Where can I download the "service manual" of the 650NK?

Where can I download the "service manual" of the 650NK?

If you go to the cfmoto.cn website, you can download the 650NK user manual which has some basic maintenance information including the maintenance schedule.

http://www.cfmoto.cn/download/20-1.html

I also have the manual and have edited the index so that I can select the relevant page I want to view with one click of the LHS computer mouse button rather than rolling through all pages of the manual.

If you want it, send me a PM and I will upload it or otherwise I'd send it, but the file is 8mb so if you PM me your email addie, make sure you can receive attachments of 10mb.

Hi there, first post.
I found this thread by doing a search - I am pretty sure the ECU on my GT150 is dead but I'd like to do some tests to make sure. The links to those files are dead, are there any updated links for them please?
FWIW if the ECU has died, then it's the 2nd one it's killed. I have no idea why.

Error Codes

How to read CFMoto EFI/ECU error codes
Error codes are shown on the red F1 “EFI” light. This has a icon overlaid on it that looks vaguely like a fuel injector spraying some fuel if you use your imagination. When a fault is detected the light will illuminate for a few seconds then begin displaying a series of long and short flashes. The long flashes are the first digit of the fault code, the short flashes are the second digit. By counting the flashes you can figure out what the code is.





It is usually possible to clear errors by disconnecting the battery for >10 minutes.

Once you have worked out what error code is being shown, you can get a definition of the error from this table:

Hi Bundypig .....


The 15 Flashes means it needs a Service.

If you take your bike for it's service then they will reset it .....until the next service is due.

If you are doing your own servicing then if you search you will find links here to how to reset the error code. BTW there are a number of alternative ways to do it. Just need to try them until you get one that works.

Hi
Would anyone happen to know what 6 long flashes and 7 short flashes means is wrong ?? It’s not in the error code tables ..it’s for a 650 tk ....the error always comes on only once the bikes is warm ....if I’m idling when it comes on I notice the idle drop slightly then normalise just before the the error light comes on ...sometimes it backfires through the air box but that’s rare.

Thanks for any help!
