This is THE BEST video out there for how to tune this carb. I like how he even tunes his bike the wrong way so you can hear what it will sound like. Thank you, BeRad!
the clips in the end - showing the exact symptoms of each setting are great reference. this is one of those videos you find yourself coming back to for continuous guidance! GG
Brad makes some of the best organized how-to videos I've seen. Excellent camera work and clear, concise directions without any useless content. I'll be grabbing a Lectron from him soon.
This is the best tuning video of the Lectron tuning I have seen ever. Great job B-Rad. I have 2 on my banshee & when I put the t5 pipes on it gave me a fit looking for the sweet spot. Thanks for your thorough video. God Speed.
I have a 2018 yz250x with apex head, FMF. Just added the lectron. Enjoying it so far. This video was very helpful. Being able to hear the bike, the sputtering and different characteristics of lean and rich. Thanks again.
I installed a Billetron 38 in my Husky TE250 earlier this week.... I haven't been able to take it out for a trail ride yet. But for a bike that was never easy to cold start, after the Billetron was in it fired right up and idled perfectly. 👍Throttle response was also quick and crisp. Weather is going to be cold and crappy this weekend but I'm still getting out for a ride with this new Lectron.
Brad. This will soon be the most watched “how to tune a two stroke” video on TH-cam. Lectron or not. Your examples of what a bike sounds and acts like when too rich/lean are great for people who may not have much experience. Kudos, man. Also, what silencer are you running on that 125X? I feel like the TC2 really strips the power and responsiveness away compared to running the shorty. Makes it act like it’s running way rich.
Thanks Scott! I was considering doing a video more about how carbs work in general (comparing standard to metering rod) and then going more in depth with tuning like I did at the end here. Really just wanted a baseline to help customers get set up. That’d be sweet if the video blows up though!
Fantastic guide. The colored text shown at the last quarter of the video with the symptoms helped me a bunch when configuring my 2017 YZ125 stock Mikuni! Mine ran terrible and sucked with mininal throttle input, riding at low speeds had me fighting my throttle and clutch. I use 32:1, and have not have issues with it, just the jetting.
excellent video, nice clear instructions and good how-to, love the end of the video, a picture is worth 1000 words, but this video is worth 10,000! Going to pull the trigger on one for the RM!
Great video. It should also be noted that there are many items inside the engine that can affect jetting/how your bike runs like crank seals and air leaks.
It’s just awesome to see a visual to get a real idea of how too rich or lean looks and sounds instead of just showing people spark plug colors. Yes any air leak can lead you down a rabbit hole. Great video!
Thank you for video. I've been trying to tune this bike. And the sound alone of how it should sound compared to running rich or lean helps a lot. I love you
Great and simple video on tuning, love the demonstration of lean, rich and a perfect running engine. My H series is tuned pretty well but I'm looking to fine tune it even better.
Yeah I’ve yet to see any good info for people regarding what actually is rich or lean. It’s not super in depth but hopefully it at least helps people diagnose the obvious signs.
Your video is very helpful! I had my Lectron H series tuned great from the factory. I'm definitely having to use your video to get my Billetron tuned right. Mine seems to be rich. Thank you for the great content!
Great Video, correct on all points. Too lean can also cause difficult starting, dry plug, just went thru this issue with my Billetron38. Idle should be 4 to 5 turns out, in less than 4 or hard starting adjust rod richer. And make your determination riding, under load, on the stand isn't an adequate evaluation, ....just like BRad did in this video
Good job on the video. Something that you forgot to point out is that the engine will naturally run leaner at a given throttle setting when it has a higher load, so you should avoid tuning at low load conditions.
Merry Christmas BeRAD I just found your videos 5 days ago and having a blast watching them I just picked up a new factory Demo YZ250X and can’t wait to rip up the trails again after taking a ten year break. Hope to see some new riding videos soon.
Just the video I needed amazing work mate I’ve been trying to find a good video like this to tune my lectron I can definitely say it is running very rich after watching your very detailed video definitely will subscribe
Can too rich cause bogging as well? Oh my stock carb I would only have to keep the choke on for 30 seconds, and could ride the bike without any weirdness. With my Lectron if I turn the choke off after even a minute it will bog and die constantly. If I keep the choke on and rev it a lot and it gets warm. It runs fine. Smokes more than on my stock carb but feels like it has more power.
