Can anyone help identify this kart, my buddy picked it up off marketplace, no obvious identification on the frame.

I'm in need of a new race suit soon. Keen to get something that looks good without breaking the bank. I'm leaning towards your average Sparco/OMP suits, but have seen Etsy ads for custom factory LN/KR/Tony Kart suits. Apparently these are CIK/FIA Level 2 certified, but they seem a bit too cheap to be true. Has anyone had any experience with custom suits from places like Etsy? If so are they legit? Things to keep an eye out for? Any advice is hugely appreciated

Dev disclosure first, because this sub has every right to be tired of app posts. I'm the developer, it's a commercial product, and I ran it by the mods before posting. No link in the body, I'll drop it in a comment if anyone wants it. We are spending real money (actually a lot) on driving in real tracks with kart racers, car racers and professional sim racers, so please, give it a try without pre-judging (and also please, be rude if you feel so in the comments, we really want to improve).

I want to be upfront about what this is and is not, because I keep seeing "AI analysis" apps and honestly most of the skepticism around them is fair. An AI coach can only work with the data you feed it, and if that data is a phone GPS at 1 Hz, it is not going to tell you anything useful. You could load that into ChatGPT yourself and get the same vague answers.

I did not build an AI coach. What I actually spent the time on is the boring hard part, which is getting trustworthy data out of just a phone in your pocket. It fuses the phone's motion sensors at 100 Hz with the slow GPS to reconstruct lap times, the racing line, speed and cornering G, with nothing mounted and the screen locked. That is a real sensor fusion problem, not a plotter with a nice theme on top. This comes from my background in engineering, and interest about inertial systems and aerospace projects I worked on, moved to my hobby which is racing, and that I do not come from a wealth family, so + thousand euros data-loggers are not a thing for me...

Two proof points that made me feel it was worth sharing, out of a growing pile of real sessions rather than a couple of cherry picked ones.
First, when we could get ground truth, it held up. On one session I had official transponder timing to check against, and the app matched 20 of 24 laps within 0.1 seconds, with the four misses being the in and out pit laps that the transponder times on a separate loop. So the lap timing is measured, not guessed.
Second, and this is the part I personally find most useful for karting, you can compare your real laps against your sim laps. I practiced a track in Assetto Corsa beforehand, logged the real session with the same tool, and the speed traces, the line and the friction circle lined up closely.

That is something a generic AI coach cannot really do, because it is about the measurement and the comparison, not about prompting a chatbot.

We keep stacking more of this up across different tracks and vehicles, kart, car and sim, precisely because one or two good results prove nothing on their own. The more varied the data we throw at it, the faster the weak spots show, and that is exactly the point right now.

I'll be honest about the limits too. It will not magically find you two seconds. If you are a couple of seconds off pace, that is driving and setup, and no app replaces seat time and a good coach. What it does is give you honest high rate data and a real sim to real comparison, so you can see what you are actually doing instead of guessing.

Genuine questions for you, and I mean it, I want the honest answers and not the polite ones. For those of you already logging with a MyChron or an Alfano, is there anything phone data could realistically do that would make it worth your while, or is a proper logger just always going to win for you? (considering prices). And for the ones who both kart and sim, would a real sim to real comparison actually change how you practice, or is that just a nice gimmick on paper?

PS, since it comes up and I would rather say it than have it assumed. Yes, we use AI, mostly for testing and code coverage, the unglamorous stuff. The estimator and the sensor fusion are real engineering that took a long time to get right, not something generated by prompting a model. I would rather be straight about that than pretend otherwise.

If you are interested, please let me know in the comments and I will attach the links, videos, screenshots, and whatever you would like to see.

Thank you so much beforehand, I really hope that this do not annoy you :)

I am 15 and racing other people indoor e karting. i get light tapped from behind a lot which is normal I think but occasionalt I’ll get bumped almost into the wall one time into the wall. after they just go and say sorry. the staff doesent do anything.

is this normal

and do they mean the apology.

Hey folks,

Just bought my first LO206 kart and stand from marketplace, everything looks VERY clean and new except for where the rear bumper bushings insert to the rear of the frame. As seen in the pic, there is some slight flaring of the frame tube, is this a concern or a big nothing burger? The kart has been lifted by the rear bumper with a kart stand, but I think the bolt is bent as well.

Hello everyone, I have been doing about a year of karting now and are looking for an upgrade for my gloves. I had a look at all the different karting gear brands and would like to ask for any recommendations to the gloves you use. Doesn’t matter if it’s homologated or not, I just need a good pair of gloves that preferably have an external seams and last long. My budgets around 50 to 150 quid. Would love to hear your suggestions. I am looking to progress to ownership karting in a few years time for uni.

