30mm Lectron High Velocity Scooter Carburetor Install & Tuning & Breaking Stuff : TPR 86cc : Part 50
HTML-код
- Опубликовано: 28 июн 2024
- In this video I'll be installing a 30mm High Velocity Lectron carburetor and a larger intake to accommodate it, as well as a new air filter. The entire process is shown in detail with every step of the tuning that I've tried included. Near the end of the video, the scooter starts to have trouble.
Some of the setup process and tuning is not how it should go, but I'm showing you my experience with the process that I used as someone that is not accustomed to flat slide, power jet or metering rod carburetors. Be sure to watch this video all the way through and stay tuned for the next one.

I greatly appreciate your honesty these carburetors are new to me as well, it’s what happens when you’re human we live and learn I’d love to mess with those carbs but when I saw the 700 dollar price tag I almost passed out good luck with the project and I’ll catch you on the next one.

That hour seemed to take about 10 minutes. I love your vids, I always learn from them. Props for not hiding anything either.
I can't believe we are on episode 50 of the TPR build already.
It sure is a learning experience.
Good work with the graphics 👍
Thank you!
Every breakdown and failure is an opportunity to upgrade fo mooo powaaa.. but on the plus side I glad you don't get discouraged and quit. Keep it up
Great vid. Showing all the mistakes is a great lesson for others. One of my favorite sayings is “Learn from others mistakes, you don’t have time to make them all yourself.”. This is a great video for teaching, thank you for your honesty!
By far one of the most in depth and informational videos on RUclips! Keep the long vids coming! Subscribed just from this one video!
Respected and congratulations, for your patience and your perseverance!!!
Excellent video breakdown of trenching, carb tuning and several other spot on tips. Your logical, methodical approach is to be applauded.Thank you for raising the bar of excellence on the net.
Best tuning vid I could find so far
Keep up the good work dude 👍👍
Hey this is GY6 Super 6 doing a good job fair years ago I did have moped Tyler Myers put a 70cc jug kit on it and change carburetor rebuild a cylinder head and had a lot of success I'm back into it makes me feel really young again keep up the good work technology is unreal my goodness have fun and be safe you got my vote Steve from Annapolis
Electron send this man some credits for the amount of wear and tear also the tuning of your carbs great video
Awesome video, shows the ups and downs that some guys font understand when getting a scooter to be fast and reliable.
Hey, love your work and bike, keep it up!
oh my god, i feel you. my zip acting exactly the same everytime i put new stuff on. i think the concept of my scooter of "breaking in" is in literally breaking stuff to havoc.
anyway love to see your videos again
Bro that’s the way we live 👍🏻
Keep ya head up.. you are a Master
I noodle around (practice) guitar while watching your videos and have noticed when your scooter is running its best and at full throttle, it is a near perfect A note... Thats taking scooter "tuning" to a whole new level... As always, very informative video.
Nice. Guess I need to carry a guitar tuner or attach a pitch pipe to my helmet. Do some scales for me. I just complain about not playing fast and then get bored with scales 30 seconds in. lol
@@49ccscoot It sounds like you will have some practice time while waiting for scooter parts... I'm new to the scooter world as of September (05 Stella Fireball and a 21 Buddy 50 for the wife) and I already know the pain of waiting for the UPS man... Happy Holidays
@@MarkSmith-rc8bx Merry Christmas!
cdefgAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA# AAAAAAAAA LOL
Thanks for the video i did learn allot with you along the way.
Keeping it real-- behind the scenes this is progress and note book is vital without question
Nice video as always! I am feeling your pain brother.. All to familiar feeling.. Anyway I hope your tear down goes well and I look forward to seeing your next update!!
Man, this video started out so much better than it ended. Friggin sweet vid about tuning a badass Lectron carb on a scooter ends with stripped crankshafts and more leaky cylinders. Jesus.
Thanks for the support Ken.
Really good video mate keep it up
i wish you have a good day ❤️
thank you for information 👏
Great and yes good 2 stroke takes time
Oh man I really feel for you on this. Huge $$ carb then crank/hgf...
I would be really downhearted at this stage so stay strong big man 👍
Thanks. I'll get it back together.
