Hey new guy here!

[Nradner]

Hey guys!

My names Nick. I have been building China girls for years, then I had a few kids. I was on this Netflix show, outlast season 1 a few years back and had a few extra dollars and I wanted to build a totally badass bike for my son. Anyhow, I’ve built a felt faker with a phantom 85, and I’m having a hell of a time getting it to run.

I know this bad boy is supposed to use all stock parts until break in; but I can’t even get her to start

I’ve had issues getting fuel into the cylinder, as well as a maybe weak spark condition. I ran the #s on the magneto coil, and I’m getting readings all over. Replaced the magneto with a 12v stythus, and the stock CDI with a spare BBI stage 1 (JUST to get it to start; not to keep on there once she is going.

I have compression, but I don’t smell fuel on the plug. I drained the tank, took off the in line fuel filter just to get a flow. Still nothing.

I know this is very vague right now; but I have run every test for fuel spark and air to get it running I can think of.

Sometimes it “pops” but it will not catch and idle. Stock adjustments have been kept on the Bofeng carb. I’ve taken the carb apart more times than I like to admit.

Checked and rechecked the wiring off the CDI. Grounds are totally clean.

I’ve grounded the plug on the cylinder head and can see what looks like a very weak spark. But even that should ignite ? Shouldn’t it?

Note: when the magneto cover was removed upon inspection, the spinning magnet was making contact with the coil. I’m wondering if that depolarized the magnet?

There are no leaks coming from the base gasket or exhaust. It just doesn’t seem like fuel is getting into the cylinder. I have searched every issue and lurked in this place for weeks before finally deciding to say something to yall

Anyway. Not expecting anyone to fix this entire thing, but any threads that I might have missed concerning a phantom 85 no-start I might have missed would be cool. I’m GOING to get this thing running. I just might have to totally rebuild her from the ground up.

Thanks!

If you're running the factory plug, ditch it for an NGK BPMR7A. Did you already gap the coil properly? If not take a business card, loosen up the coil, and put the card between each side of the coil and magnet and tighten ot to the thickness of the business card.

I'm sure you must have done the obvious disconnect of the kill button an then try to start it just in case it was grounding out at all times.

 

[Sidewinder Jerry]

Have you tried starter fluid in the carb yet to see if it'll crank?

You have a cooked cdi or magneto sounds like if it pops. Already damaged the magnet so buy a new ignition completely. There are easy tests on YT for ignition components but seeing ya damaged them already I'd say just swap em. If you think your not getting fuel look at the carb dummy lol if you've built as many as you claim then you should know all of this.

 

[Mike Cyanide]

Btw idk if I'd put heat wrap on a phantom exhaust especially during break in. That seems like fast track to Kentucky fried phantom.

 

[Gordy]

Kentucky fried phantom.

I think I've got an idea on what to call my bike.....

Ready my mind as I typed it bud!

Appreciate. And yes magneto is dead nuts straight. Trust me I’ve torn that carb down and swapped for a known working one Parts have been swapped. Getting a stronger spark now, so I’m gonna mess with it a bit more

Might be right. I’ve had good luck with it in the past, but first time messing with the phantom, so I’ll take any advice that sounds good!
