Thanks. Next weeks video has some different trails at this riding area that are really spectacular!

Really appreciate the candid review. Would be interesting to hear Lectron's response to your test results.

The exact comparison video I have been looking for! Good stuff!

My Billetron runs good. I also had a leak at bowl drain. Got a new bowl assembly from Lectron. You can tighten the bowl drain gasket from the inside of the bowl too. I do get a fair amount of spooge though. It's super crisp and smooth off idle.

I can only compare my Billetron to the stock 36mm Keihin PWK. First, I had to richen my Billetron 3/4 turn to find the sweet spot, after a full day riding I do get about a 1" drip of oil at the exhaust(running Maxima K2 at 60:1) but its where this engine is happy. As for power, the Billie gave me a stronger, smoother low-end over the Keihin. In fact on my first ride with it I got flung off some roots into a tree, because the power came on harder than I was used to.

Ho guardato anche il vecchio video sul Lectron, dovendo acquistare, dopo qualche dubbio di base, credo mi orienterò sul SmartCarb, per il fatto che mi serve fluidità ad acceleratore puntato. Grazie per l’analisi e il confronto, mi ha dato modo di essere sicuro che la mia scelta sia la migliore alle mie esigenze.

Sweet ride and vid bud - great day.

Is it true that crashing a bike with the smart carb prevents it from starting for like 15 minutes? I’ve read that a few times

I have also had leaking issues with the Lectron. First it was at the float bowl gasket. Then after getting a replacement carb from Lectron, I noticed fuel residue around where the drain bolt is located. I've gone 2 full turns leaner and still getting too much spooge but the bike runs strong. Will try even leaner to see how it goes. The main things I never liked about the Smartcarb is the installation (having to trim the intake flange) and the high price. It would be nice if it came with a pre-cut flange.

Interesting. I have a Lectron H series on my YZ250 and it pulls like a mule up hills at low revs.

Just a friendly piece of info: both carbs were basically designed by the same guy, William “Red” Edmonston. He invented it 1967 and Lectron sold it in 1974. GM later bought Lectron and “Red” left and ventured into a better carburetor that would become the Smart Carb. The Lectron has been largely unchanged since 1967. And the Smart Carb is drastically improved with a drastic price difference. Also, don’t spray your Lectron carb with brake cleaner. You will ruin the plastic. My friend did it to his. It stated cracking but luckily does not leak. That’s one perk I can think of with Smart Carb. The clear float bowl seems gimmicky. Lectron is $500. SmartCarb is $1,000. The Smart Carb is easier to tune without disassembly or tools. The Lectron is a bit more complicated. Keep in mind you only tune these once and basically leave it alone.

Lectron's new Billetron Pro (yet another power jet added), the model their lead engineer publicly touts as being leaps and bounds better than last year's Billetron, is the same price as the SmartCarb SC2 at $699 USD.

I’ve got a 22 sherco 300 with an SC2, and it runs great once I found the sweet spot. The only issue I’ve had was that I was under the impression that the baseline clicker setting was pretty close to what the sweet spot would be. Mine wasn’t even in the ballpark. Baseline was 75 clicks, and the sweet spot is 115. At first I was concerned that something was wrong with my carb because I had to lean it out so much. I now know 3 other people with Sherco’s and one with a Beta with SC2’s and we’re all 35 to 50 clicks leaner than baseline. Would have saved myself a lot of anxiety and head scratching if I had known that the baseline setting could be so far off.

@@michaelcaddell8520Baseline settings necessarily reflect the most common applications using commercially available gasoline fuels. SmartCarb offers a wide range of clicker adjustments to cover the many unforeseen variables across a worldwide consumer base. Pump fuels and their composition, which are based on regulated vehicle emissions are the biggest variable. Additionally in most geographic regions, commercial motor fuel refineries change the molecular weight and composition twice every year based on seasonal changes. To minimize evaporative losses in the summer when temperatures are higher, pump fuels are refined with a heavier molecular weight (specific gravity). In the winter, when evaporative losses are lessened, pump fuels have a lighter specific gravity for easier cold starting and faster engine warmup. 110 LL has a lighter specific gravity than winter blend pump fuels , as such it "lifts" easier, so an initially leaner clicker setting would be expected, compared to a heavier pump fuel that lifts slower and needs a richer setting. Each click position equal .0012" of metering rod movement. 30 clicks is less than one clip position change on a conventional Keihin/Mikuni needle. Seems like a lot, actually it's a very small amount of change.

