Bike Won't Crank

[TheRev]

Hello

I am having trouble with trying to start my bike. I have spent two years rebuilding everything. I installed the carbs today and have everything ready to start but when I hit the button I get nothing. So I think it must be a electrical issue. So I have a few questions I would like some help with. First off, where does this wire connect to?

[TheRev]

Now when I use a screwdriver to short out the solenoid the starter kicks in like it should. Here is a pic of the two connections I shorted out.



I suppose it doesn't matter since I took the entire bike apart but I did have it running before. Any help would be appreciated. Thanks

Is there a way I can test the handle bar start button? Or is there a way to bypass it? Perhaps my problem is there.

Hey Rev ,I don't have schematic at front of me, but I will try to help you anyway. The starter solenoid gets power straight from battery, low side of the coil is closed by blue wire grounded with starter button on right side control. ..so ,you have to check that you have power, and you do cause you can jump it with screwdriver. ..that usually points to connections in handlebar assembly. Check the plug between , it's close to steering neck...

Great suggestion. I went and checked the handlebar switch and it does have power. With your suggestion I found that the handle bar wasn't grounding the switch because I had powedercoated it. So I took the switch off, and made a jumper from a known ground point and I pressed the starter button at the same time I touched the ground wire to the metal inside the right control and it began cranking. YES!!

So i turned on the gas in an attempt to start the sleepy beast and the gas spilled out of the pod filter. So my guess is that a float is stuck. Is there any way to test that without taking the carb apart? Also, how long should it take for the oil light to turn off when I am cranking the engine? Thanks

Hard to tell from the pic Rev but that looks like the main power wire to the harness. With that disconnected you won't have power to anything.

That wire should connect through the harness to the main power fuse.

How should I make sure the handle bars are grounded? Apparently it is not making ground through the frame because of all the powder coating. Any suggestions.

[BA80]

Grind the powder coating off down to bare metal at all the ground points. We had to do that with RockinD's frame too.

Rev-take a screwdriver and take the handle of the screwdriver and whack the side of the carb that is leaking. That might free the stuck float. Happens quite a bit for some people. Sometimes the float hangs up on the carb gasket.

The earlier carbs seemed to be worse about if you let the carbs bowls get completely empty, it lets the floats/needles drop far enough down that the needles get cocked in the seat. If you have pods, you can shake the heck out of them up and down and see if that helps, but if you have fuel coming out the carb intake, then yes, that's some sort of float/needle/seat problem.

And float needles are cheap on these bikes. They are $30.00 a piece on my ZRX.

I have 79 carbs on mine and every now and then they will flood. Bang on the bowl of the guilty carb and it might stop.

If not we cold send Ivan up there with his dead blow hammer. Hey, it worked on his.

Isn't that green wire the bypass wire to give full power to the coils durning cranking?

If it's the bypass wire then where does it go? It has a female bullet connector on it but I can't figure out where it connects to.

[BA80]

Here should be a wire coming out of the harness to connect it to. I think.

I don't have a bike or a wiring diagram to look at here at work.
