Welcome to here! Have you looked through all the cfmoto threads? Not too many people as of late have posted anything about them. Do you have photos (of the bike and Chile)?
not yet, ill take a few on the week ;)
Martislash, Hi and welcome,
650NK, I've got one and 13,000 on it now. Read my thread or maybe read Steve's thread.
Certainly check the torque specs on all bolts, and keep an eye on everything, including clutch cable. Run it in carefully hot change the oil ASAP with a filter change to high quality mineral oil, change again on 500km or follow the guides.
you mean change it right now? or at the 1000km revision? why mineral?
thanks!
Hi and welcome to MCM.

If you want/need to search for information about your model MC etc, know that there is a search engine window near the top RHS of the MCM webpages.
Sometimes though one can find more relevant search results by using the Goog.le search engine by simply adding the word(s) "mychinamoto" to your search.
Couple of links that might be useful/relevant.
CF650 thread includes links to both TR and NK threads on MCM... both models share the same architecture, but different skin.
Running in a new engine
Look forward to seeing some pics of you MC, cause 'this thread is useless without pics'...

Martin, soy Gustavo de Argentina y administro un grupo de facebook de las 650 NK, te invito a que te sumes y alli encontraras la informacion que necesitas, yo tambien te recomendaria que cambies ya el aceite y luego a los 1000 km. El aceite que mejor va en esta moto es el semi - sintetico, un 15w 40 como pide el manual. Este es el grupo en facebook: https://www.facebook.com/groups/kellerk65/?fref=ts

I always heard that mineral oil was actually better for your engine for some reason. Could be an old wives tale though...Quote:

This "polishing" is intensive in first couple thousand kilometers and you, as guy who uses this bike every day, can feel that during that period, engine runs smoother and smoother every day, not running hot, even getting quieter and geting some extra ponies. It is some sort of controlled wear which increases some clearances in order to reduce the internal resistance and optimize your engine's running. Hi-tech oils with tons of aditives or purely synthetic oils doesn't allow that.
Well, I didn't wrote something new - we all are C-moto riders and we all are aware how much proper old fashioned break-in means to engine longevity.

here it is, ready for a weekend travel :)
^Nice. I like the blue colour - very photogenic IMO. Seems you have a nice set of soft luggage there. Is your NK an ABS model (can't tell from the photo)? Any plans to change the rear muffler?
On a side note FWIW, I was in the local KTMR2R & CFMoto shop last evening (Ningbo), having a cursory browse at different bikes. On the KTM side of the shop, there were a number of Duke 200 & 390's, one Duke 690 (plated :eek2: ) and a Duke 1190. I noticed that several of the Duke 390's and the Duke 690 had fitted Laser mufflers. IMO the addition of the mufflers looked to be an aesthetic improvement over the little muffler. On the CFMoto side of the shop, there were upwards of a dozen 150NK ABS models, one 650NK ABS, and a couple of other 125 models. No 650TR in store, but a few 650TR ABS models are expected shortly. I did like the 'look' of the NK, seemingly subtle design improvements over the older model - but each to his/her own.
Look forward to seeing some photos of your weekend 'rides' :popcorn:
Would love a rear muffler change and eliminate the catalytic, could you point me to a good muffler not so expensive that fits the cf? im in chile so i would need intl shipping , thanks ;)
It doesnt have abs, on fact i had no idea that it was an abs version
Laser were manufacturing here in the mainland, actually they were within 10km of my location here, however they moved round Dec '13 from XiaPu, to somewhere near Beijing. Irrespective if they are still manufacturing then their local labour costs should reflect a somewhat lower retail price compared to some other after market manufacturers. Does Laser have a presence in Chile? Even if not, then do you know anyone from Chile who is in China or travelling back and forth between the two countries..? There are other brands e.g. IXIL - which are fairly common here (I have a hexagonal design IXIL on my 650TR), and some would say there are 'better' brands too.Quote:

You can find some threads detailing some of the NK & TR's where owners have swapped over the muffler, myself included. Use the links provided to you on page 1.
Yes, ABS (Conti) fitted on the late 2014 manufactured 650NKs, 150NKs and 650TRs... I suspect you have an older model...Quote:

