OK I am have problems starting my scooter. I have changed out the R/R and it has a new CDI. The bike will start when hooked up to an alt source of power like a battery charger or jumper cables. When removed from that source it will idle real bad and die eventually. The battery tests are all good from 2 different places. Any help out there.

Hi...are you sure the battery is good....sounds like you need a new battery.....also when was the last time the valves have been adjusted... 257 cc.... .004 intake and .006 exhaust.... the enricher may not be allowing enough fuel when cold.. at idle...just some thoughts...enjoy the ride...

No I think it's a power problem. Like I stated when you pull the alt power source off it dies. And I took the battery to 2 different places and had it tested.

Using an alt power sorce to start the motor is one thing but once started the motor should be able to run without the battery connected......At least all of mine always did. The battery may or may not be good but you may also have another problem in your charging system. When you disconnect the battery cable do you get a big spark? If so I'd look for a short.

No spark. The gauge board does do wacky things when I sceeze the brake. Do you think I may have a short in the cable harness? When it is hooked up to the charger it runs great. When I remove the charger it spit and putters then dies after a few minuets. It ran fine until one day when I was coming home it rained on me. It was a light rain but maybe something happened. The next day it was dead. I check all connections and they dont appear to be corroded. I tried to lay a screw driver across the coil to see if it sparks and nothing. Again as long as I have the charger on it runs fine. Please help if you can as this is my main transportation.

At this point I have no idea what the cause of your problem is except for a bad battery. Do you have a voltage meter? I would check the voltage before attempting to start the motor. Then attempt to start the motor while checking the voltage again. You can check it a 3rd time with the alt power connected and starting the motor. I think you will hind that the battery is dropping extreamly low when you are trying to start the motor without alt power attached.
When you connect an alt power like a charger what size charger are you using and what amperage is it set on?
Once you determine the starting problem you will likely still need to identify why the motor will not run with the battery completely disconnected like it should. The 2 problems are likely connected.
Bob
PS: the reason I asked about spark was when you remove the battery. If you remove one battery cable and there is a small spark this is normal because of the clock and so on. But if the is a fair sized spark it's a good indication of a short. Of course if the battey is near dead there won't be much spsrk because there's not much power available.

im gonna throw money on it being a ground or short in wires especially if it got wet

I'm going to get a new battery today. I will post the results tomorrow.

If he connected the negative lead to the frame rather than the battery terminal, that would temporarily mask a ground problem. |

ah was gonna say that but jlee beat me to it. this is completely tru and has happened to me before on a dirt since they are always getting wet and getting dirt and mud atleast i did on mine those grounds and wires use to short out on me all the time

New battery solved problem. However new problem. I have no head lights. Got turn signals and what I call running lights and brights but no headlights. Also the switch on the right controls that has three settings for lights has never worked.

Glad you at least got it running now. But I still question why the motor will not run (after started) with the battery disconnected. It should run on it's own charging system. So be careful you don't run this new battey dead.
I would pruchase a multi meter and start checking things. Do you have fuses that may have blown? With luck your headlight may just be burned out. A meter could sheck this...... Are you sure the r/h switch is supposed to work? Some scoots have switches that are only intended to meet the requirements of other contries and are not connected when machines is sent to the US. The Roketa 250-54b for example had a switch on the r/h that was not connected for US use. Many of them were actually glued so it wouldn't move.

Your probally right on the switch. I am going to get new bulbs as I'm sure that is the cause of no head light. As for the battery I was told that some bikes require a battery to stay running as the stator just trickle charges the battery. I will put it on the charger once a week to ensure it stays charged. This I never did and the battery was 2008.

This I never did and the battery was 2008. I'm not to sure about the need for a battery to stay running. But I'm not an expert. But even a lawn mower runs on it's own. It's very common for scoots to draw down a battery if the bike isn't ridden a lot. While it's hard for me to believe they say it's the clock and alarm that draws it down while not running. My '08 Roketa had a small problem with this. But my '06 CF Moto V5 hasn't and it still has the org. battery. Maybe it is an alarm problem because the V5 doesn't have one. Be careful with the trickle charger. Some don't turn off 100% and if left on can over time overcharge a battery. Bob |

OK update. It was not the bulb. The switch in the left side was bad. It came loss but works now. Bike is running good but I can tell I need a valve adjustment. Is there any videos out there on how to do this.

The very first sticky post on the "250cc and up" page will walk you through it.

Guys! This is a DC powered CDI system, the scooter will not run with a battery voltage below 10 Volts DC. It also has a 6-pin R/R and the battery has nothing to do with the lights, they run off of the stator which is a 18 coil one with the linhai. The CDI has a black wire that is 12 volts DC and doesn't even have a feed wire from the stator other than the pick up coil. Scooters that run with no battery or a dead battery are AC powered CDI systems because the CDI gets it's voltage from one seperate coil on the stator and if you notice AC systems have a kick stater while DC systems don't. For help on testing the stator click on Manuals; |