Cool video of you 😁
am i going to bash you for your carb spring error no .a big no .i myself and many others have made similar mistakes over the years :) i,ll been riding 32 years and working on engines for even longer ,i,ve yet to own a car ,and im 49 . big respect for leaving it in .as you could have easily edited it to vanish :) keep up the good work , and regarding the engine issues ,when it rains it pours . but im sure you will sort it out :) merry xmas and a happy new year :) lets hope 2021 is a good year for everyone :) regards from wales.uk
Thank you. Happy Holidays to you as well.
Brooooo glad you said it lol I hate changing the carbs or even taking it out! It's soooo annoying!
Ps greatly appreciate your videos honestly and effort in making them !!! I’ve been with you every step of the way from your first purchase of the tpr cylinder to the mvt ignition to the water pump and al the variations and modifications, absolute gift to the scooter community we greatly appreciate you ! Not all heroes wear capes ! Some ride scooters 🛵💨😎
I appreciate that!

Put aviation fuel mixed in with highest octane gas. Start light on adding. I ran it straight on 8hp Briggs/Stratton motor on a 1/2 hp mini bike frame as a teen. I burnt out exhaust and put 12 inch straight pipe that blew flames on gas release.
I had to reinforce front forks with welded on metal flat pieces on front/back of fork. It flew down the road! Lol
In pasturetest ride my 6’3” tall father was drug behind scooter until he finally let go of gas/handlebars.
I kept tools in pocket as when it backfired, it blew carburetor loose from engine…. Lol.
Eventually,I blew the motor and it froze up. If I changed oil before each ride, readjusted carburetor. It may have lasted.
This was 1980…. Hahaha.
I have been using electrons since late 90s early 2000s on drag bikes they really were different beast back electrons are king everything they say is true i sat a whole lot of time behind a flow bench with mikuni, Kehans,Keansburg, sudco,oko,they do as they claim
Woow bret got a lectron and the video dropped before Christmas this is amazing timing I was begging to think you abandoned the tpr project!!! After watching this video in it’s entirety I’m frustrated for you with this carburetor thought it would be wonderful with amazing reviews and performance. To be honest seems like standard jetted carburetor will be sufficient with less headaches . I wanted to purchase smart or lectron carburetors because of all the hype of no jets no tuning but after seeing this I think I’ll stick with the standard carburetors especially for the price !!!! Lectron don’t believe the hype !!!!!
good tip for heating the rubber is to put it in hot water insted of heater gun that tends to dry out the rubber.
ive always been curious about the Lectron carbs. the price always pushed me away from them though lol
That's the amazing thing about 2 strokes, you can put a bigger carb on without having to get new cams or alot of head work done
I wonder if you're getting binding where the cable is exiting the shortened tube. It looked like it was taking a fairly severe angle as it entered the carburetor and it may be dragging along the edge of the cable tube
It's possible, but nothing is wearing there so far. I could use a bend that isn't so sharp, but it would ruin my storage area. Not saying that it's not at all due to my setup, but my understanding is that it's a known issue that stiffer springs are needed with these sometimes. They sell them on their site. Costs $25 to get a medium and hard with shipping. Seems like an extra spring in a $450-500 carb kit wouldn't make that much difference, but I guess if you can get suckers like me to pay you for extra springs then it makes business sense.
I've seen people lube their carb slides.. just to get them more snappy and for a better throttle response.. worked most of the time
You should try the eprom for ur digital ignition. It helped me flatten the carburetor issues..
Did You Spray oil On That Plate its might help to lower it down i have got couple plates what are not come down so easy but oil helped a lot and i have seen peoples make surfise clean in lathe
Wow dude maybe you should make your own crankshaft that cheap Chinese steel Japanese or a little better and you got my vote dude I thought I was going through a whole lot everything breaking keep up the good work you got my vote super GY6
i have the same thing .. tried 4 different carbs, stage6 pwk 21 and 24, OKO pwk 26 and now have a Polini Pwk 28 which has NO POWER JET and it does the same, but slightly better... they all do that no matter what settings... from half throttle to full throttle the only difference is the sound, a boggish kinda sound and no difference in power.. mine goes all the way up im sure lol.
used to get a rich feel with them on the top end, started sputtering no matter what setting as well.. solved that by changing spark plug from br9es to br9Eeg.
