Ive been running the 48mm lectron on my fxr with an s&s 124 for about 4 years. Took Kevin a few trys at finding a good grind on the metering rod to get dialed in for a big motor but after a few it was ok. I run an air fuel meter so i was able to fine tune on the road. Dont have to touch it much. The idle circuit is the best ive ever heard. I have a few videos on my youtube if you want to hear it

[@greasesgarage]

I will definitely check those out thanks for sharing brotha

[@Lochlann13]

Gotta love the custom made VOES vacuum line plug! You had mentioned once in a previous video that I commented on to hit you with any topics we'd like to see covered. Personally, I'd love to see a breakdown of the VOES system: how exactly it works, how to tune it, how to remove it, etc. Another topic I think would be fascinating is the modifications required to convert an EVO motor to a kicker system.

[@Rif_Leman]

My '84 EVO came from the factory with a kicker and electric starter.

[@greasesgarage]

Hahah I almost forgot about that “temporary” fix that’s been on there almost two years now! As for the VOES, I can definitely tell you how to remove it, and I will add that (with the kicker part too) to the video topic list. As far as tuning the voes, I need to go to school before I can put that video out haha, I will do some research on it though and see if I can’t sum it up

[@djd34d14]

I'm guessing the simple answer to removing VOES is points eh? 😅

[@Lochlann13]

@@djd34d14 If you have an electronic ignition, technically you can disconnect and plug the VOES. My confusion is whether to ground the VOES wire, or simply cap it. Then there's the question of what to change on the ignition module switches... So yeah, converting to points may just be simpler lol

[@Lanesplitter]

I put a Dyna S on my Evo, plugged the VOES vacuum port on the carb (HSR42) and used a good quality (stainless steel) mechanical advance - she kicks much easier and runs like a stabbed rat! @@Lochlann13

[@garyhopkins6337]

I saw a vid from Shade Tree where he installed a brand new Lectron on his HD and it worked a treat. These carbs seem to be old teck but like an old amal or Mikuni you do have a lot of adjustment with needles and slides, it just takes a bit of stuffing around like carbs sometimes do.

Just carb converted my '00 Road King. Save yourself a headache. I used the sifting 40 mm carb. All stock and aftermarket parts for the cv carb Harley uses works with it. It fired right up and haven't done any adjustments yet but it runs up and down the road beautifully. You also have to change out the ignition module

[@robertking5701]

@shameless5868 i was curious about the module. I've got an 03 RK. Appreciate the advise.

Would be nice to see a SU or Mikuni HSR42 set-up - both reputedly kick-friendly carbs

[@chipmartin7608]

Can't wait to see part 2. I've been considering one of these but the jury's still out until I can get some more information. Like you said, there's not a whole lot of reviews out there. BTW, that's a really cool jacket you have on, is it an Aero? You make very helpful and informative videos; keep 'em coming!

[@greasesgarage]

Yes it’s a tricky one to figure out, I’ll need another week or two to get part 2 together. The jacket is made by Schott, imo the best USA manufacturer of motorcycle jackets. This was a d pocket model they produced for legendary USA back in 2015 with horsehide leather, I hope to have it for the rest of my life

[@chipmartin7608]

@greasesgarage Very nice! I have a 118 in cowhide and a 618 in horsehide and will probably get a 613 in steerhide soon. I was also looking at a J-106 Aero which is a D-pocket style, because three Schotts is enough, I think. Thanks for the replies!

[@greasesgarage]

@@chipmartin7608ayy a fellow jacket enthusiast, that’s awesome! I had both of those before this one and kept buying and selling only ever keeping one at a time. Had a 613 for a bit there too. But once I got into bikes more deeply I went for one with a little looser fit to allow some layers. Schotts horsehide on this model is fantastic, I believe i only paid $400 for it back too, on sale at legendary. Maybe I’ll do a video on riding gear and get some better shots of this and some of the other gear that’s saved my skin

[@greasesgarage]

[@djd34d14]

Having just made some changes on mine and having to disassemble the carb every time it doesnt do what i expected it to on a certain jet combo, this sounds like a dream. But hearing that one idle like that doesnt sound quite like a dream. Looking forward to part 2 where you wake me up or put a lectron on my wishlist. #cvforme #exceptforwhenitactuallyneedstuning

[@greasesgarage]

Yea man I can’t imagine having to disassemble the whole thing every time! But hey the super E is a good in between option man. Can pop the jets out in no time and dialing it in is a little more straightforward than these lectrons

[@frankjoosten3501]

Mine works excellent on my rebuild shovel,bought it straight from lectron.

