Fix and Maintenance on 250cc Roketa By abdulmuhsee (Read 4,953 times)

I looked up seafoam online and it has a powerful effect on water in gas, it binds to it and gets it through your system. So, I'm wondering, are you getting your gas from the same source everytime? Possibly it's contaminated fuel. Second, it helps the plug fire, so pull the plug and send us a picture the electrode and tell us where you're getting your gas. Rich

abdulmuhsee,
OK, now with what you told us that adding seafoam made the problem go away.
SEAFOAM: Is a cleaner and stabilizer if you have water in the gas. Seafoam cleans your gas lines and the little gas passages in your carb.

1. So with that information, you already know what is causing the problem.
a. Your Carb is getting Clogged with little bits of crud.
b. Your Gas Filter is getting Clogged.
c. Your Gas Tanks has Crud and is getting pumped out and causing the Clogged Carb and or Filter.

2. So the First Thing I would do is:
a. Start from the Source, Clean out your Gas Tank.
b. Take the Gas Line from the Tank to the Pump off and make sure its Clean.
c. Install a New Filter.
d. Take the Gas Line from the Filter to the Carb and make sure its Clean.
e. Take the Carb Bowl Off and clean the Carb.

I think the Crud is coming from your tank and is causing the clogging of fuel. Other than the Tank the only other place of crud would be in Your Carb Bowl.

I'll tend to agree with kczukiman on this one... sounds like a bad coil to me.

I get my gas at different places every time, but it has happened after filling up at more than one gas station. As for everything else you said, I have no idea what it was. Even I just wrote it off as bad gas the first couple times it happened and hoped for the best

Take the gas line from the tank to the pump and make sure it is clean

Where is it? How do I make sure it is clean?

Install a new filter

What filter; where? How do I remove it and install a new one?

Take the carb bowl off and clean the carb

Again, that's a completely foreign language to me. I'm sorry if I'm an idiot, but I know nothing about cars or motorcycles.

I don't want to start an argument but with the limited mechanical knowledge that abdulmuhsee appears to have he may cause more problems that he cures. That is the only problem with these inexpensive Scooters no one has a good repair manual, one with good pictures and illustrations as to what things are and where they're located. But once you figure out the basic layout they are easy to work on. I've done things to both scooters that I've owned that I would never have tried on the motorcycles that I've owned, and I actually enjoy doing it.

Well I do not agree with the coil having a problem, remember he said he added Seafoam and everything was peachy keen for 4 days. Seafoam does not cure coil problems or any other electrical part. I believe he either has crud in there someplace, really bad gas or his float is sticking and laying it down shifts the crud blockish, water blockish and or frees the Float.

Coincidence... I say coil based on the symptoms.

EXACTLY; without a picture showing exactly where the part is and an explanation of what I need to do, the only thing I'll accomplish is taking the bike further apart with no guarantee that it goes back together.

Is the "coil" an easy fix that someone like me can do? I'm more than willing to try anything within my abilities and I'm getting short on time to fix this without having to attempt walking to where I need to go.

Okay, so like I said, I believe this might be a coil issue and the Sea Foam *fix* is unrelated and coincidental.

This is the coil:



It is basically your spark controller for the engine. It is the spark plug cap, wire and controller and is easy to find.

If you want to try and clean your carb like Alley says, here's a link to my carb cleaning video. It is very easy to do, even for a beginner.

If you are getting particles in your carb it might be due to deteriorating fuel lines. If your scooter still has the original lines on it, they are known to deteriorate from the inside out, or in other words, you can't see if they're bad.

Changing fuel lines is covered in my PDI.

Even I'm starting to think it's electrical now, and the seafoam may have been a coincidence. I drove my brother home and back on the scooter with no problems; no conditions changed since it happened last other than it sitting in the garage without its shell for a few days.

Even though it SOUNDS like a fuel problem, it's very possible that something electronic that's supposed to be sending a signal somewhere is intermittently cutting out because it's hot/something and not telling the bike to do something it should. I'm not even sure why it has to have such a myriad of electrical wires everywhere bunched in rubber and electrical tape, because heat = electricity's enemy, and it seems like the antithesis of mechanical engine function.

There's no way I can possibly know which part is the culprit without replacing every single part in question, which I cannot do, probably not even one part, so every time I ride it, I'll just be taking a huge risk. My gut feeling at this point is that the electronic fuel pump is getting hot and not pumping effectively when said problem happens, and I'd really like to re-install the vacuum pumps if I was able to do it; I don't trust electrical things to pump gas into my scooter.

The only thing I was able to do was change where the ground wire was positioned so the thin metal disc under the screw is now behind the computer thing instead of in front of it, though I doubt that was the problem.

Any update?