I have been told that the thing with the power jet is so you can lean the main jet as much as possible, to gain that maximum lean power... then the power jet just gets into action to help cooling off with a bit of extra juice at wot.. havent tries leaning as much as possible tho ..
Thanks for the comment. The thicker sound changed to more of the throttle position after I got full travel, but still always sounds that way. I don't expect that it's something to be tuned out. Just not something that I'm used to with any of my round slides where they take on a different tone that doesn't seem to be closely related to mixture.
es type is shit.i recommend to use denso w27 esr.eg type is made for race so only full throttle.irridiums are expensive garbage too.
Hi Brent. Great video.
A suggestion. Perhaps mount a camera pointing at the Lectron so you can see if the power jet is actually pulling fuel up from the bowl. 30mm is pretty large so the carb might not be getting sufficient vacuum to pull the fuel up from the float bowl.
Its not an issue if it isn't because Lecton can always supply a rod with a taper to suit. Get all the info you can at different throttle openings and lectron can use that to give you a rod better suited for your bike.
And Merry Christmas too
I was thinking about trying to film the carb so I could see when fuel moved. Can't say I really thought about it not making it to the power jet. Not sure how well I can get anything aimed there, but I may try it when it's running again.
Merry Christmas!
@@49ccscoot Only need to point the camera at the clear pipe to see whats happening. I had a similar issue using a 28mm PWK. Its power jet was using nothing. It was only when I dropped down to a 24mm PWK that it generated enough vacuum to pull the fuel up to the jet.
@@gpzephyr Right, just an awkward spot for a cam perhaps. We'll see. Thanks.
air cooled, 2 ring. LOL I know its not where ya want to be but whew you putt'n in some real gruntin on this thing.
Interesting to compare the "extra premium" carburetors- Lectron vs. SmartCarb. Maybe hopefully someone will send you a SmartCarb to test. These things are too expensive for the every day average guy to mess with it seems. But they do have pretty big advantages.
You could have gone for the SmartCarb, it's an improved variant of the Lectron at similar price.
Awesome video as always!
It was tempting. ScooterTuning carries Lectron, and I do appreciate that they give me a break on parts. Price didn't really influence this decision, as I still paid a small fortune for the Lectron. As it turns out, my experience with the Lectron hasn't exactly been great publicity though.
@@49ccscoot I understand. Best wishes for future projects!
Great video! I've watched a few of yours now and love the detail you go into. I have a question which is unrelated to the video's content but I have to ask. Do you know the colour code of the powder coat used on your wheels. I love that too. :-)
Thanks. I picked it out of a book at the powder coater. I still have the receipt, but they never put any info on the color there. I'm hoping to get another set done myself, and basically I'm going to hope that they can look up what they used. All I remember is that is was called either "neon fluorescent yellow" or "fluorescent neon yellow". It's very bright in person. You could probably go to a powder coater and tell them you want the color used on the Menards NASCAR. That looks pretty similar and super bright.
@@49ccscoot Thanks for the fast response!
i've had a 28mm stage6 r/t pwk carb (flat slide nd with a power jet) on a 70cc stage6 sport pro mk2 (aluminum, one piston ring, high revving)
when i started tuning it, after some time, i just disconnected the power jet lines, so the power jet stops working, made it easier for me to tune the carb, easier way to tell the mixture it was having, and just changing the main jet and needle positions was easier than playing with it, trying to find the best jet and needle position to work with the power jet (the power jet wasnt adjustable), also, the bigger carb thing, i've had the same thing with my 28mm, that about 3/4 of throttle is the same power like WOT, just that WOT makes more sound, dont know why, but it was the same. Also the thing about the bigger carb is that it really shaved off a lot of seconds from my 0-50mph, with a yasuni c16, that bbk, and the 28mm carb (no work to the transmition) i was making 0-50 in about 6 seconds while with the same setup just a different carb (17.5m dellorto phva), i didnt count time when going 0-50, but it felt a lot slower, thats my experience if it helps
also, i used a 360 intake manifold too, a different one tho, i dont think you'll have problems with this one, but my problem with a 360 intake was that when on bumpy roads (gravel, dirt roads) the carb would fall out with the rubber boot out the intake housing, so i made a little bracket which bolts up with the cvt cover and acts something like a washer under one of the carb float screws, altough yours is a different engine and a bit harder to do a bracket from the cvt cover, mine was a piaggio long block
also, great vid, thank you
17.5 to 28 is a massive jump! I think with mine the no difference in 3/4 to WOT is telling me that I don't need a carb this big and the 25 was fine, but I want to give it a chance to see what happens if I know the engine is OK and get it in a good state of tune.
