Hello! About six or seven years ago, when I first started working with metering rod carburetors, I had already heard of you. On my 2016 TE250, I tested almost every rod available, including 4-1, 4-2, 5-1, 4-2m, and 3-2m. I was particularly impressed by the performance of the 4-1 and 4-2m on the Lectron VH. I have great respect for the work you’ve done for Lectron in the past.
@@xtngcarbs1249 Good stuff. Thank you. Small world. I struggled to get the early Lectrons to work on 4 strokes. Starting and idle was always a challenge.
@@Motosportz This reminds me of the challenges I faced with the XTNG GEN1 4T version. As you mentioned, idling was a significant issue, followed by the precision of the metering rod. 4T engines are incredibly demanding when it comes to fuel accuracy. I made countless adjustments to the designs on the YZ250F and DRZ400 before finally achieving the best low-end and high-end performance. In comparison, 2T engines are much more forgiving when it comes to fuel precision. The journey has been a tough one, but it has helped me grow a lot. Despite the difficulties, it has been incredibly rewarding.
@@xtngcarbs1249 Two other things that come to mind about Lectrons was the overall physical size of the carbs (usually to big) and the hard throttle pull that I never found away around. Light return springs allowed the slide to stick. Have you addressed those items?
I've seen this same story since 1980 when a few Lectrons appeared on mx bikes replacing the round mikuni. They disappeared to drag racing as soon as the keihin pj carb came along. The pwk was the common choice and still is. I admire the development of this design but being more complex and unique isn't a good thing when you need a bowl oring or float valve on a Saturday before a race. K.i.s.s. is the best idea for any dirt bike carb and the pwk is just that. Remember,it doesn't always have to be better,it just has to be different.
Before November 2024, I fully agree with your point of view. After two years of continuous trials and improvements, I can say very responsibly that the comprehensive performance of GEN3+ far exceeds PKW.
In fact, the GEN3+ is very simple and reliable. Perhaps you've seen various different modes demonstrated in the videos, but in reality, the operating principle in each mode is very straightforward, and it provides a noticeable performance improvement.Thanks for talking anyway!
All metering rod carburetors operate based on the same fundamental principle. The only difference is whether they include a fuel pressurization system. Smartcarb, for example, comes with a fuel pressurization system, also known as an internal venting structure. Similarly, we also have this internal structure. On the other hand, Lectron uses an external venting structure. This means that their fuel pickup signal entirely relies on the vacuum effect created by air flow speed to pick up fuel. With this basic technical premise, we have added an additional fuel assist system, which you can think of as a pilot circuit in traditional carburetors. This circuit significantly improves engine idle stability, low RPM torque output, and throttle response. This is one of the features that sets us apart from our competitors. In addition to this, we can also add systems like the torque gain circuit found in the Lectron Billetron Pro, as well as the power jet circuit system. We also allow the parallel integration of Japanese-style solenoid valve systems, which our competitors do not offer. This means that when you own an XTNG GEN3+ carburetor, you are essentially getting the single-circuit system of Smartcarb and the multi-circuit system of Billetron Pro, with the ability to switch between them at any time, anywhere. This is something our competitors cannot offer. For the same low cost, you get more functionality. The choice is yours.
Also, I watched some of the riding videos from your channel yesterday. Is that you, the owner, riding or someone else? If it is you and if we can get a face behind the company you'll get more respect in the US market in my opinion. Riders respect other riders, you dont have to be the best just be an enthusiast. I also think you need to hire an American to help translate your videos and presentations. There are just to many subtleties that you cant get with AI when communicating. Im sure its the same when you hear english translated to mandarin. Your going to have to give product out to more influencers, I hate that word, on social media and RUclips to review. But you have to be careful with who you choose. Your facing a huge disadvantage being Chinese in an American market but if you can show people that you ride and are passionate about your product and have that translated in a way people will can easily understand. People here will respect that. One more thing if a 36mm is better on low end and a 38mm on top end, why not make a 37mm, nobody else makes one? I say these things like its easy, haha sorry. Anyways just some suggestions hopefully i dont sound offensive. Again hard to know without a proper human translater. Good luck.
Thank you so much for watching our video and leaving your comment. The suggestions you’ve provided are very insightful, and I fully agree with your perspective. However, due to the limitation of not being a native English speaker, I’m unable to deliver fluent English myself. I can only use artificial intelligence to synthesize the voiceovers in our videos. While I understand this approach can result in expressions that may feel awkward or uncomfortable for the audience, it is unfortunately the best solution available to us at the moment. I completely understand your point. As a Chinese company trying to promote a new product in the off-road motorcycle industry, we face significant challenges and disadvantages. What we can do is focus on making the best product possible, so that everyone who interacts with it can provide positive and affirming feedback-this is what we strive for. I will definitely take your suggestions into consideration and actively seek suitable collaborators in the future, including the influencers you mentioned. However, I approach this matter with great caution, especially given a past experience. Two years ago, we had some interaction with Morgan Spradling, the owner of Highland Cycles. Morgan expressed a strong interest in our product, and in good faith, we provided him with it. However, the collaboration did not go well. Without much communication or discussion with us, he gave a lot of negative feedback, emphasizing his so-called objective and honest review stance. Although we eventually resolved all issues, Morgan did not provide widely positive recognition for our product. Even though most people later agreed that the GEN3pro delivered far superior low-end torque compared to the stock carb, Morgan still insisted that the PWK was the best. To be honest, his involvement in that test ended up causing some harm to our reputation and image. Later, I learned that he had never liked any metering rod carburetors, including Lectron and SmartCarb. Regardless, I truly appreciate your feedback. Thank you for taking the time to leave your comment.
Will this fit on a 2013 t m e n 300 two-stroke it has a pkw 38 mm on it right now which works incredibly good I know I want the spray nozzle inside the carburetor to give it top end performance pkw 38 works incredibly awesome Keegan carburetor
The traditional PWK carburetor has many fans, but its bottom-end performance and top-end performance are indeed not as good as those of well-designed metering rod carburetors. Once you try GEN3+, it will definitely change your existing perception.
I did a ton of development for Lectron. This looks interesting.

Maaan, i love tuning carburators and this one will be one of my sweetest dreams to have.
What is the advantage of transplanting the solenoid? Power jet actuation from the cdi? Bike in question is a yz250
to retain the factory electronic powerjet where applicable I assume.

I've never ridden one of these carbs that wasn't lean on a motocross track.
Hope you get a chance to try it, I promise it will change your mind.
Send me one to test.
Ok, but how does it work then, not a word about it