I just got a YZ250 with a Lectron and it was constantly foiling plugs. I went a half turn lean and then it seemed to run ridiculously warm. I was also really skipping the clutch to get out of sand. So I went 1/4 turn richer. Hopefully I finally got it.
My kx250 is very close but needs a little adjustment. It fouls a plug about once a year and maybe sputters from time to time. I definitely have to clear it out when in low rpm, especially after a long downhill decend. Now i just rip the throttle in neutral on my way down. Looks to me like its rich. Which also makes sense because im at 4000+ ft on the stock jetting. I dont have a Lectron. Thinking about getting one, but at the very least jetting my carb properly.
Great info. It helped me get my carb running awesome. Can you help on the cold start? I pull the choke, but have a difficult time getting it atarted. Once started, it runs awesome
Stellar video. I looked and high and low for a video like this. I have a SC 2 on my Beta 300 and could never find a video that actually showed what the different states of tune sounded/looked like. 🤘🤘
Great! I’ll try to do a more in depth one strictly about the signs. This is just surface level but at least a decent baseline for someone who doesn’t know. So many variables!
@@BeRAD YES BERAD...More indepth carb tuning vids! I sometimes have an off idle bog with my yz250X and hanging idle..Ran worse with APEX XC Head! Tried JD JEtting too ...better with sotck jets and stock head!! May buy Billetron though, looks like an AMAZING CARB for the WOODS!!!
Might be a stupid question but im new to two strokes. I have a Lectron carb on my TC 250 and I have noticed there is too much fuel entering the motor when I turn the gas on, this is causing the spark plug to become wet with gas. 1. Do I need to adjust the tension cable for the throttle adjust the entering rod to stop excess fuel going into the motor? 2. Doe the metering rod require that black tool you are using to adjust the metering rod? Thanks!
Is there any place that sells just to bowl? Just got a yz125 and the bowl is cracked!! Looks like last owner overtightened the bowl screws leaks a lil gas!!!
Hi Berad, Is it possible for you to show us how to clean the billetron sometime? Can't find anything on the internet on how to do it properly and dismantle in the right order. Because it's a different style of design i wouldn't be so sure on how to do it🙂
Hi I have just got a billetron pro 38 for my ktm 150 it’s idle lovely and rips hauls ass over half a throttle but how can I get rid of spluttering in 1 2nd 3rd gear when transitioning into powerband it’s horrible any help. Would be reallly appreciated thanks
300xc with h series, just started bogging off and on after it ran flawlessly for 20-30 hours. Only thing I have ever done to the carb was 1/2 turn richer after first ride. Plug looks light brown on tip but black on the threads.
Got a 250sx here, after 18hours it started then stalled and wouldn't want to go. Spark was black and from the feeling of the bike compared to his video I'm sure it is a bit on the rich side. Got a new spark in and started on the first kick.
Hi BeRad, just got an lectron for my cr250. Having some trouble getting it perfectly dialed, like how yours runs in the video. Running 32:1. Can’t quite seem to get the idle consistent, starts first kick without choke and seems to be clean throughout the rev range. But idle seems lean, will hang for a sec then drop then return to normal. but the plug is golden brown. Any suggestions? Lean or rich?
When I first got my Pro I messed with the idle screw and forgot how much I turned it out. Is there a way to reset it? Like turn all the way in and two turns out?
In your next video like this can you show pictures of the spark plug coinciding with the tuned condition. I ask this because I fear I am running too lean and may cause damage
Great question! I can’t recall but it was maybe 2 full turns each direction. I think I pulled the choke for the rich condition just so the audio and visual of smoke would pick up better for camera. The lighting wasn’t showing the smoke well that time of day. But sound is the same.
Just found this video after picking up a 2018 yz250x with the older style lectron, spark plug is a perfect tan after some full throttle chop tests but smokes abit after start up and bogs down when I whack open the throttle from idle just like in your lean demonstration, new to two strokes and was thinking it’s too rich but maybe I’m looking at too lean ? Thanks for the video!
