Hello all! I recently picked up a 2007 919 and it ran fine for the first two days of having it. On the third I put 91 Octane gas in it and for some reason that's when the problems started.
Here are the list of problems I've had so far:
-Idles roughly sometimes, normal the other times
-Will sometimes die when stopped or coming to a stop
-when I turn the bike on the gauges sweep and I'll hear the fuel pump, but the fuel pump sounds odd
-the gauges will sometimes reset like I'm turning the bike on when I have the ignition already on (bike not started yet) or when I'm riding or just moving it around.
-The FI light comes on and stays on for about 7-10 seconds then disappears.
Another thing is that the day I got it the battery it had died so I put in the one from my Ninja 300 and it worked fine for the first two days and I'm not sure if that has something to do with it. It does not have a power commander. I also noticed that it crackles and backfires a lot and it does have a Danmoto carbon exhaust on it, but I've never hear a bike that sounded like that. So I'm not sure if's it the battery causing the problems or if the ECU has gone bad. Thanks for any help.