Hey I enjoy watching your videos I have a question to the carburetor that you put it on the moped will it fit a 1983 Yamaha QT 5050
Hey, thanks. I'm sure it could fit in a custom application. It wouldn't be a great choice to use a 30mm carb on a 50 if it's anywhere near stock, and I wouldn't think it would fit without a different intake and new filter at least. It's 50mm on the inlet side and 37mm on the outlet/engine side IIRC.
I really hope that carburetor is worth it it doesn't look like it's going to last long with that rubber intake is going to collapse on you after a. Of time with the heat
I'll be honest on the dirtbike carbs they have came along way I always used there carbs on drag race applications they were known for two things being able to idle and deliver a great amount of fuel no in-between with that being said its been along time since I used or tuned a carb based bike
Should try anti-seize on the splines prevent galling
I have a 36mm Lectron on one of my KTM 200s and a 30mm on my other 200 They were set up for the bikes, but I still needed to do a full turn out as there was a ton of spooge out of the pipe. Quite likely due to my mainly slow, technical riding. I've never had or heard of others with the sticking slide issue. Perhaps you received a faulty carb?
would be nice to have a coparison with lectron and a 30mm PWK flatslide carb.
Port n polish the head n you got the triangle of flow, intake, process, exhaust
Shortening a spring stiffens it, so you could try cutting off 1/4" at time until it pops the slide down.
I thought about that, but figured with my luck it'll just shorten it enough that it still feels soft or doesn't return well.
Instead of using filter oil, look into getting an "Outerwear" prefilter cover. They're $15 on Amazon. Stops extremely fine dust particles and is hydrophobic. I have one on my Uni filter on the Zuma bug-eye
Only make adjustments 1/8th turn on power jet at a time.
hello i watched your video here and decide try different carb. so i go on ebay get 21mm flat slide power jet carb. it was less than 40usd delivered. had to cut away part of the rear plastic just barely fit. but i am glad i did. compared to the 19mm i had it runs so much better. it came with 3 different jet setups so i just left the one in that was in witch is the medium. i wanted to know what you think of the importantance of or is there a use for the booster bottle thing. i have sr 50 2006 spiderman edition with 70cc malossi full circle crank.
Don't bother with a boost bottle IMO. I have made them and used them myself on multiple 2Ts. They were effective for me on piston port 2Ts. On case reed inducted 2Ts, like my scoots, they didn't offer any real benefit that I could tell.
I was going between the lectron and smart carb.. I'm not sure if there is much difference between them. Same designer. Ended up with the smart carb basically because I could get the 28mm for my big racing 88 build. I'm sure 30 would have worked great too but I like to stay on the small side for velocity.
Hope it goes better than my experience. Being a little smaller may help. I'd like to see if the SmartCarb works different, but I don't have much desire to buy another ultra-expensive carb after this experience.
Brent i have had an issue with the slider not returning polished up slider then idle came back. Crankshalf bolt has undone self little to cause this my rollers jammed to caused this!
I was thinking about polishing the slide, but didn't want to alter anything. I may give it a very light polish if a stiffer spring doesn't solve it (already have them on the way from Lectron).
I've been there twice trying to tune a carb that either won't close or open all the way.
Try cutting small piece of the spring
I don't think the problem with the crankshaft at the end is caused by the nut not being tight. A friend of mine with a brand new tpr 86 kit, had the same problem with the Top performance crankshaft, and he changed it 2 times, but it kept happening (with the complete over range malossi kit). So my conclusion is that top performance is producing faulty crankshafts. Also i've heard from many people the same thing occurred. Maybe you should consider buying another crankshaft from a different brand like 2fast, but it's pricey.
