Metal shavings in crankcase of Baja Storm 125

[Frank Angerano]

In order for me to properly see or say what’s going  on is to find the diagram for that bike. After I have that it should be a breeze.  

[Adrian Ciotinga]

To get to the starter clutch I had to remove the stator. When reassembling the flywheel and stator I might’ve installed it backwards but I don’t think so after looking at it some more.

Anyways since the motor is a gy6 motor would a general gy6 wiring diagram work?

[Frank Angerano]

It should work or be close enough to see what’s what.

That’s a great image @mikeexplorer   

I only see two yellow wires in his picture.  So I’m wondering if it’s a single phase stator. 

There is three wires, a bit hard to see since its yellow and I enlarged the image.

 

[Frank Angerano]

I see that in your picture. The stator on the bike in question has two yellow wires.  It looks like a single  phase stator which would only have two wires.  

 

[Adrian Ciotinga]

Sorry for not posting updates in a while. The stator works! I ordered a new one and figured out how to wire it in and now it sparks strong! I have spark and compression but no fuel. I am going to remove the carb and fuel petcock to clean them both as I see no fuel in the fuel line. One question: How do I remove this throttle thing on the carburetor so I can take off the carb completely?

[Frank Angerano]

Nice work ! That throttle cable will come off by grabbing that throttle control on the carb and turning it and pull the cable off as it slacks. Almost like you would a bike chain.   Then once the cable is off of the main part line it up with that slot and slide it out.  

There should be a part that holds the throttle cable into the carburetor also. You can unscrew that as well to slack the cable.   

[Adrian Ciotinga]

Removed the carburetor completely from the quad bar the connection to the throttle (I still need help with that). Anyways what is the best way to clean a carburetor?

I just saw your post on how to remove the carb after I wrote my previous post. Thanks for the help!

[Adrian Ciotinga]

The carburetor plunger is not moving up and down with the throttle. Is this an issue?

Here’s a photo:

Nope not a problem.  The slide works on a vacuum.

So have a clean preferably white towel or an old pillow case.  I like to see what’s comes out and it’s easier to keep all the parts local.

Take it apart and keep all the screws for each part separate on the area you working on.  If you have a can of the air people use to clean off computer keyboards it helps. 

Something  to clean the small holes out. If you need something I always recommend taking a strand of a piece of bicycle brake cable , it works great.

This will give you a better understanding of how a cv carburetor works. 

[Adrian Ciotinga]

In the process of removing the carburetor I think I might have disconnected a wire or two. After fully reassembling the quad and hooking it up for a jump I pressed the starter button and nothing happened. I gave it a closer look and saw that a wire coming from the assembly got unplugged and when I plugged it in the starter motor spun. However I still cannot get the quad to start and the front right headlight is not working either. I have no spark.

[Frank Angerano]

 

As far as the headlight goes that may be localized to just the front light.  Is the left side headlight working ? 

As far as spark goes you have to go back and look. Chances are you missed something.   Also have you checked that all the wires are connected to the battery correctly and nothing was left unconnected?

kill switch all good ?

Ground wires connected? 

 

[Adrian Ciotinga]

The left side headlight is indeed working. Is it possible that I don’t have spark when turning the motor over by hand but do when jumping it? Every other time I tested for spark I did so by turning the motor over with the starter.

[Frank Angerano]

It is a single phase stator so it would need a good pull to generate spark.  Try it with a battery and see what happens.   

[Adrian Ciotinga]

It sparks but doesn’t start. I am pretty sure it’s getting fuel but how would I check that?

Fuel is running through the petcock for sure.

[Adrian Ciotinga]

It’s about 110 outside if that makes a difference.

[Frank Angerano]

Only for sweating your as* off it makes a difference. 

If you have any starter fluid spray it into the air intake as you are trying to crank it. 

If it fires then the engine is obviously starved for fuel.  If you don’t have starting fluid put a drop of gas in the head where the spark plug goes and and put the spark plug back in and try to fire.  

If all that works then you failed someplace on the carburetor cleaning. Maybe a stuck float or the fuel port coming from the needle is clogged.  It happens.  

[Adrian Ciotinga]

I tried what you suggested and the quad started right up no problem! It ran for a very short time. I assume my next step is to fully disassemble the carburetor and clean it?

[Frank Angerano]

Yes 100% take a can of carb cleaner and spray all tye ports out.   I have a feeling the float is stuck closed.  

Also the main and pilot jets should be taken out and sprayed.  

[Adrian Ciotinga]

I cleaned the carb and the quad ran on starting fluid, however in the process of cleaning the carb I could not get carb cleaner through the place where gas enters the carb from the tank. I fear this might be my problem. How can I unclog this?

This is the connection I am talking about. And BTW the fuel line does not have gas in it when attached to carb but petcock is not clogged

I tried to start the quad without a gas cap and it didn’t help.

[Frank Angerano]

So most likely the vent on the carb is still clogged.   Try to Blow into the vent hose on the gas cap. This may clear the vent line  in the carb.  Make sure your gas petcock is in the right position and and blow into the hose on the gas cap.  Try your reserve as well.  That petcock may not be working right.  

[davefrombc]

Did you remove the  carb from the motor and disassemble  it to  clean  all the  jets and passages?   If the inlet  port is  clogged or the needle valve in the  carb is stuck  closed  you would not be able to  blow through that  line into the  carb.

[Adrian Ciotinga]

I have to remove the float to clean the needle valve correct? I just sprayed under the float but apparently that might not have been good enough.

 

[Frank Angerano]

You have to take the carb apart!  Cleaning a carburetor means taking the carburetor off of the bike and dissembling the carburetor.   You can’t just spray a cleaner into the carb or under a needle valve etc and hope it works.  Take it off clean it properly and make sure ALL paths are clean.   Then reinstall and you will be fine.  

[Adrian Ciotinga]

I took the float bowl and the top of the carb off. What else should I take off? I've never done anything like this before.

 

[Frank Angerano]

The carb needs to come off of the engine.  Take it completely apart and blow out all orafaces with tye carburetor cleanser and even a small piece of wire to stick in the holes.   You should be able to blow into that fuel line and it should come out of the bottom of the float area where the needle is.  

 

[davefrombc]

The blockage could be  in the port  where the fuel  line is connected . That  leads to the needle  valve on the float. If this is your first time doing a total  disassembly  and clean,  watch the video  Frank  posted , then   work on your  carb .. Take  your time and  check  all  passages  and  jets  for  crud  blocking them.  Keep track  of what  goes  where  as you remove the pieces  and reassemble  the pieces.

[Adrian Ciotinga]

It lives! And seems quite powerful for only 8.8 horsepower. Granted this is my first ATV but whatever. Thank you guys for all the help, especially Frank Angerano for assisting me throughout the repair.
