250rtc engine/carb problem

**Chuck Stardust** · 12-26-2011, 06:03 AM

Just a little FYI..... I had a Chevrolet car with a coil in the distributor, and I began having issues JUST LIKE YOU ARE DESCRIBING!!! I used to have to pull over and let the coil cool down, and I changed it and wha-laah! FIXED! You could very well have a coil issue. Check your plug firing and see if its strong when it acts up. Check it when its NOT acting up, and you should be able to tell then. I hope you get it fixed.

well today I went to a scotter mechanic that at first refused to work on the bike but after a little talking he agreed to. After he was done he told me I was having an electrical failure and that I would need a new stator. I asked him to point to where the stator was and he pointed to the cranckcase cover. I havent talked to scooterdepot yet because they were closed but what are your opinions on this? He said the carb was good and that there was no need for a valve adjustment.

If it was my bike, I would try a new coil before I replaced the stator. I not heard of any stator failures on the CG250 on the DF or the Heist but it could be the problem.

You could post a picture of the stator and also the coil, both can be removed easily.

You should ask for a wiring diagram and also a parts book from the manufacturer….do not assume they do not have one, maybe they do?

Then if they tell you they do not have one then ask them if they think that is ok? I would love to hear what their answer would be.

Both of the parts delivered would be nice, testing both a stator and coil is pretty straight forward, but both can also react to heat so you could take a hair dryer to them and see if the resistance changes, when they are hot.

Did you ask the mechanic what the readings were? Did you ask him how many winding it has, number of wires and bolts? That may have been a bit more of a test of legitimacy then where is it…or didn’t you know?

well they have an internet parts book:

yea thats what I am trying to get from them, currently on hold with the manager due to problems with one of their employess telling me a bulb is only a cosmetic thing.
I saw him take apart everything, the stator I have no idea what he did to it but for the coil he showed me that it was out of range, .9 not in range of 2-4 ohms, only thing is replacing it might not prove the to correct the problem as I didnt really see him inspect the other electronics

Where are you getting the 2-4 ohms from as range, the stator reading .9 does not bother me, it seem right were it should be .5 -2 ohms. Above that or below that would mean a bad stator.

Here is good flow chart for trouble shooting, it’s a good reference to have when communicating with a mechanic.

thanks for this, also for the .9 ohms it was a reading for the coil, the stator reading I was not told and didnt have the numbers from scooterdepot.
the 2-4 ohms was for the coil

I would also think that .9 is within the range of resistance on the ignition coil, they have low number typically .5-1.5 ohms.

But if the manufacturer has higher numbers then …well you would like to rely on those values, but the Chinese factor and who is selling the bikes as well all plays into that.

They should be able to send you out both, neither part is expensive.

Then take it back to the mechanic and have him install them and retest.

exactly what I plan to do, unfortunately I am having problems with scooterdepot so I will get back to you guys and let you what happens