Must be too lean if that’s the case! Smoke is expected. It’s a 2 stroke burning oil and fuel! No smoke woukd be a concern. Tune based off of how the motor runs/feels/sounds. Smoke is a poor indicator. I just threw it in there as a last resort test hah
Quick question for anyone with a Lectron, will your bowl run dry when you shut off the gas? Mine always has some left. This carb has been a major pain in the ass compared to a stock carb on my YZ250…
The stock carburetors on both my YZ125 and TTR125 will leave some in the bowl after stopping the engine and turning off the gas. I don't think either stock or Lectron would empty the bowl when the gas is off, unless you empty it by running the engine.
Is that a 36 or 38 carb? And why? Thank you for being the only youtuber reviewing an aftermarket carb on a 125. I've been struggling with my 06 cr125. Besides a full rebuild, I've been wanting a smart carb for over a year now. . .
Hey I don’t have a lectron, but I have a 2006 ktm 125 sx and I’m having a lot of issues with jetting . I’m having a lot of rich symptoms , but also some lean symptoms . It honestly feels like a mess. Is there anywhere I can dm you, like Instagram to show you some videos of the bike , to help determine what it needs?
One thing on my 04 rm250 lectron h series I noticed the idle will always drop low to the point it wants to stall, even if it’s set too lean. Also it won’t bog when wacking the throttle while putting around in second gear to wide open, but it will bog when giving it lots of throttle in mid air? I found that really weird and really sketchy. So I richened it and now it doesn’t do that, but it won’t hold and idle hardly at all.
I installed a lectron H series on my YZ125 with a Athena kit 144 boyensen rad valves and full fmf exhaust and she’s bogging I need to rich her up or lean ?
If you’re 2 full turns richer on the rod you very likely have an air leak somewhere. That’s a very large amount of fuel compared to what it should be. Unless you rod got set weird from factory. The PJ is set stock at about 1 turn out.
@@BeRAD should I turn it back ? Leaner ? When I first installed it ? When it was how it was the throttle was super easy to rev up it seem like it skip rpm’s and went straight up high in stead of like climbing ? Would I be losing power if there’s an air leak ? Or what’s a big notice I have a air leak ? Please get back with me
Also can it be the idle why the bike would died once I put it into first with out like reving it up giving it a lil bit of gas ? Earlier today I turn it half turn leaner and tbh it felt good to me but idk , where should I set the idle screw ? Bc idk know how high I should have it or low
Well my day going down hill , I warmed up the bike & went riding after turning it a bit lean , the bike as I was riding ended up just revving high even when I turn it off and start it back up it starts revving
I bought a lectron carb last year for a yz250 with esr325 kit. Cant ever seem to get it right. I adjust it to lean and it starts decent. Then it runs lean like in the video. I adjust it a 1/4 turn rich and it runs great but a pain to start. I dont know what to do hopefully you have some advice. On 10-20 hours on engine and has good compression. Was a full rebuild and checked crank seal. Everything is check 3 to 4 times over. Just a pain to start... have to slow kick it a 7 times and hopefully a hard kick or 2 will start it. I put the old carb on and starts right up but that has a crack on the housing
Any recommendations for tuning a 2022 YZ125X Mikuni carb? Mid and top end seem good, low and idle always seem a little off and boggy, and load up after 30 seconds or so of idling.
Nice video! Very informative, maybe you could give me a few tips to help me with my new billetron carb. So the carb was meant for my yz125 and I decided to put it on my KTM 125sx 2015, and not matter what I do I can't get it to idle, no one seams to know what the rod measurement is for My KTM. Do you know what the measurements are for my other bike? Or what are some tips what I should try? I'd be happy for a little help, it seems to be endless right now to find the sweet spot! In the lower RPM it doest throttle well at all, sounds like it's too lean but smokes like nothing else I have tried to make it more lean and the sparkplug was pretty white. Maybe I'm over jumping that good point, honestly at this point I have adjusted it too much to know which way I should go now. THANK YOU :)
I have a question my yz runs good doesn’t bog can idle all day with no issues however after a while of riding there is a little bit of oil around the plug on the head bike doesn’t smoke too crazg would you recommend going a little leaner on air fuel screw or adjust the other thing on the inside of the carb as I do have a lectron carb installed and I am running 32:1
Just got a billetron. Cleaned up the blubber and spooge on the bottom end with a 1/4 turn leaner. Now, it’s flat / almost boggy in middle when hard on the gas. Question, do you always have to adjust the powerjet when you make meter rod adjustments? What would you do if you were me?
You just talked me out of getting a smartcarb!! You saved me some money!! Se my issue is i live ay 5000 fet in the mtns and will ride anywhere from 4 to 55 hundred feet! And the track we have to ride at is at 800ft.. how will that workout for me..?.
In my experience, I make no adjustments whatsoever between sea level and 7000ft, if I’m going to be between 7k and 11k feet I’ll lean it out 1/4 turn on the metering rod. That’s it. Takes 2 minutes 😊
do you have a base setting where I can start. living in southern pa. I cant get it right and ready to throw in trash and get a pwk 38. I've tuned carbs for years with no issue but cant figure this thing out. 2018 ktm 300
Power jet should be around 1 turn out as a base setting. Get ahold of lectron, their support is quite great 😊. Or email me if that fails. Email in description. Maybe there is something else going on that is causing it to be difficult to tune in.
Hey Brad, I just bought a 85SX and since it's my 1st 2t I'm not familiar with 2t sound, your video is really helping. However, I have a lot of difficulty to hit the sweet spot with tuning my Keihin. I know it's not a Lectron but I'd like to figure it out before buying something else. I have a lot of smoke at idle and while riding, and most of all I have spooge (a lot) coming out of the exhaust. I already lean it a bit with the pilot jet and the needle but I don't want to lean it too much. The bike was brand new when I got it and it has about 15h now. Is there something you would suggest me?
This is THE BEST video out there for how to tune this carb. I like how he even tunes his bike the wrong way so you can hear what it will sound like. Thank you, BeRad!
the clips in the end - showing the exact symptoms of each setting are great reference.
this is one of those videos you find yourself coming back to for continuous guidance! GG
Glad it was helpful! No sense in showing someone how to adjust the carb if they don’t know which direction to go in 😊
Brad makes some of the best organized how-to videos I've seen. Excellent camera work and clear, concise directions without any useless content. I'll be grabbing a Lectron from him soon.
This is the best tuning video of the Lectron tuning I have seen ever. Great job B-Rad. I have 2 on my banshee & when I put the t5 pipes on it gave me a fit looking for the sweet spot. Thanks for your thorough video. God Speed.

all you need now is vforce 3 reeds, higher comp piston and itll be a true monster
You’ve saved me probably 30 minutes of reading, rereading, and hair pulling. Thanks!

I’m running the TC2. Haven’t ran a shorty yet but spark arrestor is needed a lot of places I ride. I also like my bikes to be kinda quiet.
Well done...
This right here.
This is the best instructional tuning video I've ever seen. Thank You!
Fantastic guide. The colored text shown at the last quarter of the video with the symptoms helped me a bunch when configuring my 2017 YZ125 stock Mikuni! Mine ran terrible and sucked with mininal throttle input, riding at low speeds had me fighting my throttle and clutch. I use 32:1, and have not have issues with it, just the jetting.
Dude I got the 38 for ktm 250sx with big bore kit 295. Been challenging turning. This will get me started, much appreciated. 👍
This is the best carb tuning video I've ever seen.
Dude what a great video! The second half is great for any carb tuning!
Thank you for the video, this is exactly what I was looking for. Finally I got my YZ dallied in to sound good and work good as your machine.
excellent video, nice clear instructions and good how-to, love the end of the video, a picture is worth 1000 words, but this video is worth 10,000! Going to pull the trigger on one for the RM!

Too lean can also cause difficult starting, dry plug, just went thru this issue with my Billetron38.
Idle should be 4 to 5 turns out, in less than 4 or hard starting adjust rod richer.
And make your determination riding, under load, on the stand isn't an adequate evaluation, ....just like BRad did in this video
Thanks. This is so much better than all the other video's.
Glad you think so! Definitely not much out there for actually showing what the different signs are if rich/lean.
Best live example yet thank you. How do you know of the main is too lean tho
Good job on the video. Something that you forgot to point out is that the engine will naturally run leaner at a given throttle setting when it has a higher load, so you should avoid tuning at low load conditions.
you made such a good tutorial like no one else on this earth!

4:56 what about oil starving the engine with it being a two stroke ??
LMFAO with it being a two stroke lol. The oil is blended in the gas
Just the video I needed amazing work mate I’ve been trying to find a good video like this to tune my lectron I can definitely say it is running very rich after watching your very detailed video definitely will subscribe
I really enjoyed the too lean and too rich examples. Pretty awesome you could show those examples in the field with that easy tuning. wow!
You rock I just adjusted my h series and holt crap it flies especially paired with the ESR 325
Can too rich cause bogging as well? Oh my stock carb I would only have to keep the choke on for 30 seconds, and could ride the bike without any weirdness.
With my Lectron if I turn the choke off after even a minute it will bog and die constantly. If I keep the choke on and rev it a lot and it gets warm. It runs fine. Smokes more than on my stock carb but feels like it has more power.

Finaly one very interesting video on rich and lean sounds like engine.

Might be a stupid question but im new to two strokes.
I have a Lectron carb on my TC 250 and I have noticed there is too much fuel entering the motor when I turn the gas on, this is causing the spark plug to become wet with gas.
1. Do I need to adjust the tension cable for the throttle adjust the entering rod to stop excess fuel going into the motor?
2. Doe the metering rod require that black tool you are using to adjust the metering rod?
Thanks!
I'm convinced you'll be new Jarvis one day. Your control of the bike is amazing man.
A viewer since the old times of the yz450 supermoto 😁
Haha long way to go to even touch Jarvis! But thank you 😊
Thank you you doing better than lectron them self big help about to fix my yz thank you for your help your amazing make more videos like this please
Is there any place that sells just to bowl? Just got a yz125 and the bowl is cracked!! Looks like last owner overtightened the bowl screws leaks a lil gas!!!
I had my 125 running just like yours with a new Lectron and I ended up cooking the piston ring after 3 hours. Any advice?
Fantastic video! Well done!
Question if you forget the number of turns are you out of luck or do you is there a way to get back to an accurate count?
Hopefully this works because for me to get in the power band I need to pin it
Hi Berad,
Is it possible for you to show us how to clean the billetron sometime? Can't find anything on the internet on how to do it properly and dismantle in the right order. Because it's a different style of design i wouldn't be so sure on how to do it🙂
Excellent video and information. What's the RPM at when you are idling?
I bought my first yz 125 it’s a 97 and I plan on turning it into a woods bike.
So... I guess I've been living under a rock, but what type of carburetor is that, and how is it different from a " regular " carburetor ??
How much did u turn the rod on the video to show from rich to just right? Mine is slightly to rich. Just wondering how much to lean it out abit
best video i have seen to date thank you
What would you recommend if lectron will not start cold while on choke? Only starts with choke off and at full throttle. Once warm starts 1st kick.
Hi I have just got a billetron pro 38 for my ktm 150 it’s idle lovely and rips hauls ass over half a throttle but how can I get rid of spluttering in 1 2nd 3rd gear when transitioning into powerband it’s horrible any help. Would be reallly appreciated thanks

When I first got my Pro I messed with the idle screw and forgot how much I turned it out. Is there a way to reset it? Like turn all the way in and two turns out?
Anyway we could see what ur plug looks like?
In your next video like this can you show pictures of the spark plug coinciding with the tuned condition. I ask this because I fear I am running too lean and may cause damage
I just installed a billetron on a 2000 yz250. It won’t start. Not sure where to start
Where do I get a lectron carb and skid plate for a 2023 yz 125x
I’m wondering how many times you had to turn the metering rod to get it to run so rich/lean?
Great question! I can’t recall but it was maybe 2 full turns each direction. I think I pulled the choke for the rich condition just so the audio and visual of smoke would pick up better for camera. The lighting wasn’t showing the smoke well that time of day. But sound is the same.
If it was to rich would it cause a hanging idle and bog after idle if you hold it wide open.?
Usually that’s a sign of too lean. But could also be worn or broken reeds or an air leak…causing a lean condition.
Cool vid, I can hardly wait to jet my buddy's bike too lean when he's not looking.
🤣🤣🤣
So that you can bog he's bike for the holeshot 😊
Can I ask what is the function of the RAD Valve?
Awesome video, thanks for sharing your knowledge 👍
Excellent how-to video on the new Billetron! I'll be ordering one, along w/ an XC dome, here very, very soon. :)
Thanks! Sounds great 😊
I have apex head mx dome an lectron carb this bike rips yz125 2003 so fast
Just found this video after picking up a 2018 yz250x with the older style lectron, spark plug is a perfect tan after some full throttle chop tests but smokes abit after start up and bogs down when I whack open the throttle from idle just like in your lean demonstration, new to two strokes and was thinking it’s too rich but maybe I’m looking at too lean ?
Thanks for the video!
Must be too lean if that’s the case! Smoke is expected. It’s a 2 stroke burning oil and fuel! No smoke woukd be a concern. Tune based off of how the motor runs/feels/sounds. Smoke is a poor indicator. I just threw it in there as a last resort test hah
Quick question for anyone with a Lectron, will your bowl run dry when you shut off the gas?
Mine always has some left. This carb has been a major pain in the ass compared to a stock carb on my YZ250…
The stock carburetors on both my YZ125 and TTR125 will leave some in the bowl after stopping the engine and turning off the gas. I don't think either stock or Lectron would empty the bowl when the gas is off, unless you empty it by running the engine.
Is that a 36 or 38 carb? And why?
Thank you for being the only youtuber reviewing an aftermarket carb on a 125. I've been struggling with my 06 cr125. Besides a full rebuild, I've been wanting a smart carb for over a year now. . .
best two stroke real time demo....
Would you recommend an electron carb for a YZ250 street legal dual sport build? With longer than average higher RPM cruising? Richer setting? Thanks
if i dont have the carb adjustment tool can i just use like needle nose pilers
Hey I don’t have a lectron, but I have a 2006 ktm 125 sx and I’m having a lot of issues with jetting . I’m having a lot of rich symptoms , but also some lean symptoms . It honestly feels like a mess. Is there anywhere I can dm you, like Instagram to show you some videos of the bike , to help determine what it needs?
Is it okay if it’s rich ? Since my bike is brand new and I need to ride it slow .. after 1 tank I should play with the carb abit?
One thing on my 04 rm250 lectron h series I noticed the idle will always drop low to the point it wants to stall, even if it’s set too lean. Also it won’t bog when wacking the throttle while putting around in second gear to wide open, but it will bog when giving it lots of throttle in mid air? I found that really weird and really sketchy. So I richened it and now it doesn’t do that, but it won’t hold and idle hardly at all.
Is it the same for 4 strokes
I installed a lectron H series on my YZ125 with a Athena kit 144 boyensen rad valves and full fmf exhaust and she’s bogging I need to rich her up or lean ?
Hey how far out did you have your power jet set on your H series with the YZ 250. Still not sure how to tune that part of the carb…
For the power screw jet where should it be like regular if you get me ? I run 32:1 927 , w the same lectron , 2 full turns richer on the metering rod
If you’re 2 full turns richer on the rod you very likely have an air leak somewhere. That’s a very large amount of fuel compared to what it should be. Unless you rod got set weird from factory. The PJ is set stock at about 1 turn out.
@@BeRAD should I turn it back ? Leaner ? When I first installed it ? When it was how it was the throttle was super easy to rev up it seem like it skip rpm’s and went straight up high in stead of like climbing ? Would I be losing power if there’s an air leak ? Or what’s a big notice I have a air leak ? Please get back with me
Also can it be the idle why the bike would died once I put it into first with out like reving it up giving it a lil bit of gas ? Earlier today I turn it half turn leaner and tbh it felt good to me but idk , where should I set the idle screw ? Bc idk know how high I should have it or low
I also never touched the power jet screw which was should I turn it leaner or richer or how would Ik what my bike needs to be ?
