Overall it looks good and the price is right, but I am frankly concerned about the long term reliability of the EFI system and components, as well as wondering what can be done if you decide to add aftermarket filter and pipe ( catless ,etc) which generally requires a reflash and if anyone will step up and offer that service.
Still , it is encouraging to see the Chinese Bike market make the first step into more modern offerings like EFI ,inverted forks, adj, rear shocks and still be new for under $2k.

They’ve long passed this type of bike and due to lack of interest in such a basic model have long progressed on the bigger n better What you’re seeing is up to 5 years old tech or more in chinatown |

Nice video! Thanks for the post! I didn't know motocheez bought one of these.
comments....the screws that go into the fuel tank, should go into a blind flange. Motocheez did a nice job of making the fiber washers. The original orings, could fail at a later date, and need to be replaced with fiber washers. A video cd attached? Nice step up! Also, motocheez found the master link on the bike was not installed properly. Good video! Thanks for sharing!!!!!

Glad they used Delphi electronics! I would think it would be pretty reliable. Would think that a elevation change from like sea level to 5,000 ft. would shine on this bike for performance.

why they have a few sencers in the system.. If not you can do it manually as you ride for a bout $5 worth of bits.. Adjust the A/F ratio at the turn of a nob...

Yes that would work at below 6000 RPM, above that Delphi runs of its own map etc. Also the ECU would compensate back to desired AF even if you trick it into thinking the Air Temp is lower (self learning). Funny thing is this EFI is even a bit better quality that is found on the GPX or PitsterPro which has a cheap DIY style Rojo EFI. My RX3 and many bikes sold in China use Delphi as so do Briggs and Stratton mower and several other small engines upto 2 cyl. If you look at the RX3 threads you get some more info BUT I haven't seen much about tuning the ECU and that I believe requires expensive gear etc. No I never did anything with my RX3 ECU it is stock yet has a big bore. The DLX has a Delphi made ECU but other parts are not Delphi made but compatible (maybe injector is Delphi maybe not) |

1 ohm pentameter....
wired into the air box temp sencer... you tell lies to the ECU about how hot the air is... Tell the ECU the air is hotter " lower O2 level " it will lean the A/F ratio... Tell the ECU the air is colder " higher O2 level " it will richen the A/F ratio.. On my XT660R I can hear the engine note change while idling when I turn the nob... ..

Correct BUT........ That would only work when the ECU looks at the Air temp so below 6000RPM, also the ECU would be compensating as it would sense from O2 sensor the real AF. So it would work often to a point but ECU would try n trim back to target AF to 14.6 (I think that is what Delphi commonly set theirs to be). It should give some benefit but wonder if it is as stable as it could be - also if AF is set good it would run just fine etc. I know they sold these type of boxes for many bikes using the same method in tricking the ECU but I haven't tried it my self. |

They would be better off trying to get Zongshen to create a new bike while continuing sales on the TT250.

Upgraded charging system and a much better placement of the reg/rec is nice to see.
Re-routed and shorter spark plug wire to stop it melting from the exhaust is a nice little upgrade. That rattling clutch bothers me. That indicates that some of the clutch discs are sticking due to sitting without the oil making sufficient contact to prevent corrosion. That is a concern to me for early clutch failure. Stainless steel exhaust is nice, although I am curious about the catalyst. Also kind of annoying that they use the same thumb screw clamp that likes to vibrate loose. I suspect the speedo is still rather optimistic, but now in digital! At least it has a tach. Quote:
Honestly, if I were going to spend $2000 on this, I would just spend the extra money to get the TT250. I am silly that way. A more complicated machine for less money sold by a company notorious for screwing people with warranty claims, and still likely plagued with the same quality issues (the seat is a great example).
