Have a guy working on getting motor running, but...

The factory wiring does include a clutch sensor - you should see it on the wiring diagram above. It's labeled as "Starter Disconnect Switch", green/yellow wires. If you just connect the two wires together, it thinks the clutch is always pulled in, and will always start.

A PO put an aftermarket clutch handle on my bike that didn't include a sensor, so I have the connections plugged together in my headlight bucket for this.

You say that there is no ignition switch, right? Just "hotwired" to the start button? You still need something that will switch power to the coils and ignitor. The start button just closes the starter solenoid. My guess is you don't have power to where it should be.


Sorry to make it more complicated, but after you get spark here's some other things to look at. If the guy you bought it from didn't know enough about electrical to figure it out, I'd suspect everything else as well.

-There's pod filters on the carbs. Do you know if the carbs have been properly re-jetted for them?
-You may have to go one heat range down in the spark plugs as well. I don't expect that you'll have real great air flow to cool your engine, nor will you be doing the kind of speeds a bike normally would.
-Read up on information on here about carb tuning and doing plug chops. It's pretty important to know if you're running rich or lean, unless you want to learn how to rebuild an engine as well.

These are all things to think about later. Most importantly, get spark first.

Thank you Fender Freak for that tidbit of info, I will be sure to do that. And thank you as well Rudy, once I get it running I will be sure that I evaluate the airflow and carb situation.

Do you know how I would go about doing that?

[fenderfreek]

Check the circuit where the "engine stop switch" would be. It's the kill switch on bikes, on yours I believe it's orange/white and orange wire. It may have just been permanently wired together if the PO didn't want a kill switch.

[Zhamm717]

Okay thank you, another thing I will have to do. Any more from anyone? hahaha

[rudy]

Do you know how I would go about doing that?

Here's the circuit highlighted. This is all you really need for it to turn over and fire. You may also want to check the other wires that go from the ignitor to the pickup coil, and the white and yellow/blue ones going to the coils. They're pretty easy to follow on the schematic though.

Red = Ignition circuit up to ignitor
Green = Starter circuit

Excuse the sloppiness. Just using MS Paint at work.

That is fantastic Rudy, thank you so incredibly much. You guys around here are geniuses!

No worries. It's kinda my day job. Electrical engineering, not being a genius..... though, maybe that too.

My brother had something similar to that in the 70's but it had a BSA 441 Victor engine. It overheated and seized in Baja. Be careful about heat.

Yes, I have been reluctant to say that the motor is on a go-kart but you have to admit it's a pretty cool idea.

I bought it of ebay from a guy in maryland. And I love in Grantville, PA. Near Harrisburg/Hershey/Lebanon, if anyone has heard of the Hollywood Casino, about a mile away from there.

Could be an idea to get an electric cooling fan from an old wrecked car and hook that up in front of the engine. Just an idea. I know that's what I would do. Though it may draw a fair bit of current. Don't know if it would be too much for the charging system or not.

[Zhamm717]

Yea I do anticipate some other problems down the road, get getting to those problems will mean I have solved others, so I am excited to see what happens.

[posplayr]

I should mention that someone just recently posted a schematic for a completely rewired harness. It is partitioned into various elements of the electrical subsystem and so even though I would have done a few things different, it is a scaled back harness that captures most of what your go cart would need. There was a link to a pdf; I have that but not the link provided by the author. He was from Sweden I believe.


Maybe he will see this and pipe in.

[Zhamm717]

Hey thanks for the post. To answer to what you asked, No, its not an Odysey, However I would love to have one. It is a custom built street cart, but possibly will be eventually upgraded to a full suspension set up. About overheating, if that happens I could easily make a scoop over and around the APC race seat to re-route the air towards the engine.

[Zhamm717]

Awe man, those Odysseys are so cool, I dont know why there not around anymore (atleast I think there not). They look like they would be so fun, especially when they are rigged with suspension.
