Bicycle Motor Spark Problem?

How can I hook three wires together two males one females? The kill switch ground is a loop where do I connect that?

I removed all my ends and just hooked them with a wire nut.

Heres how it works.

Kill switch is an open. In other words dead wire till you push the button. It is not in anyway effecting the operation of your engine. However when you push the button, it grounds the circuit before the power goes to the cdi. Which kills the engine.

One side of the loop goes to the hot wire from the engine and one side is ground from the engine (black)

On my engine anything I wire to the white wire kills the engine so I don't even use it for lights. it just hangs there. Matter of fact, I need to tape it off. One of these days its going to do a ground on me at the worst moment.

Ps. on my bike the connectors came apart I didn't lose anything by cutting them off.

Okay thanks for elaborating. I think I understand, I just really don't have any knowledge of electricals. We'll see how it goes this afternoon once I get home. I'll let you all know. Thanks everyone for addressing my problem, this forum is very helpful!

Do let us know what happens it helps us all when a problem is either solved or a perceived solution doesn't work. Don't give up no matter what we will keep trying.

ya don't give up. the rush when the bicycle engine finnally fires up is worth the little set backs.

Didn't get a chance to take a look at it this afternoon, hopefully tomorrow. Deacon, what part of NC are you in? I'm out of Chapel Hill.

High Point,

As for your problem, with these bikes its trial and error every time you start it. that the fun part. So if this don't work we have lots of other things to try.

Well I had a chance to run the bike yesterday. Well I hooked the black to black and the blue to blue from the coil to the motor and unhooked the killswitch coming off of the throttle completely. The bike runs poor for about 1-2 miles then once I hold it WOT it will accelerate run fine. I have the old GruBee kit (2006) with the PREMIUM CARB which I haven't seen anyone run. It doesn't fit on my manifold with out using electrical tape as a shim. I'm thinking that the carb is too big and is only good for WOT runs. This is not good because I haven't run but a sip of gas through it and have had several WOT runs. Ah ****, I'm fed up. I did buy the Happy Time Carb and Big Intake Manifold off ebay this morning. We'll see if that fixes this. Any inputs guys?

if you have any air leaks around the carburetor and the manifold it will run poorly and that's what it sounds like to me but i am no expert and still learning. a way to check this is if you can get it to idles spray a little starter fluid on the connections where the carburetor connects to the manifold and if it changes you have a vacuum leak. i know it is discouraging but is worth the time and effort you put into it. we all had problems getting our bikes to run properly and it was frustrating as heck. when all the little bugs are out of it you will look back and laugh at what it took to get things right and smile big time as you ride