Well my day going down hill , I warmed up the bike & went riding after turning it a bit lean , the bike as I was riding ended up just revving high even when I turn it off and start it back up it starts revving
I bought a lectron carb last year for a yz250 with esr325 kit. Cant ever seem to get it right. I adjust it to lean and it starts decent. Then it runs lean like in the video. I adjust it a 1/4 turn rich and it runs great but a pain to start. I dont know what to do hopefully you have some advice. On 10-20 hours on engine and has good compression. Was a full rebuild and checked crank seal. Everything is check 3 to 4 times over. Just a pain to start... have to slow kick it a 7 times and hopefully a hard kick or 2 will start it. I put the old carb on and starts right up but that has a crack on the housing
Making the carb richer 1/4 turn should only make it easier to start. Be sure you’re using the choke in any case to cold start!
Hey bro why is my bike running fine but when i let off the throttle it Holds the revs for like 10 secs
Any recommendations for tuning a 2022 YZ125X Mikuni carb? Mid and top end seem good, low and idle always seem a little off and boggy, and load up after 30 seconds or so of idling.
What are you idling at
When its to lean the spark plug is white right?
Nice video! Very informative, maybe you could give me a few tips to help me with my new billetron carb.
So the carb was meant for my yz125 and I decided to put it on my KTM 125sx 2015, and not matter what I do I can't get it to idle, no one seams to know what the rod measurement is for My KTM. Do you know what the measurements are for my other bike? Or what are some tips what I should try? I'd be happy for a little help, it seems to be endless right now to find the sweet spot! In the lower RPM it doest throttle well at all, sounds like it's too lean but smokes like nothing else I have tried to make it more lean and the sparkplug was pretty white. Maybe I'm over jumping that good point, honestly at this point I have adjusted it too much to know which way I should go now. THANK YOU :)
I have a question my yz runs good doesn’t bog can idle all day with no issues however after a while of riding there is a little bit of oil around the plug on the head bike doesn’t smoke too crazg would you recommend going a little leaner on air fuel screw or adjust the other thing on the inside of the carb as I do have a lectron carb installed and I am running 32:1
Just got a billetron. Cleaned up the blubber and spooge on the bottom end with a 1/4 turn leaner. Now, it’s flat / almost boggy in middle when hard on the gas. Question, do you always have to adjust the powerjet when you make meter rod adjustments? What would you do if you were me?
You just talked me out of getting a smartcarb!! You saved me some money!! Se my issue is i live ay 5000 fet in the mtns and will ride anywhere from 4 to 55 hundred feet! And the track we have to ride at is at 800ft.. how will that workout for me..?.
In my experience, I make no adjustments whatsoever between sea level and 7000ft, if I’m going to be between 7k and 11k feet I’ll lean it out 1/4 turn on the metering rod. That’s it. Takes 2 minutes 😊
do you have a base setting where I can start. living in southern pa. I cant get it right and ready to throw in trash and get a pwk 38. I've tuned carbs for years with no issue but cant figure this thing out. 2018 ktm 300
mainly asking about the top screw. not sure if im.chasing my tail with rod cause that upper screw is way off?
Power jet should be around 1 turn out as a base setting. Get ahold of lectron, their support is quite great 😊. Or email me if that fails. Email in description. Maybe there is something else going on that is causing it to be difficult to tune in.
@@BeRAD thanks. il start there.
Hey Brad, I just bought a 85SX and since it's my 1st 2t I'm not familiar with 2t sound, your video is really helping. However, I have a lot of difficulty to hit the sweet spot with tuning my Keihin. I know it's not a Lectron but I'd like to figure it out before buying something else. I have a lot of smoke at idle and while riding, and most of all I have spooge (a lot) coming out of the exhaust. I already lean it a bit with the pilot jet and the needle but I don't want to lean it too much. The bike was brand new when I got it and it has about 15h now. Is there something you would suggest me?
I will be ordering the first week in march!!!