Waiting for the next video, greetings from italy!
Try it with some heavyier rollers it dont have the right rpm at higher Speed IT IS for a 86cc little Bit to slow with friendly greetings from Germany
Still Good Video
I need a wideband O2 sensor, well could use one to get it going properly, some reason I feel it's a bit lean up top end even if it will turn over 10k, it seems to be a area around 80% throttle, EFI would be nice, but $$$, I never thought it would be such a headache, I tried a 90° tube, about 12" total, with velocity stack on the end, it would only idle, no throttle, I'm guessing it leaned it out, I would like to use that with a filter, to get cooler air, I have also had issues with the seat bucket hitting the carb, breaking intakes, I cut clearance, but I'm thinking my issues could be with carb angle, I think it's the wrong bucket, it's not the original seat or bucket I guess, I kinda got s.k.roued on the deal, it supposed to been a running scoot when I paid for it, gave the guy cash, and he was gone, (from his house!) He left me there to load it up, he was in a rush, I should known, I had to rebuild the top end, it had no compression, so I big bored it! But I have another scoot I'm getting, and another engine, I'm building one maybe a stroker, with my 52mm bbk, big valve head, for 95cc, either use it in the scooter I ride now, or a 150in it, or the other one, the dependability of these china scoots, I need two! Haha, so one will hopefully be ridable! I'm hoping the 86-95cc will run about the same as a stock 150cc, I wish they made adjustable jets!! Haha,,
I think you did everything very methodically and as best you could with the Lectron Carb and for the price of the Carb a little more information should have been provided which would have helped significantly.
Go for the A class parts! Polini or Malossi. Then everything remains intact.
See what you have already had to do about the cylinder head. And the broken cylinder. TP just isn't strong enough.
My plan is not to upgrade the TPR with say a better crank... but build something totally different if I can ever afford it and things are in stock. I just need this thing to stay together so I can at least find out what happens when the Lectron is in tune.
you should try comparing your lectron with dell'orto VHST 28 or a VHST 30, both have flat valve
I'd just like to get the Lectron right and not touch any carb for a long time. lol
🤣🤣🤣
btw i think that dell'ortos are easyier to tune or maybe as an italian, i usually dealt with dell'orto or Polini CP carbs. For a tpr86 i would definitely go for a 28 VHST. cheers and thanks for the nice content!
My gosh, you spend sooo much time tuning, damn
I have no desire to. Carb tuning is one of my least favorite parts of this hobby. Most of the time a jet and some screw turns and maybe a needle clip adjustment and you're off. Sometimes they're difficult and can't seem to be tuned with any reasonable amount of effort. The Lectron took that to a level that I had never seen before.
I brought up the idea of using a Lectron a while back on the Forum. When I wrote it apparently they were all too big, even the KX65s. I’m glad it all came full circle!
Yeah, I forget the minimum size but I don't think they had 30mm then.
I built a custy-bicycle w a ktm 50 sx engine,(case reed) was wicked until put a 2 mm larger carb. on it.
Now no crank? Thinking either air leak or wrong jet? Any advice?
There shouldn't be any reason it wouldn't fire up with a 2mm larger carb. Always a good idea to leak test 2Ts, but if it went from running OK to no-start with just the carb swap, I'd have to guess at a carb issue first. Make sure the carb is getting fuel to it. Still, the quickest and easiest first check for any no-start is a spark check.
@@49ccscoot Thank you much for the quick response. Yes, I checked spark, it actually seemed as if maybe it is a spark issue. I only saw the spark about one out of three or four try's w the kick start. Must be the stator possibly, cdi.
1:01:13 Did you only write that only ob paper but not make the adjustment? Or did you edit that out?
Just edited out. I see that it does look like I didn't do it though.
wow that crankshaft all ready :( you going to be fitting a new one or going to keep with that for now ? not played about with the velocity carburetors tho look like the oko 28mm carburetor i have been playing about with
I'm gonna keep it and hope that the grooved area doesn't become a point of failure where the crank snaps.
@@49ccscoot do you think it got the groove due to variator nut going loose ?
@@mrchilled85 If everything is tight, it shouldn't spin. Some variators don't even use splines in the ramp plate.
@@49ccscoot i was thinking that with some ramp plates but was not 100% sure :/
Just bought a trike 2020 q6 ice bear 150cc 0 miles still breaking the engine you can say. Has alittle than 200 miles. I'm a 300lb guy n that baby handles me sweet!!! Only thing I notice after hours or riding it kinda loses power. Any advice on what I need to do to keep up the power hp ect. Or any advice on what I need to modified upgrade?? Any advice will help. I'm definitely looking to add power n be able to keep the power as well. If possible.
Losing power after hours of riding makes me think about heat related things. One common thing that happens is the CVT gets hot and over time the contra spring will fade. That lowers RPM. Sometimes a little, sometimes quite a bit. If you have a tach, pay attention to it as you ride. Make notes so you don't second guess yourself. If you don't have a tach, it is a good tool for troubleshooting things like this and for tuning.
Wd40 on the intake boot makes it way easier
it seems your rollers are kinda light if your going for top speed instead of acceleration
Can be used at KYMCO Super 8 125cc 4 stroke 🤔
I would suggest contacting Lectron. They sell different carbs for 2T and 4T.
The motor sounded good just do the fine tune stuff
I'm sorry things went the way they did.
I wonder if--instead of using a plain spacer behind the variator ramp plate--a splined section could be either cut from an old ramp plate, or a kickstart spline. Then the splined washer could be tack-welded to a ramp plate, away from the edges, so that it doesn't affect the temper. That way, there will be a longer spline contact.
No RC-1 build for you? : )
You'll see in the next vid, but that's what I did.
Maybe someday.
Is it possible to put a 70cc cab in a yamaha razz 50cc 2 stroke?
There isn't really a 70cc carb. You could install a larger carb. I don't know the Razz well, but I know the DellOrto PHBG carbs fit the Jog/BWS/Zuma fairly well.
Again a little silicone grease is safe to lube yer slide too.
I’m curious as to why you don’t tune mopeds? They look cooler and are a lot more versatile when it comes to road and off-road riding. Better handling and easier wheelies. Just curious 🤨
I have 1 moped. It's my project SSR, but it's a 4T. I've been used to scooters and I like them. They also tend to be more plentiful here. Nothing against mopeds.
Hello, the Carburettor from Lectron, do you think it was better or what Deloto dyden nemmernat set
I think the better carb is the one that works.
Do you like Delorto Best or Lectron
@@bp-tuningaeroxlc-dd6474 Dell
@@49ccscoot me too … Delorto is much better on 2stroke Scooter you have.
If you don’t think it’s tension in the cable you will never get it right. You can prove this by pulling on the slack cable on top of the carb. There will not be tension in the carb slide. Boom 🤯
More oprn is leaner so why would you go leaner yet when it sounds off preveouse performance?
At one point I was just trying to see how much the power jet adjustments were really doing.
I got a 90cc Eton four wheeler that looks to be a gy6 format can I mount that on a scooter a build off of it
Possibly. Some of the 50-90cc ATVs use Minarelli two-strokes that can bolt in place of scooter engines. I had a Polaris 90 engine in my old Keeway Venus scooter. Some engines have a gearbox that doesn't convert well to scooter use.
@@49ccscoot thanks
To be honest a 25mm carb sounds about right for your 86cc engine, I think that the 30mm is not going to make a big difference on your setup (I hope you prove me wrong).
For example I'm running a 30mm flat slide on my 125 cc setup.
i also looked at the Lectron carb a long time ago but the price tag scared me away, so thanks for trying it out and sharing it with us.
I really don't think I need a carb this big either, but I've heard it so much that I had to try it.
he can better try polini cp.it works same as keihin so u can use jets too but there isnt a perfect carb just only brainwash.or u go with efi.
@@jenny-masterchef It could have changed since I've last paid attention, but fuel injectors don't tend to like oil pre-mix.
Poping and pinging is to lean, bogging is to rich. On full throttle the pilot jet is not used only the main jet. Check spark plugs, if to rich unburn fuel, to lean whitish color, good is dry and light brown.