The first generation XTNG carburetor was a nearly identical clone of the Lectron H Series, right down to the metering rod thread pitch. In fact the rods were interchangeable between the two and XTNG would direct customers to purchase Lectron metering rods. Imagine how Lectron might feel about that. Not to mention the venting check-valve design and copyright theft of SmartCarb Fuel Systems' marketing and user manual graphics and text. The second generation XTNG takes a step backward toward more fuel circuits and greater tuning complexity. That it may give an improvement over the Lectron's bottom end response is secondary both to the fact that there is now a Chinese entrant to the market blatantly copying American designed/manufactured fuel system technologies and to the fact that there is a market solution already available in the SmartCarb SC2 as PNW Enduro demonstrates in this video.

SA isn't the USA. 36 clicks leaner is a bit more than we'd normally see, and Justin would be, and actually was after feedback, better off with a richer setting with a slightly higher idle setting. If it helps wrap your head around just how fine the adjustment is, consider this: 30 clicks moves the metering rod the same distance as a single clip position change moves the needle in the stock carb. It's .0012 inches per click. 6X the adjustment resolution of the rod position as the H-Series Lectron and 3X the resolution of the new Billetrons.

By that logic the Billetron would pull harder down low, but it doesn't. Lectron calls it a 38 but any Billetron owner with 5 minutes on their hands, a telescoping gauge, and a pair of calipers can clearly see that they are 34mm carbs as measured at their narrowest cross-section which is how carburetors are, and have always been, measured. That may be why they opt not to include "mm" in their nomenclature. Even so the bottom end pull difference isn't due to the carb size, but how well each fuel system maintains signal at the metering rod (fuel pick-up and atomization). Part of what makes the SmartCarb stronger is it's variable throttle rate venturi shape. Unlike the round-bore Billetron and it's too-sudden throttle rate off idle, among other factors, the SC2 slows the throttle rate slightly, maintaining a stronger signal at the rod and therefore better performance. That's why Greg here is able to tractor through in a higher gear up those hills using the SC2.

It’s not just a little different the Lectron was garbage at 0-1/4 throttle. It also measures 34mm not the 38 they claim, or so I’m told.

I just got my new sc2 and installed it. Won't idle seem rich. But says not to adjust it till after 1 hour riding. I'm guessing idle adjustment is ok.do you know witch meter rod you have ? Mine is 07 I'm in Washington as well

It will be rich to start, I'm 30 clicks leaner than the baseline setting right now. As you lean it out the idle will also improve. I have the AQ-11 rod.

I’ve ran both carbs on my bike, same pipe, same results. The purpose of the video was to compare them back to back.

A larger carb can hurt torque numbers. May increase hp but….

The 38mm Lectron is actually 34mm if you measure it.

It’s the same model bike. Can’t get a closer comparison.

I think this comparation r not true.. u must be campare on 38 lectron & 38 lectron too.. not 38 compare with 36.. 36 must be more respond from 38.. it's is because 38 lag more then 36..

Already mentioned in other comments if you measure the Lectron properly it’s actually 34mm not 38. Either way, this comparison is the best carb offered from each manufacturer for this application.

Your mix is off

No, it’s not.

not happy with Lectron Carbs. I just bought a $900+ carb off them and they just came out with a new slide for the carb I bought Now they want another $125+ for it ....pissed !!!!!!!!!!!!!!!!

I've got a H-Series Lectron on my 17 300 XCW and its mostly pretty good.. I just can't clean up off idle response totally.. Getting very interested in trying out an SC2 this summer.

If you’re not getting good power from throttle to mid range then you are just still pretty rich just leaning it out a little bit more and that should help out a lot
