Does the cf moto 650 nk 2013 use a lot of oil I have topped mine up twice since getting it a few weeks ago can’t see a leak wondering where it’s going tif
1 answer
No it should not , get it checked out , mine has not used any ( apart from oil changes ) in 40,000 km

Contact CF moto Australia. I purchased a CFmoto 650NK Brand New in 2013. The bike has only done 9500 km and I have been happy with it up until a few week ago. Unfortunately issues started to arise recently and (the dealer) kindly tested the ECU off another machine and the issues resolved, confirming a faulty ECU. Dim neutral light / no speedo / misfiring etc. Earth cables tested etc. The bike has low miles, dry ridden only and garaged. I am now expected to have to pay out $800 for a new ECU that should last a lot longer than 6 years on a brand new machine. Should this be a free exchanged or on a warranty issue by CFmoto or do I need to pursue this in another direction as I cant ride the bike at the moment or afford $800 (25% of the bikes value). Anyone else had this issue ?
1 answer
Hi Jon. Sure have. A common issue and CF MOTO does not want to know about it. The dealers are just as bad with dealing with any problems these bikes have. When the ECU was changed out it even had damaged written on it from new meaning it was I stalled that way. Apart from fuel tank leaking from new, the Continental front tyre blistering at 12,000km and the hand grips melting the bike is still running. Shaun

Hi folks I've got a 650nk and I've a red light warning flashing on some times on dash . It's not oil anybody know bike is going find?
2 answers
Maybe a sensor error, you'll need to take it to a dealer to check the computers error and they'll let you know what the issue is.twist the throttle to full on and hold, turn ignition key on, wait until light flashes once and release throttle and turn ignition off. That should clear any fault/service reminder codes. If the issue returns, depending on the sequence and length of the flashes you can determine which fault code is being highlighted. Cheers.

Has anyone had any trouble with the neutral light saying on and the injector light flashing?
1 answer
Hi Sut, it is best to get in touch with a CFMoto Motorcycle Dealer to inspect your bike as it is hard to diagnose with out physically seeing it. If the injector light is flashing constantly it could simply be the service light reminder. If the bike is running correctly and the neutral light is stuck on, this could be to do with the neutral light switch. Again these are only assumptions as I do highly recommend that you get in touch with a dealer. To find one please head to www.cfmoto.com.au

I have a 2015 nks which throws error code 47 oxygen sensor 1 I’ve spent 900$ on these oxygen sensors and plugged them back in and still throws the error code. Doesn’t hinder while ridding but as soon as code is on and flashing while ideling it sounds like something faulls and then it spits and splatters in idal. I’ve ripped apart the bike Checked all wires back to the ecu and also changed spark plugs. I’ve contacted a dealer with there reply of they are unsure as well anyone else have this issue?

Hi Shannon, thanks for the question. I encourage that you take the NK back to your dealer and have a mechanic to further investigate the issue you are having.To cancel the error code. 1.Turn the throttle wide open. 2. Turn the key to on. 3. Wait till the Fuel Injector (FI) light lights up with one flash. 4. Flick the kill switch to off. 5. Let go the throttle 6. Wait for about 40 seconds. 7. Turn the key to off. 8. Flick the kill switch back to on. Restart the bike and the error codes should be removed.I have the exact same problem. 2013 650nk. Error codes 47 and 48. Changed both O2 sensors. Neutral light on dash is dimly lit. Stand can be put down while in gear and running and doesn’t cut out the motor... usually runs rough between 3500 to 4100rpm. Might be TPS but can’t source one to replace it....
