My 85 K100 has taken to sputtering and cutting out but not dying - usually in a 30 minute ride this will happen a few times. In the last year I've cleaned the starter, kill switch, & light switch, and it has a new Hall sensor so I know it's not those.
Here are the symptoms, seems like upon acceleration around 3-4k on the odo it starts sputtering and losing power. If I pull in the clutch and gun it I can get it revving again after a few tries. Even when it's sputtering and cutting out, it will idle. I notice sometimes when I just start the bike, the battery light comes on, and goes off when I rev it a little.
Could this be either a bad battery or the alternator?