Foe example would that work on the bike? adapting the mounts of course
Search for a Kawasaki ER-6F after-market muffler... since the Kawasaki and CF650's seemingly share much of the same or similar 'design parameters'
The big catalytic converter underslung the main frame, needs to be removed... so the fitting of any after-market muffler isn't exactly a slip on as it takes a bit of labour to get the catalytic converter dismounted and the after-market muffler on...
Marislash using any muffler from a Chinese website is IMO not a good idea. You'll likely lose power almost certainly lose torque and ruin the fuel economy. The bike will sound louder and be more aggressive but the performance 'upgrade' is purely psychological. However an ER6 muffler might work on a 650NK, but you can't be sure as the bikes have different electronics and engines. Also removing the cat is illegal in most countries as well as environmentally irresponsible, also it is not a slip-on job, so you need to go to quite extensive money or time consuming work to reverse this modification every time you take the bike for government inspection.
If you want to go quicker a trying to modify a CFMOTO 650NK is not a great idea, it's kind of fine as being a middleweight cheaper kind of bike, really you're lucky if it stays reliable and glitch-free. Screwing around with the fueling, air or electronics plus all mods are very second rate and not well understood or proven and IMO not advisable. If you want more power it's better to begin with a bike like a CBR600, GSXR600 or something as all the aftermarket exhausts and power commander mods are well known and understood, and the bikes have a higher level of manufacture quality to build from.
Anything you do or anyone else does is up to you, this is just my opinion.
As ZMC888 advises beware cheap no name mufflers, especially no name mufflers from Ch!na.
However, lots of motorcycles the world over have, have fitted after market mufflers seemingly without negative consequences.
I've a Akrapovic on my Super Tenere (S10) 1200Z and it runs fine, passed safety inspections without issue and like many other S10's the fitting of a branded after-market muffler works wonders based on the posts on a number of ADV and S10 specific forums anecdotally suggest.
I've a IXIL hex shaped muffler on my 650TR and it runs fine, passed the local safety inspection late last year, including the exhaust outlet gas emission test analysis - which fell below the EU-III maximum levels.
A friend has a Yoshi muffler on his 2006 TMax scoot, and it has runs fine without issue, and the scoot has passed several safety inspections.
Buy a quality after market muffler, here are just a few brands:
Akrapovic
Two Brothers
IXIL
If after-market mufflers were an issue for emissions then the companies wouldn't be in business. Some manufacturers even offer after-market muffler brands as an upgrade option at point of sale through dealers e.g. Suzuki, BMW, Kawasaki et al.
You could buy a Power Commander and visit a tuner with a dyno, but many motorcycle owners don't.
Do a search on you.tube, and you should be able to find a few 650NK videos showing muffler mods.

-Almost everyone that is not a complete idiot (where I'm from) only do specific mods for specific bikes. eg they buy a CBR600 power commander and muffler for their CBR600. They don't buy a CBR 600 power commander and exhaust for a gixxer 600 as it might be 'similar'.
-If you remove a CAT from a bike how the hell is it legal or how can it pass emissions tests?
-'Runs fine' is an opinion and not factual data.

I wrote of my experience having removed two CAT's from two different motorcycles... S10 and 650TR, and both motorcycles passed emission tests in two different countries... that is fact! I didn't comment on the legality of my decision.
ZMC888 you have your stated position concerning after-market mufflers (of which I am well aware) and I have mine, but don't get personal about it (I note you edited your post since).
You are entitled to believe what you want.Quote:

The thing is with the NK and TR CFMOTO 650s this is unproven territory, and possibly damaging to the bike. Unless you are an expert, I would suggest to leave well alone, as honestly it's just not worth it. Wondering whether the bike will hold up to normal use is question enough. Then we have the fact that, sure it isn't the quickest bike out, but really on the street is anyone that good that they really need an extra 1-2KW on top of what the bike has already? Sure extra power would be nice if you are doing track days, but suggesting someone start and throwing money around for 'experimentation's' sake just seems like bad advice.
After riding the Doc's TR and comparing his to mine, his bike with the after market exhaust "DID" have more low end grunt! Remember that was after I have ridden my TR for over 13,000km and I rode the Doc's bike for more then 2,000km.
Yes and the Doc's bike had a little more noise from that IXIL exhaust hehehe but it's not obnoxiously loud, but being louder is not a bad thing at least the dic- heads Chinese people can hear you coming!
I do agree to get the full potential out of an aftermarket exhaust you DO need to re-map the ECU!!
There are literally thousands of Harley owners that pull of their quiet stock muffler and slap on a drag racing style straight-thru muffler. They swear that the bike has more low end grunt and more top end power, sounds meaner and so is also safer. The reality is that when the bikes are dyno tested the same bikes are way down on torque and a tad down on power.Quote:

Most of that tuning for torque is done in the muffler with back pressure. Someone with a new bike has a natural temptation to knock through that 'horrible restrictive muffler' and let the bike breathe, but this is actually a mistake in most cases. Although I would admit that carbon build up in a stock muffler or cat will eventually start to strangle the bike after a few years.
The answer is simply that most likely it's not worth recommending someone spend loads of money on something not designed specifically for their bike especially in the first 20,000kms or so, gains are minimal, retrograde or potentially damaging but to be fair it's unlikely that you can put off a petrol head obsessed with having more power from trying.
Yes ZMC888 you are right - people think because it sounds better therefore it "goes" better this is commonly a fault of most people's understanding but it's fair point.
I feel that I know my TR after 13,000km. How it pulls in each gear and at what RPM!!
I found that the Doc's TR was pulling as much as 500rpm lower to get the same result from the engine IMO that equates to more Toque from the engine.
Based on these results I think I can confirm the Doc's TR with the aftermarket IXIL exhaust had more torque?
Maybe the curve has changed with more initial torque and then a flattening further up the power-band. Maybe there is a gain in power and torque at the expense of fuel economy. Just guesswork without a dyno.Quote:
