The starter motor turns when it isn't mounted and the start button is pressed. Doesn't that indicate that the solenoid is working? yes, this indicates the solenoid is working. |

I just checked and right now the battery is producing 12.45 volts and the starter has 12.25 volts when the start button is pressed. If there is only a 0.20 volt drop across the wiring through the solenoid and to the battery doesn't that indicate that the connections are good? this small resistance doesn't sound like much, but when you start dumping a lot of amps through it, it will cause a voltage drop that would be enough to keep the starter from turning under load. this is one of the reasons you should purchase the entire cable for your car starter. those aftermarket end clamps will soon get to where they will fail, because of corrosion. how can they not have good connection when the cable is literally clamped in there. but it will, you can count on it so, check your battery circuit connections VISUALLY. remove each one, and remove all the stuff that doesn't belong there, off of the wire AND the screw terminal. you will have 2 for the battery, 2 for the solenoid, and 2 for the starter. also, make sure the start ground is actually mounted to the starter mounting ears and that the metal has been exposed. avoid engine ground points. aluminum soon develops an oxide that is resistant to electricity |

Very good advice Twenty, but I think he's turned a corner with this one.... Aren't Chinese scooters FUN?...LOL!

Very good advice Twenty, but I think he's turned a corner with this one.... Aren't Chinese scooters FUN?...LOL! actually my 50cc was fun to own. gave $300 for it, rode the crap out of it for a couple of years. changed the oil a few times, then sold it for $300 bucks when i got my 250. i remember waking up in the middle of the night, and the first thing that came to my mind was riding my 50cc. and off i would go. hardly no problems at all with that bike. the plastics was quality material, electrics likewise this is the reason i can't say all chinese scooters are junk. because that simply isn't true. |

Oh I agree with you on that point, but it does seem as if the 250's have more problems than the 125/150 class of scoots. (You think if anything they would want to put more QC into them,)

I added a grounding strap between the frame and the starter motor. Now it turns over good and for a long time. However it wouldn't fire. I pulled the plug wire put an old plug in while touching the frame and turned it over and I don't see any spark.
Any ideas how to get spark? What could I have ruined putting the battery in backwards? I am pretty sure he key stayed off during it.

I added a grounding strap between the frame and the starter motor. Now it turns over good and for a long time. hmmm . . . the starter ground needs to run from the starter to the battery using the shortest length possible (disregarding routing issues). i have no idea how that little green wire ground is handling all that starter current. how many ground wires do you have connected to the negative battery terminal, and what color, size are they? my experience is with the 244, so someone else needs to provide input in this area. i want to make a point here though. my bike has an auto choke connected to the carb, and is run from the stator. it also appears that this auto choke is made for 12vdc, and is interchangeable with the stator model. so, if you get a 12v autochoke, make sure that it operates from 12v, NOT the stator, and vice versa. it took me awhile, but i finally figured out how to get rid of this little critter too. it can't be just removed, it has to remain in place, but rendered non functional in the "no choke" position. it can't be just unplugged, the device itself must be modified. be advised though, i still had to manually choke the engine to get it started sometimes. the design of my airbox allowed me to do that. start the bike with my right hand, while reaching down and blocking the airbox intake with my left. yes, i bypassed both brakes with my rewiring job (not recommended) BTW, sparks can be pretty hard to see in daylight. also, i recommend an iridium spark plug. they aren't cheap, i paid either 8 or 12 bucks for mine, but definitely worth it. |

Spark is back. I had unplugged a couple of connections to get to the starter.
