Also check your voltage onthe battery - the last time I had that happen, I thought I'd blown another regulator, but the battery had just given up the ghost. Pulled over for a funeral procession after a long ride, and then - nothing. So, check your voltage, check your connections (as others have pointed out), and then check your regulator.
Someday, I would love it if someone could tell me how to push-start a bike....
As far as push-starting a bike..
First thing you should do is find some open area so you have enough space to begin the actual pushing. This process is much easier if you have another person doing the pushing or if you find an incline so that you can push yourself while on your bike.
Turn your key to the “On” position and have your bike’s engine stop switch (the one that kills your engine) in the “On” position as well.
Shift your bike to 2nd gear. This way when the bike comes to life, you don’t get jolted out on first gear.
Grab and hold down the clutch lever and proceed to have your bike either pushed by someone else or by yourself down an incline. By the time you hit about 5-10 mph, slowly ease off of the clutch. As soon as you hear or feel the engine come to life, twist the throttle so you let in more gas to get the engine going. Make sure when the engine starts up and you twist the throttle that you hold down the clutch immediately
. Otherwise serious injuries may occur if you forget to hold the clutch down and you turn your wrist too much on the throttle. That’s it!
I recommend doing this when you really don’t need to. It’s a good thing to practice and learn before you really need it.