[@GidDree]

No problems so far? Do you ever need to use the choke?

[@frankjoosten3501]

No problemen,it runs perfect. No choke needed

[@ArboRTT]

Following because I'm also working with a Lectron HD 400 right now and there is nothing out there about these in depth, aside from a handful of old videos from Lectron. Mine was pouring gas, also thought it was a stuck float... took the bowl off, and it was fine. They recommend spraying WD-40 in the fuel inlet directly, followed by low PSI compressed air through the fuel line (plugged back into the inlet) to clean the fuel intake portion. Mine has stopped dumping gas since, but I'm waiting on the meter rod tool in the mail still to dive into the fine tuning

[@greasesgarage]

I must say, I was intrigued about the not having the buy jets portion of these carbs but if I have to buy metering rods and metering rod tools I feel like it’s the same devil, still more pieces to buy. I will see if I can’t get by with just tuning the metering rod I have. Hope you get a resolution as well man

[@ArboRTT]

I believe you can adjust it with your fingers, the tool seems to make the job easier and a little more precise. It was $20 from them directly. I want to keep the carb and learn it. I hope I'm headed in the right direction!

[@507cycleshop]

if you are having high idle and turning the ISS in all the way with no change, chances are that you're running on the metering rod and not on the idle circuit. There is a factory spec for the length of the metering rod that might need to be reset for your specific bike.

[@greasesgarage]

This is good to know! Going to check on this and put that process in the part 2 video on tuning. Sounds like I will have plenty to cover

[@GidDree]

It seemed to me the choke was pulled, that's why all the smoke and no idle slide adjustability???🤔

[@BrianMikasa]

You should do the Tektall hsr42 clone. I just put one on my Evo dyna and it seems really damn close to the real thing.

[@greasesgarage]

Great job explaining the installation. I think I will stick with my stock carb as it works great. Not impressed with this new carb.

How did you get on with part 2 great video, I’ve got a standard 97 fatboy, love it.

[@greasesgarage]

I never did get around to part 2. Half because I needed it running for another video and the other half due to lack of interest. I can’t recommend it personally but some people swear by them. I prefer my super E

[@salsandoval4069]

How do I adjust the rod from sticking

[@haroldgoeckeritz1671]

what tube are you using for the throttle cable? I've been running one on a 98 Dyna. I've had allot of issues with the throttle sticking, either the slide isn't completely closing from airflow or going to a single cable setup. I've also had the same issue with fuel flow, I'll have to try your suggestion. great video. Thanks.

[@greasesgarage]

Throttle cable is from lectron. In watching the video back I don’t think it’s from the throttle cable being too short as one commenter suggested because even when showing the carb without the throttle cable attached that slide stays slightly open at the bottom

[@sarron7620]

Sounds like the Super E is the best option to me

[@greasesgarage]

Haha, it's definitely the one I like the most as of right now. But if I bought direct from Lectron this might have been a more straightforward process. Hard to say for sure.

[@RitzCaraldo]

Can anyone on here recommend a simple fuel injection system for a turbo harley. Or does anyone know how to tune a mikuni for turbo applications?

[@robertvilliard3402]

Does it have a drain screw on the bowl.

[@greasesgarage]

I don’t believe so

[@YerGoodBuddyKeith]

I'm glad i watched this, I'm OCD and that fuel line would have driven me nuts. I just found a bunch of 90 degree fuel line bits that you just measure your tube, cut and bond. You can really tuck that fuel line up and away nice and pretty.

[@Thepeanutgallery666]

Maybe I'm just noticing little stuff that doesn't matter, but it seemed like the mounting surface on your manifold wasn't very clean. There might have been enough on there to cause a vacuum leak. Just throwing it out there. That could also be causing your idle problems.

[@greasesgarage]

It could be. I have since reinstalled the super e on the bike (see my kickstart video) and it runs perfectly so I am inclined to believe it’s something to do with how I’ve got the settings on the lectron

[@galinvayov]

Maybe the throttle cable is a bit short? The throttle slide is held high and is not controlled by the adjustment screw. Otherwise, from what I see, it seems to me that this is a rather primitive carburetor.

