I recently got a 2004 Commando 250cc liquid cooled rear drive atv from a friend, and on the title under manufacture it reads QINJ. it is having a running issue and I would like to get more info on it before I start tearing into it. ,y friend had told me it was a Chinese made atv. please help

 

what's the issue? give us details on what it is doing and not doing and what you've done.

 

Its certainly a Chinese quad.. What do you need help with?

 

Hello everybody I just purchased a Commando 250 for $80 in a no running condition . I cleaned the carburetor and rebuild the starter now it runs but i can hear the gears grinding in the transmission .... does anybody know where I can purchase gears or anything else for that matter for this squad.. I have been searching everywhere and have not had any luck.. anybody with any information please reply I greatly appreciate it thank you so much

 

just Googled it and got this 200cc-250cc Water Cool ATV Parts | Chinese ATV Parts | Chinese Parts mentions CG200-250 which I think refers to a Honda engine, so may well be a copy of a Honda, though they are air cooled. Another Google hit is https://www.alibaba.com/product-deta...28d4183foRkbRs so the water cooled version is still available, which means spares for a Zongshen CG250 should be too.

 

Hey all, I also have a 250cc liquid cooled atv. My issue is that it has no spark.

I checked the ground at the coil and it's fine. There are 2 other wires that are connected to the coil.

I believe this atv has a DC CDI. It is double the size of the AC cdi boxes I've seen. It has a blue 6 pin connector housing with 5 leads inside. It does not have 2 separate connectors the the AC ones it just has one big blue plastic connector.

I believe the Stator and the CDI are working fine based on the voltage I pick up at the two wires supplying the ignition coil.

Here are the readings I found on the two wires supplying the coil:

- Black & red wire, Contant 12.95v DC as soon as I turn the ignition on

- Black & white wire, 0.12 - 0.23v randomly AC while I'm turning the engine over ( it seems like this is a pulse wire to tell the coil when to fire.)

Since I thought these readings were correct (at least I think but please correct me if there's something wrong) I moved on to measure the ignition coil resistance.

- Resistance between the 2 hook ups on the coil for DC & AC wires: 4.2 Ohms

Resistance from either the hook up (didn't seem to matter which one) to the spark plug boot: 20.2 K Ohms.

I thought these were within reason as well. But the ATV still will not spark.

I appreciate any help, I've been fiddling with this atv for 3 weekends now and I just want to get back on the trails.

Regards, Jack
