THere might be several variations, but the way I do it is as follows:

1. Turn it on and everything, just as if you were going to start it normally.
2. Put into 1st or preferably 2nd gear. First starts up more easily but is harder on the engine and more jerky when you pop the clutch.
3. If you're at the top of a hill, sit on the bike hold in the clutch and start rolling. Otherwise, stand alongside it hold in the clutch and begin pushing.
4. Once it's up to about jogging speed (which will feel like sprinting if you're pushing it), let out the clutch but be prepared to grab it again. If nothing happens you aren't running fast enough.
5. Give it some gas as the engine sputters and as soon as it kicks in, grab the clutch and slowly front brake your way to a stop if you're running alongside it. If sitting on it, just give gas until it's going, then ride.

I did this with my kz440 for about a month (the starter brushes were worn out), so be careful with the throttle on a 750. Don't want the bike to fly away.

Good luck and get it working again soon!

Ususallly a jump means a hot line off a running car's battery.
so Mag7c went right into push starting....did i miss something?
is it a bad idea to jump off a car? too many amps?

to jump off a car you just put the negative on yer frame and the positive on the red (positive)battery terminal.

Actually I've heard that jumping off a car is a really bad idea for both your bikes battery and the electrical system. Something about it putting out more power then your bike is rated for.

that's why you don't start the car so your not getting the extra power

There should be absolutely no problems jumping off a car, running or not, so long as the bike and car both have a 12v system. The bike will only draw as much current as it needs, regardless of what the car's alternator/battery is capable of putting out. Now if your bike uses a 6v system (or the other vehicle is on a 24v system, such as a bus), then don't bother trying to jump start unless you like smoke and sparks.

ive jumpd plenty of bikes, ive always herd mixxed opinions on doing it though. ive had people tell me to use smaller gauge wire with gator clips so it cant pass enough current, no idea if thats a good idea or not.

also did the bike sit for 6 weeks with gas in the tank? if so you might have more problems than the batt.

DO NOT jump start your bike off a car. Unless you want to spend hundreds of dollars to replace components of your electrical system, such as your voltage regulator.

I may or may not know this from personal experience.

I'll never tell.
