this past saturday the bike started running poorly, but managed to get me home... i'm leaving out a ton of details. i just plugged into to ibeat expecting to find a fault code, but it turns out to be an internally dislodged negative battery terminal. yes, the battery was secure, i did not rely on the stock mounting method. there was/is a change to the display sequence when the key is turned on... "sel 2" and "fail" no longer display, it goes directly to "sel 1." since "sel 2" was a crappy map, i don't miss that, but i'm concerned about what this change might mean to the system. it's a reflashed ecu.
I'm not sure what the change in the start display is all about, but the Husky EFI bikes don't like running on unfiltered power caused by a bad or disconnected battery. The owners manual states 'never run bike with a battery'. I had a battery fail on me along way from the truck once and was lucky to barrow a battery from a KTM rider.
