up to the negative terminal I got a big spark which seemed odd as the positive was not hooked up yet. I started the bike a few times and got a backfire each time and the idle was around 400 RPMs. Also the bike was running very rich. Any ideas would be appreciated.