[@greasesgarage]

Could be, I will have to check on that

[@mcluvinole9098]

If you have a high idle and the screw doesn’t do anything you need to open up the slide and reinstall it. There’s a process to it. If you look up the PDF installation manual, it’ll specify how. Lectron is horrible with documentation actually. Not your fault. It’s easy to miss. Trust me, I’ve battled running on my FXR. It ain’t plug and play. But it’s a nice carb for what it is

[@greasesgarage]

Thank you for this! I will give that a look, I appreciate the tips 🙏🏼

[@mcluvinole9098]

You basically have to slightly crack the throttle open before you fully torque down the top screws on the slide housing screws. Once torqued release the throttle. Then you’ll notice the adjustment screw doing something to the slide height.

[@GidDree]

​@mcluvinole9098 That makes a lot of sense, like the slide has to sit on the screw right before it can be adjusted up or down, you know simple common sense tricks like you and I know, is what the " YOUNG COMPUTER TUNING GUYS" get lost at..lol....I was thinking at first the choke was pulled, hence the smoke and unadjustable idle🤔

[@benjaminpina6309]

i bought a brand new lectron a few years back fro my sportster. once i got it tuned (PITA) it was fun, the throttle response is wild. it definitely does not make more power than the stock CV, and it definitely does not deliver better MPG like lectron claims. it's been a constant love hate relationship with that carb. lectron hypes their product up a bit too much imo.

[@tattooglisha]

CV carb rules!

[@midas61]

What happened to part 2?....Choke and enrichener are NOT the same thing. A choke restricts air flow which pulls more fuel and an enrichener actually lets in more fuel without restricting air flow..

[@greasesgarage]

We get it, thanks

[@stephengibbs4372]

Maybe the inner cable is too short and holding the slide up?

[@joshghost661]

One of my buddies swears up and down the Mikuni carb is way better than the Lectron. Any thoughts?

[@greasesgarage]

My most honest recommendation is the S&S. For the simple things you do most on a carb. Extended screws available that allow you to adjust it by finger at a light, throttle cable is externally mounted and easy to remove, parts available everywhere because it’s one of the most popular carbs, every cool air cleaner made is always made for S&S…there’s a lot to love.

[@Lochlann13]

As far as I know, you can, as long as they will physically fit the manifold on your Shadow. You'll need a Mikuni 48mm push-in manifold or similar. Lectron sells their carbs by displacement; they have a v-twin carb for motors from 53ci - 100ci, and a carb for motors larger than 100ci.

[@Lochlann13]

@@carlosviedas199 The benefit of the Lectron, in my experience, is the throttle response improvement, a wider, more linear power band, and increased reliability. I've heard that they also slightly increase horsepower, but can't confirm that myself. They do make kits to convert a carbureted motorcycle to a fuel injection system, but they're pretty expensive from what I recall. If you don't want to hire a shop to install it for you, you'd have to know a fair bit about wiring, electronics, and engine tuning to get it running right.

[@brysonwaterfield7861]

The floats stick! And if you leave your bike sitting for more than a month the metering rod will get stuck to where the throttle will not work! When you try to unstick it the metering rod will pull out of the slide housing. On your bike you need to turn the metering rod out one eighth of a turn and turn your fuel in one eighth of a turn and it will idle fine. My hd400 I bought was 1,000.00 Dollars not a cheap investment but once you figure out how to set it you will find your performance of your bike will be a changed animal.

[@greasesgarage]

I’ll try this with the metering rod. I don’t believe the float is stuck though I took the bowl off and moved it around I’d be surprised if it was still stuck

[@bradleyyounger8499]

I have had the CV S&S and mikuni on my Harleys. I had a lectron on a 2 stroke. To me the best one for the Harleys is the S&S. All of them have pluses and minuses but for me the S&S just always works. The CV and mikuni are temperamental and requires rebuild more often. Haven't tried the Lectron on the harley but have thought about it but prefer the simplicity of the super e

[@greasesgarage]

The super E is without a doubt my favorite carb and it’s what I continue to run on my bike

[@lancmac]

The lineage is from the OLD POSA carb from circa 1970.. Then it was cross bread between Amal, Mikuni and POSA.... Not a very good carb as it only works well on one setting. All other throttle positions are a compromise.
