I’m ready to buy a new carb for my 1980 CR125 I’m building. Someone commented that these carbs are like discovering sex for the first time. Can anyone give me first hand feedback (the carb, not the sex).
Probably more of a case the bike runs with it on there and didn't with the worn out, clogged, broken stock carb so it's better?
I'd consider a Keihin PWK airstriker, unless there really is a X files style government coverup i'd say there is good reason almost every 2 stroke made today comes with a PWK instead of a Lectron. I've been looking at pictures of factory race bikes for years and never saw a single lectron mounted on one...
But as Newmann stated it would be illegal for AHRMA and their 300 page rule book. Even though my 86 CR came with a flat slide PJ they say the PWK is illegal.
And Joe, I haven't had any issues with the "legality" aspect. I've run these bikes thru Mid Ohio (AMA) tech the last 2 years with no issues. Also a couple Ahrma races as well,although admittedly we try to avoid those races because of the poor turnouts . (no fun running a 1 or 2 man moto,lol)
And to address the rules a bit more, Rocky, maybe the Lectrons don't get picked on too much because they were actually built and available back then, while the PWK was not.? The Lectrons certainly seems to fit in the loophole rule of modifications that are "period correct" as the rule states.

Yup, that is quite often the case, plus the placebo effect, "I read the manufacturers ad and it said that this carb will give me 50 more hp on my z50 and I just paid $400.00 for it." Some people simply fool themselves into believing something that is new and that they paid a boatload of money for must be better. I f they on;y paid $10.00 for one of those carbs and it said "heche de china" on it, they might not think it is as good as if they had paid $400.00. I see this stuff all the time.
There is one sure way to go faster, and that is to learn how to ride better, and a new carb ain't gonna do that for anyone.

I love guys like this, All knowing smackoffs that probably couldn't jet a Mikuni if their life depended on it,but all too quick to bust someones balls on how to go faster. Reminds me of the same type of asshats that tell guys they are stupid for putting some titanium on their bikes instead of going to the gym and lose some weight !!
And "Barnett" -- if you haven't ever tried a Lectron ,PARTICULARLY on a vintage bike ,you should actually spend a few dollars and hours to check into it, before spout out asinine advice. 40 year old 2-strokes with no power valves are no picnic to keep jetted properly.
Anyway, thanks for the insight. They sure sound interesting.
And oldpro288, you beat me to it. Thanks.
I'd ask a well known Honda engine and parts builder that is on this forum his opinion and if your curious still, get one and see if the goods live up to the hype. If you don't like it punt it on eBay and get most of your coin back out of it.
Tbteam-- back to the matter at hand. If you buy a Lectron and do not think it was worth every penny, PM me and I'll buy it from you for what you paid. I just don't believe you'll find an easier way to make your bike run cleaner with FAR less hassle. Just trying to answer your question with real-life experiences.
Well since your comments to me were childish, I naturally assumed your were young.
"Go give your advice to someone that actually asked for it."
ummm...that's exactly what I did, and then you tried to appear like the arbiter of all carb knowledge to satisfy your needy ego, and feebly, but amusingly, attempted to berate me and discredit my post in an attempt to make yourself feel like a "big man" in front of your internet friends.
"pffffft idiot LMFAO"
It's good to see that you recognize at least one of your better traits and are highly amused by it as laughter can help you feel better about yourself.
I also have experience with a tillotson carb which is what we tested on Jeff Jennings bike around 1975 when i worked at norm reeves honda motorcycles. Also, jetting a bing is no hurculean feat. I had them on both my 250 and 360 bultaco's that i raced back around 1975.
To your apparent dismay and surprise, your opinion and "experience" are not the only one that matters.
Anytime you can spend less time tuning and more time riding is a huge plus for me or anyone that works for a living and has limited free time to ride. OR when you have the ability to go up or down one,two or three sizes on the "main" jet circuit while you're sitting on the gate by turning the power jet even with your gloves on is a pure win . Does that happen often ? of course not, but its just another way of saying how easy these things are to tune.
Tbteam--good luck and my offer stands. You will not be disappointed.
I like that approach much better cuz nobody wins a trophy for being right on an internet forum, and even though i know a boatload, i still don't know it all and never will, but also haven't ever run across anyone else that does.
My point, which unfortunately got lost a little, was basically to suggest that the lectron won't make a "dramatic" difference in power or throttle response over a properly jetted old school vm style round slide mikuni or kehin etc. I wasn't saying they were not good or not easier to jet etc but i run into many cases where people are hoping like many of us do that some easy to bolt on part is going to make a big improvement and was just trying to get the point across that it won't and there may be a better place to spend that money.
Do i think they are neat carbs?...yes. Would i like to have one?...yes. Would I personally spend $350.00 on one?...no, and that is because in my particular case, it won't help me much, besides, i guess i'm kinda stubborn and prefer a bit of a challenge in tuning a vintage carb, plus i prefer some vintage stuff over newer stuff even if the newer stuff is obviously better.

"If you give Dave all the pertinent details of the bike/motor mods/ how you're going to use it/where you're going to use it,what fuel ,etc,etc., he'll set it up to fit correctly, use the correct metering rod and set the power jet. And every single time its dead nuts spot-on."

Now If you really want to start a carb argument get some hard core Maico guys arguing about Bing vs Mikuni....
I had bings on my bultacos and they leaked and worked just fine. I put a mikuni on a my 1974.5 aldolph weil 400 maico and it worked perfectly (once it started) and good enough that i won the ahrma western vintage expert open class and over 40 vintage open expert class with it in 1993, so i can't imagine a bing being any better, but i wasn't a hard core maico guy either and also had a 74 cr250, 74 cr125, and a 74 yz250 i raced that year and they also had mikuni's on them.
As far as having to change jets more on a mikuni vs a jetless carb or it being easier on a jetless carb, that's for sure but i for one don't mind changing jets.
Working for kawi r&d, racing pro motocross winning races AND professional quad racing as well?
You're soooooo good
