Re: Steve's CFMoto 650 NK（春风 650 NK）
I'd be almost 100% certain that the restriction for the LAM (learner approved) bikes when compared with the standard unrestricted bike of the same model, will have an altered ECM/ECU. Most likely it will be in the fuel loop tables within. Unrestricting the LAM bike would be a simple matter of having the ECM/ECU connected to the manufactured supplied computer module (via the dealer) or taken to some place like ECUnleashed <sp> to have the original ECM/ECU re-flashed if it is locked. A power-commander might also help in this regard. Obtaining a replacement ECM/ECU from CFMoto might be an alternative.
There might be some very specific conditions tied into the specific model certification for import that might restrict what the dealers can offer...
A manufacturer is not likely going to spend time on tooling up for manufacturing of two variations on the same engine for the same bike model, so mods to inlet/outlet valves, pipes etc are not what is needed to remove the LAM restriction perse', but the same mods when done in conjunction with the use of a DYNO etc would be useful to gain some HP out of a stock engine. Though having been down this road decades ago with a Vauxhall Chevette altered into a rally car... it is both time consuming, challenging, and drains finance's rather quickly.

Euphonius I believe the modification in Australia is to retard the bike down to a level which makes it similar in power to a 250, 20KW? Or to retard the bike to a 'provisional' power level maybe 50KW? At the end of these periods the bikes can be legally unrestricted.
An exhaust system alone will not improve much the performance, maybe 2 to 5 hp depending on the bike, adding a hi-flo air cleaner and re-tune the carb or injection should change things...drastically!

Yep you are correct, but only you're talking about specifically tailored and tested aftermarket exhaust systems for sport bikes. For example I could easily buy a specifically tailored dyno tested Yoshimura or Akrapovic exhaust system for a CBR600R, but shoving some straight-thru muffler a China bike will not help at all most likely no extra power, much less torque. It seems to be some kind of urban myth that anything you do to any stock bike will make it more powerful.

Yeah I'm sorry for jumping too ZMC. I have investigated the ECU issue too and was told by a guy that using a Power Commander V management system could very well achieve the desired result or better as it bypasses the ECU with the help of a dyno but the price of $800-$1000 AUS made it nonfeasable. Anyway my bikes in the shop having a cracked head seal replaced and its throwing up a injector sensor error so I haven't ridden for a while all under warranty of course so I'm a bit pissed off, though I have been riding hard lately. Still impressed with the bikes power even though restricted to 50kw I would still like the full 70kw or more. Euphonis you cant legally change the restriction because its stamped on the compliance plates as a LAMS not that that would stop me if I could figure it out. Anyway peace out people and ride safe.
Re: Steve's CFMoto 650 NK（春风 650 NK）
Awesome Guys thanks heaps for the info!
I've been back to the shop, this is what I got told, the guy had to say it in such a way that wouldn't get him into trouble, he basically removed the rear passenger seat and pointed at what I am guessing is the ECU and said "thats the little black box that keeps you learners safe, if you didn't want to be safe you'd wanna change that, but we don't / can't sell them as all bikes are under warranty so their is no need for replacement parts to be sold on these bikes as any failures are covered by warranty"
I assume basically that this is what holds the power back, it seems to have some truth because the LAMS bikes seem to be the only ones having any issue with fuel and rough idle ect, I reckon its because the factory wouldn't have spend alot of time optimising the ECU for LAMS, once they achieved the lower power output they require I reckon all other testing / changes would have ended. This is the main reason I would like to change mine, I feel that the "full version" bike would have better tested / advanced ECU management resulting in a more reliable bike possibly.
If anyone gets a way to confirm what I suspect or knows where and how to order one of these units please let me know :)
Also I noticed next to the ECU there is a cable with 3 wires which has a plug on the end, does anyone know what this is for? or if this is not found in the "full version" ?

Read my post above (edited). What the shop guy pointed to is the ECM/ECU. The cables with plug are what the computer calibration module plugs into, to perform a range of diagnostic, various engine management & calibration functions etc.
Re: Steve's CFMoto 650 NK（春风 650 NK）
Sounds like all you need to do is lay your hands on a stock ECU from CFMoto.
How long do you have to wait for the LAMS punishment to be lifted? Six months? A year? Or is it conditioned on your driving record? Further testing?
Re: Steve's CFMoto 650 NK（春风 650 NK）
Sounds downright totalitarian-ist.
Is there no way to check with the legal importers in Australia? Surely this cannot be the case -- a 650cc bike being permanently retarded to the performance of a 250cc bike. Why would you buy one?
To be politically incorrect about it, this would be simply fucking retarded!
Re: Steve's CFMoto 650 NK（春风 650 NK）
CFMoto are not alone "detuning motorcycle HP output" when meeting certification for LAM in Australian or other markets for that matter. Perhaps the differentiator is that CFMoto may not have any alternative ECM/ECU available due to not completely understanding the market or regulatory functions etc. - while other motorcycle manufacturers maybe able to offer recalibration of restricted ECM/ECU or replacement on LAM models, CFMoto haven't made this available as they might not have understood this or have the infrastructure in place. Alternatively some jurisdictions might forbid changing the LAM certified models regardless.
Despite this having spoken with CFMoto today, I can advise that at the moment, many of the parts for the CF650TR (CF650-2) are not available, from some replacement panels, fasteners and much of anything else aside from consumables e.g. CF650 air/oil filters, spark plugs etc. My CFMoto factory contact having supplied me with the 650TR part list has asked me to contact him in a months time to get the parts I want for the 650TR (I appreciate that we're discussing the NK model here)... just that I like to keep many spares for my CFMoto models in my garage for "those just in case" moments, and the 650TR is no exception in that endeavour.
