I heard that your rectifier and stator will get hot if you don't use the AC power it generates for the lighting. What you don't use gets shunted to ground, which will get transferred to heat, right?
I did that for a while, and it literally made the unused lighting wires go up in smoke. And, running 55w off of that tiny battery ran it down in about an hour. Just not a lot of wiggle room with those little batteries.

Somebody disconnected the ignition to attempt to steal it. Amateur hot-wire job. Or, maybe they lost the key, and tried to be cute.  |

Just a thought....
Are you using 2 different weight rollers in your variator? Do you have them staggered correctly? That could cause your variator to go off balance. Have you weighed your rollers to make sure the factory didn't send one that is lighter than the rest?
I'm just tossing out ideas. Good luck.

It does start when I jump the solenoid. I think you are right, and it is the solenoid. It doesn't click, though. Don't they normally click when they have gone bad? I am putting a 50mm BBK on there tomorrow. I started taking it apart today. I put a tester on the starter switch, and it is fine. I may have another solenoid sitting around. I'll replace it, and see. If it's not that, I probably fried a ground somewhere. Electrical issues are the worst.  I ordered an 11 pole stator. I need another hot wire for lights. I'm going to put that on when it comes in next week, and put one rectifier on for the bike, and run the other wire from the stator to another rectifier for the lights. Or, I may just hook up a 7-wire rectifier. I heard that you need to use most of the juice that your stator produces, or things start getting hot. |

I figured it out. I also figured out that I'm an idiot.  I'm actually an idiot X2. First of all, always check your fuse when you are not getting a spark.  I'm an idiot X1. Secondly, I connected a ground from the scooter to the third hot input on the 7 wire rectifier.  I don't really know how it worked fine for 2 weeks, and just screwed up when I hit the flash button, though. I'm an idiot X2. If anybody needs some advice on how they might have screwed up their scooter, I'm the one to ask. I'll see myself out. Something that is still puzzling me: I checked the starter switch with a multimeter. It is fine. The starter still won't engage with the button. Is there a relay between the switch and the solenoid? Or, is the solenoid and relay all one unit? Electricity has to go somewhere, and it is weird what fries when you wire something backwards. It obviously arced off in the solenoid/relay, and fried it. |

Definitely sounds like you have air leaking somewhere. The air/fuel screw is probably not going to fix your issue. Start by checking the hoses coming off of the nipples of your intake manifold. You can spray them with carb cleaner, or WD 40, and if it bogs, you know where the leak is. They could have knocked one of the hoses off putting your head on, and forgot about it.
Question: Does it sound any different? Louder?

I posted this same thing on the general board. Sorry mods, I'm new. You can delete that one.
Hi, guys. I'm new. Look forward to trading ideas. I have a 50cc Jonway. Got tired of paying for gas and insurance. It is now my sole mode of transportation.
Kind of complicated, as electrical issues are.: I put a new stator on a couple of weeks ago. A screw had gotten in the flywheel, and chewed the stator up. I don't feel that is related, but that is that.
Here is the deal: I put a car bulb in my scooter, and it melted the lense. So I put a couple 55w fog lights on the front. The AC voltage was blowing bulbs, so I used a scooter rectifier to convert the light wires to DC. It was a 7 wire rectifier, so I hooked the blue high beam, and the brown light wire to 2 of the yellow AC inputs on the rectifier. I left the white, low beam wire alone, and just capped it.I connected 1 light to the white output, it read 12v DC. I connected the other light to the red output, it read 9v DC. I connected both of the light's black wires to the green ground wire out of the rectifier.
I was riding the other morning, and accidentally pressed down on the high/low beam switch. That flashes both the high and low beams at the same time. My lights cut off for the second that it was pressed, but then came back on. I pressed it again, then the same thing happened. I hit it again, and the lights stayed on. This puzzled me, but from then on, nothing happened when I hit the flash button.
BUT, the next time I tried to start it, the start button did not work. I jumped the solenoid, and it would start. So it was something before the solenoid.
Then, this morning it would not start at all. There is no spark from the plug. I unhooked the kill switch/start switch from the handlebar, and it doesn't appear to be fried.How can I start testing? Is there any way I can rig it to get it running until I have some time on Saturday to mess with it? This 50cc Jonway is my sole means of transportation.
I just thought of something. This rectifier is only being used for the lights. I am using it to convert the AC light wires to DC. It is bolted to the frame. Are they grounded by this bolt, or are you supposed to ground them via the green wire? Did I screw up by using the green wire to ground my lights?

I just thought of something.
The rectifier I'm using for the lights is a separate rectifier, and is not being used for anything else. I used it just to convert the AC light wires to DC.
It is bolted to the frame. Are they grounded by bolting them to the frame, or is that green wire supposed to be connected to the frame for ground? Did I fry it by using the green wire as a ground for my lights? Could it be screwing the ignition ground up now?

Thanks! I do appreciate the response. I look forward to getting to know ya'll. If you have a scooter, you either have a good mechanic close by, whom you are on a first name basis with, or you have become a backyard warrior. I fit in the backyard warrior group. I have invented new swear words trying to figure out some of the problems with these things. Owning a scooter is a lifestyle, and I end up planning some sort of project every Saturday. I have also learned that being a car mechanic, and a scooter mechanic are two vastly different things. I am pretty excited about installing the BBK. I have decided to ditch that air box. I think I'm going to put on one of those cone filters that fit right on the carb. I am going to order a few different size jets. I figure that I won't go over a 105. Does that sound right? If I get a  ,  , 100, and 105, one of those will do, right? |

Hey, guys and gals. Just joined. Been reading the board for info for a while, and some interesting stuff on here. I have a 50cc Jonway. I love it. Anyways, just ordered a BBK, and was wondering if I really needed to upgrade to the performance exhaust? It's pretty expensive(for me). I don't really need to go much faster than it does, just want to be able to pull hills without causing a traffic jam. I have installed about every other upgrade possible. Have it running well on a  main jet. Starts easy, power is about maxed as it stands. I imagine I will probably go to at least a jet with a 50mm hole in there now. I don't want to throw it out of wack, but would like to avoid the new exhaust, if at all possible. At least for a week or 2, anyways. Thanks, ya'll, and glad to be here! |
