Help with 2006 zongshen storm 250cc gs

[craig1979]

Bought a zongshen storm.. Put a battery in and away I rode

After 3 days was riding and the bike shut off.. Started again then got it home.. Replaced the spark plug, coil and lead then it rode fine for a few more days then did it again.. Bike started again after a hour so o rode it home, waited a day to try it and it started first go

Anyone have a idea what is wrong

[Weldangrind]

CDI would be my guess. They're cheap, so buy a couple.

[craig1979]

Living in Australia it's a bit harder to get hold of a cdi

Is the cdi known for working then not working

[katoranger]

It does sound a CDI failure. Yes they are known to fail also.

[craig1979]

will try and get my hands on a new one

if its not the cdi where should i look next

[humanbeing]

AC or DC CDi?

not sure lol

the "Programmable" ?
http://item.taobao.com/item.htm?id=9465817427 | The success story : http://www.motorfans.com.cn/bbs/t_16895002.htm

Humanbeing, is that CDI specific to the Yamaha / Zong 200? Is there a version for the CG200? Also the OHC Honda 200 clone? I tried to read the success story, but Google translate is not good enough.

[humanbeing]

This http://item.taobao.com/item.htm?id=3289740994 had English version. 1/3 of their customer is outside PRC. Simple written English is quite OK for that developer.

That developer's warning: some new model's pinout isn't as the "generic", you MUST know which wire = which function, otherwise ... http://www.motoyes.net/bbs/thread-534491-1-1.html

going by the picture of the plug you put up and using a test light while trying to start i get the following

1 - black/yellow - nothing
2 - green - nothing
3 - green - nothing
4 - blue/yellow - flashes
5 - empty
6 - white/black
7 - black/red - constant
8 - empty

I also suspect the CDI unit is failing. All of the Chinese CDI units are poorly manufactured. :roll: The CDI units usually exhibit intermittent failure for a few weeks before they die completely. ;) I suggest you order several spare CDI units from Taobao.

even translating that site to english is was tuff to read lol.. need to work out the price difference

[Weldangrind]

The folks at www.tbtrends.com can help you with that. Just paste the link of the Taobao item you want into a tbtrends order form, and they'll take care of you.

[craig1979]

cheers will check them out

[craig1979]

Just ordered one.. will let you guys know if that was the problem

cheers to all that helped

You're welcome. :) Even if the CDI unit is not causing your current problem, you are wise to have a spare. Among other things, a spare CDI unit greatly facilitates troubleshooting the electrical system. Also, it's only a matter of time before the original CDI unit fails. I am currently using the fifth CDI unit on my Zongshen 200GY-2. The harsh vibration from off road riding accelerates the death of the Chinese CDI units, so I average about 12,000 miles of riding before I need to replace one. ;)

i hope it is the cdi unit cause im running out of patience with this bike real fast lol

The Chinese motorcycles certainly have far less support than Japanese bikes. ;) If the CDI unit is not the problem, we can certainly help you diagnose the source of your trouble. The problem might not even be electrical. However, it's always good to have at least one, spare, Chinese, CDI unit. ;)

Did you order an AC, or DC, CDI unit? Do you have a wiring diagram for you bike?

Spud :)

[craig1979]

i have no idea which one i bought.. just went to the link and then bought lol

hopefully i got the right one as when i used the other site to get it for me i didnt see any option for ac or dc.. not even sure which one i have lol.. all i have is a code number on my old one

dont think i have a wiring diagram for it

I think I once saw a wiring diagram for your bike, and it utilized a DC-CDI unit. However, my memory might be incorrect. ;) Did you employ an agent at TBTrends? If so, he might ask you whether you want an AC, or DC unit. ;)

Spud :)

[craig1979]

Yeah I used tbtrends to buy it so hopefully they ask

Is there any easy way to find put which one I need or know where I can find a wiring manual

Cheers spud

This is the wiring diagram I found searching the internet. ;)

This diagram indicated the ZS250GS employs a DC-CDI unit. My Zongshen 200GY-2 employs an AC-CDI unit, so this is another difference between the two motorcycles. ;) I wouldn't be surprised if the CDI unit you ordered is only available in the DC version.

Cheers spud.. At work so couldn't search the net :D

You're welcome. :)

It's very possible your problems are caused by another electrical component, or are not even electrical in nature. However, if the CDI unit doesn't solve your problems, we can certainly help you to methodically find a solution. In any event, you were still wise to purchase another CDI unit. ;)

[craig1979]

nothing to report yet lol.. still waiting for the cdi to reach taobao so they can send it to me

hate waiting

[Corvairkid]

what a mess it was all hacked up electrically and i thing mine is 12Vac as when i test most of the curcuts i get a -12V flashing to 0V and back to 12V i went to a local dealer in my area who claims to have the cdi box but i have to wait a week for delivery but yea no spark at all on this junker but my coil checks out and so does the spark plug on my lawn mower.....

[craig1979]

Thought i would charge my battery as the cdi unity is on its way

turned the kick and bam bike started first go... really lost as to wether is cdi unit has fully failed yet or something else is causing it to shut off once hot

just need a new chain to be able to take it for a short ride

[katoranger]

Don't ride far from home. CDI boxes are known to start acting up after they get hot. Sometimes you will just get rough running, sometimes they totally shut down and then you can let it cool off and it will run again.

[SpudRider]

I suggest you listen to Kato. ;) CDI units are notorious for intermittent failures, especially when hot. If you keep riding the bike, a failing CDI unit will eventually die altogether, frequently stranding you in the worst possible place. :( Replace the CDI unit with a new one, and see if the problems disappear. ;) If the problems continue, you need to fix something else. If the problems disappear, get another CDI unit. Having a spare greatly facilitates troubleshooting the electrical system, and allows you to ride instead of waiting for a spare to arrive. ;)

[craig1979]

Well now im really pissed off.. got my cdi unit in the mail, plugged it in and turned the ignition on to start the bike

all of a sudden i could smell a burning smell, looked down at the cdi unit and all the wiring was melting, when i touched it it was hot

so now i have a cdi unit i cant use and some wiring to fix

[Corvairkid]

i hope that doesn't happen to me i just took my stator apart and cleaned it and discovered it was a wet stator joy now i need a gasket and btw still no spark here either....

[SpudRider]

Egads! 8O
