Steve's CFMoto 650 NK（春风 650 NK）

[Steve_Halt]

I rode my buds, and he had drag bars with end cap mirrors, I hate the look but there was almost no vibes that came thru the mirrors, and they were actually usable without having to pull your elbows in....

Also last night I ran my NK on the 1/4 Mile race track here...Having no experience, a horrible reaction time, and riding the clutch alot outta first she still managed to pull 13.68sec. I only got one run as they closed it down but it was fun and I was proud of the wee lass.

Dragstrip sounds like fun :) What mirrors does your friend use? What's the brand, I mean?

He said they were just cheap Ebay Bar end mirrors... And the Drag strip is always fun. Even tho I lost to an R1...by alot... haha

bar end mirrors - not a fan myself... to easy to knock or be knocked and a hindrance to lane splitting. One of the key issues, is that nearly all MCs have weighted bar end inserts... these are functional aside from balancing the bar, they assist with dampening vibrations transferred through the bars... not sure if add-on bar end mirrors allow for the retaining of the OEM bar end weights. If not then to my mind - FWIW not good...

and... YMMV!

I have been looking for a solution to the problem where the water from the front wheel splashes onto the radiator and evaporates right into my face. That's massively uncomfortable riding in / after the rain.
I've been thinking of a mudguard extension, but there is none manufactured for 650 NK.
So I noticed that the front mudguard on 650 TR is much bigger than that on the NK and extends lower than the the radiator's bottom edge.
Surprisingly, there are not so many stores on taobao selling TR mudguards. I got mine from here:

Since TR's don't come in blue, I got a grey one, which will at least match my forks and the bottom of my tank shrouds.
This photo shows clearly how much longer the mudguard from the TR is:

The installation was pretty straightforward, no mods required. The end result reminds me how a Suzuki GW 250 looks.

Not so long ago I purchased a top box rack for my 650 NK and ... installed a top box. Well, after less than half a year the thing snapped at the weld seam. Good work dear unknown Chinese manufacturer!!!
I haven't loaded the top box with anything heavy. The heaviest thing I ever carried was my work backpack with a laptop and a folder in it. Way under 5 Kg.
The top box was removed immediately and installed on my Benelli scoot.
I put the passenger grab rails back onto my 650 NK and have it in the original state now.

I have always found these points of fixing to always to be the weak link , I for one add some more weld at these points and have never had a problem even with the top box loaded up , a quick fix , but should we do it ? depends on ones point of view?

[Steve_Halt]

prince 666, I will surely fix this. I just don't think I'll need a top box on my NK 650 any time soon :)

Also be careful of the woefully poor rear tabs welded to the sub frame, they won't stand up to much weight. The front tabs are fine however.

ZMC888, right!

I have been having the red EFI warning light for quite a time now. A trip to the official dealer resulted in the local mechanic explaining it to me that my TPS sensor was cracked, which resulted in a set of ECU errors.
Fine. So taobao didn't have the sensor itself and I splashed on the new (butterfly valve drilled) throttle bodies assembly (with a TPS sensor on it for sure).
The replacement process was relatively simple: tank, air filter, air filter seat, there you go. On a side note, I didn't like it how the bike's wiring loom is routed. On top of all, the fuel pump (or whatever that is that goes between the tank and the throttle assembly) was not hanged on its holder, but was just there on the engine. Sticking it where it was supposed to sit explained to me why the assembly guys didn't bother - it s a pain.
Anyways, I installed the new throttle bodies, hooked everything up and it worked OK. Except for one thing - the red EFI warning light is still on.
Restarting ECU (ignition off - WOT - ignition on - EFI light - throttle closed - ignition off) and unplugging the battery for 8 hours resulted in nothing.
And, starting yesterday, the sensor is sold separately on taobao for 150 yuan (much cheaper than the 990 yuan throttle bodies' assembly).
When I rode the bike home, I noticed popping noises in the airbox on deceleration. So... Was it not a faulty TPS after all???
A bit of googling resulted in the following: those popping noises mean that the mixture is lean. The thing responsible for mixture quality in FI engines is lambda sensor (oxygen sensor). My bike has 2 of those. They run 550 yuan a piece from taobao. A malfunctioning lambda sensor can screw the fueling badly and result in ECU errors.
I am mightily disappointed at tis moment.
