Another post on bad batterys made me wonder could I push start my M2 if I had to? I assume Id want to try it in a higher gear any ideas? | ||

Yes, you can push start an M2. Take a running start and instead of stepping down to first, pull up to 2nd and pop the clutch. Repeat as necessary. I did this when my stator failed and the battery drained to the point where it couldn't turn the starter - it still had enough juice to fire the plugs, though. However, I was not able to push start an injected Fatboy that had a low battery. I'm not sure an injected bike would push start at all unless the battery had a full charge. | ||

If the battery is utterly, terminatably and totally devoid of juice, you can push all day to no avail. They are rarely that dead. Use 2nd gear like Dj said. I don't know about FI bikes - never had one or had to push start one. If you can turn off the headlight before you start pushing, but with power to the ignition, that will help too. AL | ||

I wasn't able to when my most recent battery died. The battery has to be good enough to prime the fuel line. Mine sure wasn't  Carbs don't care one way or another. If air is going through, fuel will be added. | ||

You can definitly push start an M2. It helps to be going down hill.  | ||

If I understand correctly there is a threshold amount of voltage needed to operate most EFI systems, and if you don't get that voltage you get nada. | ||

Helps if you give a nice bounce on the seat when you let out the clutch.And you can jump FI bikes as I had to do my Triumph one day. | ||

An Fi bike with a completely dead battery will start , provided you get it going fast enough on dry pavement. A non FI bike should be easier (carbs don't care about the battery right?). I was able to bump start the 01 x1 after leaving the key / ignition on for 10 hrs straight (guess what I forgot to do going into work). You'll need to use 2nd gear and like FMJ said, bounce on the seat as you let out the clutch. This is one time where extra weight helps! | ||

You can't push-start an M2 with a dead battery when it's parked outside a Wisconsin bar crowded with race fans from RoadAmerica. Don't ask me how I know this--ask Bomber! But if the reason it won't start with the button is something un-related to low battery voltage, it'll push nicely. Second gear, 8 or 10 giant steps, run-n-bump. No sweat. Unless, of course, the reason it won't start is that it's out of gas, or something like that! rt | ||

When the battery suddenly went dead in my X1 it was so dead it would not even jump start like it had a dead short. I have popped the clutch on mine to start it when it had a good battery. So I conclude that if there is enough voltage to get the fuel pressure up to spec and run the ignition and computer FI will push start. | ||

yep, there's gotta be juice from SOMEWHERE (battery or alternator) -- a complete and utter lack of juice will mean a complete and utter lack of combustion -- me n Thang got our month's worth of aerobic excersize that evening ;-} | ||

I got home with a failing charging system on my M2. I disconnected the headlight and kept the revs up. I got to within a few blocks of home before it really started to sputter. I had driven it for at least 30 miles. Battery had less than 10 volts in it when I got home. Not a major problem, the +14 wire from the VR had come loose. Brad | ||

2000 s3t with the battery too dead to turn over push started several times. Only need enough juice to run fuel pump and ecm. Dave |
