Son has an 02 CR125, bought an airstriker for it from a fellow here on vital. Got it working way better than stock, but still fiddiling with jetting. The Lectron supposedly is self adjusting, but is it as good performance wise? Would love to skip the jetting sessions if it's a good product, anyone got experience with both? Thanks in advance.

Even after adjusting the Power Jet?
Just installed a Lectron 38HV on my 2004 KX125. I'm basically a pure motocross rider to put things into perspective. Sunday i went to Cahuilla Creek to put it to the test. On a 125, Cahuilla Creek is basically WFO nearly everywhere on the track, and is sandy in some spots which loads the carb very well.

My initial impressions are that the bike feels "softer" than my well tuned Mikuni. Power is just smoother and consistent, rather than explosive. Admittedly i have only made some minor metering rod and idle screw adjustments and haven't yet messed with the powerjet. As my bike currently sits, it seems to have lost a touch of overrev that was readily available with my Mikuni. I'm going to try to see if i can dial the powerjet in some, but honestly i'm a bit underwhelmed with it right now. Just about the only advantage in my case at this point is the bike idles perfectly with the Lectron, where i really struggled to find a good idle setting on the Mikuni.
Going to give it some more time and make some more adjustments to give it a fair chance. Hoping that I can find a great setting and then never have to touch it again.
The Keihin AG Short Body is a solid carb, but just like any carb, needs fine tuning.
Not sure how the self tuning myth has come into such frequent mentions online.
But regardless, i'd never fire up my motor cold and rev it like that. The startup clips in that video were on warm engines.

There are about a dozen of my friends who have purchased the Lectron and all but one is happy with them, and he’s not hating it, but he said he wouldn’t buy another one. On the other hand, a few of my friends have bought more than 1. Bikes range from 125’s, 250’s, 300’s and even an older Honda CR500. Some off-road, some MX, all with great results.
In my opinion, the Lectron May have taken away some of the hard hit that some guys like. They tend to smooth out the power and make the bike a little less of a handful. They aren’t for the very one, it’s a personal choice. But that doesn’t mean that they aren’t for faster riders either. Just take a look at their Instagram page or the results of the 2-stroke Nationals last weekend.... There were several of the faster guys, including the top 2 in the open class. (Wageman and Gardner) Bowers 500, along with Cody Schock and Mike Browns YZ250, had a Lectron on them.
LaFountain and a few others were running them too.
I’m not sure how many guys had them on at RBSR, but there were several. Carson Brown and AJ Cantazaro had them on the 125’s. They were 1st and 2nd on the podium. There were a couple in the open class too. Hell, even Bill and Chase Elliot run them... lol
My point is that they do indeed work very well for some (including very good pro caliber guys), but the way they change the power delivery may not appeal to everyone.
There’s a lot of people that buy a used one and put it on a bike that it wasn’t intended to be used on.They have different sized bodies and different metering rods. Get one dialed for your bike and you will be a believer....
I ran a lectron 38 on my Husky CR165 (125 big bored) and it was great. It did lose a little snap off the bottom but it felt like it gave the bike an extra 1000+ rpm up top, huge gain! The only way the Mikuni even came close was running oxygenated race gas with a ridiculously big main jet. At $35/gallon, and guzzling it. The Lectron had even better too end power just running C12, and only using about 60% as much of it.
It did take some tinkering to get it perfect, by means of a custom metering rod and shortened power jet tube, but the guys at Lectron were very helpful.
I tried the same carb on 3 other bikes and had issues with all of them, I should have sent it back to Lectron for updated and reconfiguration specific to these other bikes but never got around to it.
I loved how easy this carb was to adjust. Loosen clamps, rotate sideways and pull out the slide. No need to remove from the bike to get inside the float bowl, ever.
DYno ?
Have te250, dont want a failure...
No comments from lectron ?!
Also your theory on cold starts is backwards. Why do cold engines want to be choked? They need more fuel....aka lean on start up. An engine that fires right up perfectly cold is most likely going to be rich when at operating temps. Nothing to do with fuel temps.