2:56 what is with the wear on the round slide ... kinda says something was not right with it's operation .
Probably the 20,000 miles on it. lol
Little dab silicone grease will let the boot spin and not hurt the rubber boot . ....
I don’t like how those manifold make your carb bounce around I made a metal piece that screwed into old stock airbox screw and propped up the carb and kept it from bouncing
How do you polish the slides
Knock off sharp edges/imperfections that may affect motion and then use a very fine sandpaper and metal polish. Wash thoroughly and dry to be sure you don't get any dirt or grit in the engine or carb. Obviously done with the slide out and disassembled.
Are you checking the spark? He should be a light orange color, am I didn't wrong
Spark is good. It's white/blue, bright, and consistent. This bike runs great with another carb on it and I've swapped back and forth.
You happen to have pod or stock type airbox you want to part with my little adlet 2stroke needs something any recommendations are seriously welcome
I don't really have spares. Unless you have something with a big carb, then just get a stock replacement. AdlyParts has them and you can probably find them searching for Polaris 90 airbox or something similar. Steer clear of the cheapest Chinese airboxes that are being sold as replacements.
Will do thank you for advice . I gotta figure out why when it sits it leaks fuel now
@@NOFx420x Float height would be my first check.
Bowl screw was open . Put stock box on do you oil black foam filter and do you have a good video on tuning the carb hard to start very cold but once running a little bit and warm very responsive
@@NOFx420x Glad it was that simple.
It's good to oil the filter, but TBH most people don't.
I've got some vids about general tuning. 4 short parts, this is 1. ruclips.net/video/UipC6DLD-EE/видео.html
If it's only symptom is being hard to start when it's very cold, that's not totally uncommon for the auto-enricher stock carbs. Sometimes they just aren't as effective as they should be. Maybe richening the idle mixture would help a bit though.
The carburetor looks really Snappy but they got to go back to the drawing board you're going to have trouble with that once it heats up cools off heats up cools off you can have nothing but vacuum leaks it's going to run lean on you be very careful far as I'm concerned put a good old-fashioned Mikuni carburetor on their be done with it
Please try Malossi crank or pollini
I'm not really sure how much this is the TPR crank's fault. I think the crank needs to be made so it can give a little and not be super brittle, where the ramp plate probably can be harder. Not saying this is the best crank, but I'm certain that any crank can be damaged if the nut comes loose.
i've had experience with a stage6 hpc crank, and a doppler endurance crank, after the doppler, when i got the s6 hpc, it really felt like the quality of the hpc was muuuch better, it also added both side nuts in the packaging, and a gear for the water pump (piaggio engine with the water pump near the cvt), it lasted for about more than 2k km (1200miles) seeing 2 engine seizures and then i sold the scoot, dont know how much longer it lasted, so from my experience i would recommend the hpc
@@SeNu420 To be fair, I don't know if the first TPR crank would have failed if the ramp plate didn't split and it lasted over 2,000 miles for me. Not at all claiming it's the best. I think it qualifies as good enough if I didn't have other issues.
You need a fra k without splines, the Rpm Eats em away, sad to see
I've been through this chaos where every part of my 90cc jog starting to fail everytime i do tuning. Sad times :(
It just seems to go that way sometimes.
@@49ccscoot just when it seems to get better everything starts to break today broke my engine case between the vario and clutch because i forgot to put in 1 cvt cover bolt but oh wel thats how it goes somethimes i gues . it sucks that the cranck is already broken and that after a big expense on a lectron but keep up the great work love the videos .
@@samydarghazi4046 Not cool, but at least you're here to tell us about it. It could be really bad if it snaps totally in half.
I believe you made a non intentional mistake, and I am referring to the metering rod explanation. Their both metering rod’s, the lectrons design is superior and easy to adjust.
Essentially they are both metering rods in that they are rods that meter fuel. However, anyone that has been tuning more traditional motorcycle carburetors for a while is likely to refer to what is in a standard carburetor as a needle; which is generally short for jet needle, working in conjunction with the needle jet. You can find these terms in things like DellOrto's own carburetor publications.
