Basically, the starter is grounded through itself so there is only 1 big red + wire connected to it. That wire runs to the starter relay. The relay has another big red wire that runs straight to the + side of the battery. The relay is triggered when you squeeze the brake lever and press the start button. Once triggered, the full voltage of the battery is passed through the relay to the starter. The relay has a two prong connector that is for the triggering circuit. The reason for the relay is because the start button would melt if you tried to run the full battery current through it so the relay is just a heavy duty switch. Some guys call them solenoids. Now to test the starter, cross the two main poles on the starter relay with a screwdriver. This by-passes the relay and the starter should turn as long as you are touching the screwdriver across the poles. The engine must be grounded to the battery. The auto enricher has a two pronged connector as well so it's easy to plug the relay into the wrong connector. Question: Do you own a test lamp? If so, test for 12VDC at the scooter side of the connector with the key on, brake lever squeezed and the start button pushed . One prong is ground and the other a hot so if you get 12V on 1 prong then that's good news. The star button is working correctly.

No test lamp just a multimeter

so i checked it with a multimeter--i get the same reading that I do at the battery. pressing the starter does absolutely nothing...no noise no nothing.

Okay so what you need to verify is whether or not the start button is sending voltage to the relay. You check for 12VDC on the scooter side of the plug connection that goes to the relay. Were you able to make the starter turn by jumping the relay? A test lamp makes it really easy. You connect the wire clip to the frame (ground) and then touch the pins/prongs with the sharp end and the light lights up when there is power. Simple and fast.

If the starter turns when crossing the relay, and the relay is getting voltage from the button but the starter doesn't turn when you press the button then the relay is bad.

ill have to grab one of those. Jumping the relay? Using the screwdriver? Also, I checked the mess to see if that and the auto check were mixed up, the solenoid does not clip in however, it looks like it is wired in at two connections rather than having the plastic clip.... she's a mess... but I can not admit defeat yet!

Yes cross the relay poles with something metal. The starter should turn when jump the relay.
Somebody wanna back me up on this. Cripley apparently thinks I'm crazy.

haha no Fox, I think you are a genius I know jack about these things! I will try and grab a lamp tonight so i can test it out.

I think i figured out where my air noise is coming from?! What he hell is this? This is on the bottom of the cylinder head valve.

Awww shit! lol i thought that might be what it was.... sad that once I got inside I had to think..."did that have a muffler"? damn Fox...I may have to admit defeat...
BUT--- it should still run without an exhaust right? I have one of those brains that needs to know why something does or does not work... it's a paint in the ass

Yup, it needs an exhaust or you run the chance of burning your valves.

When burning, plastic and rubber emits toxic fumes. I would avoid roasting marshmallows over that fire.

so what is the physical size difference between a 50 and a 150cc?