One more thing, is it true that minus273 is no longer a reputable brand to buy from? Been hearing reviews about their gloves falling apart and all that jazz, heard they used to be really durable.

Many thanks.

Morning guys.

New kart purchased, shop have given it the once over, race gear purchased. Seat time this weekend. Very excited.

So last weekend I ran my kart up and down the road for 10 minutes for this first time.

The seat got very hot and the acceleration was very boggy. I checked the spark plug after and it was very sooty. Have googled a few things and it noted that this could be because a lack of air. Checked the air filter and it was damaged. It was bent, I would also say it was quite dirty and dry.

Does replacing the filter and spark plug sound like to be enough? Should 10mins of running time have cause all of this or should I be looking at other areas also to check? If so what should I be checking/looking for?

As you can see above not new to Motorsport but new to karting and maintaining engines.

Appreciate everyone’s help!

What tire size do I want or need for these rear wheels , backyard dirt oval. Thanks.

I was told “arrows or something” on marketplace and it has FC101 at the front. I can’t find any other hints on the chassis

Hello!

I recently picked up a 2014 CKR SG2 chassis with a prd fireball, over all the condition was pretty good and then motor runs well as well. However going over it and getting a list of stuff to get for next season I had noticed a small bend in my nerf bar which got me worried about the frame being bent.

I checked the frame before buying it as well as after and as far as I could see I didn’t see any major or notable bends or kinks, I was wondering if someone would be able to see if it’s bent or not

If I need to strip it down to properly make sure it’s not bent which is what I was seeing I’m able to do that as well, there’s just not many karting places I’m able to take it to to get professionally looked at near me.

I was planning on replacing a lot of the drivetrain and steering components anyway to refresh to kart so the condition of those are not super important!

Thank you!

I just got this kart off marketplace for 1500 and I wanted to know if I got scammed or not and what is a good price for it? It's got a rotax max pre evo motor with Hoosier wheels. The frame is amazing and the only damage seems to be scuffs and little holes in the plastic bumpers

I've been putting together a playlist of karting videos from different tracks around Southeast Asia, and it's now up to 17 videos covering 11 tracks.

I thought I'd share it here for anyone interested in karting in the region, planning a trip, or looking for new circuits to try.

Playlist: https://youtube.com/playlist?list=PLW8XWeTDcH4WT7bM7yJN4gQQz1gmAvA5l&si=LLbQ41GLnNAjIEyn

I'm the creator of the videos, just to be transparent. I'd also love to hear about other karting tracks in Southeast Asia that you'd recommend checking out!

Bonjour!

Je suis en France et j'aimerai savoir si ce moteur existe toujours, si oui connaissez vous des revendeurs en Europe ou un équivalent car ce moteur je l'ai utiliser il y a 10ans + et c'était juste une bombe ! J'aimerai vraiment pouvoir revivre cette expérience :) Merci d'avance

Hello,

I am looking for a partner for the November 22nd endurance race. I did the race last night solo as a rookie and ended up coming in 15th out of 19th with a best lap of about 35.8. I need some help, 200 laps was too much for me. If anyone here is able and interested in joining shoot me a DM. There are 7 required stops during the race where driver swaps are completed. 190 pound race minimum and the venue has weights.

Thank you

Hi everyone! I’ve been building RaceFX to simplify and speed up the process of creating telemetry-overlay race videos.

Why I built this: As a kart driver, I was tired of the slow, multi-step workflow required just to post a video: extracting footage with the GoPro app, overlaying HUD telemetry with RaceChrono, editing clips in a video editor, and finally uploading to YouTube. My ultimate goal with RaceFX is to handle all of this in a single app, with just one click. What it does currently:

RaceFX processes onboard racing footage directly in your browser. It detects the race/laps from GPS data and can generate: Full Race with HUD (Speed, current lap time, best lap, lap counter) Selected Laps Highlights Theoretical Lap Privacy & Performance: No upload needed: Your video stays on your device — no need to upload multi-GB footage to a server.

Desktop First: This initial version is web-based and optimized for desktop computers, where processing runs up to 4x faster. (An Android APK for mobile devices is currently in development). Looking for Beta Testers: I’m looking for people who record kart sessions with action cameras to test it with real footage.

🔗 Try the beta here: https://racefx-race-fx.vercel.app/

Any feedback on different cameras, browsers, performance, or anything that breaks would be extremely helpful!

So, aside from a couple times in a rental kart and a day in a 2 stroke I have zero karting experience. But I have raced cars.

Logistically and budget wise seat time (training) in a kart is much better. So I was wondering how much effect regular kart sessions could have on my lap times in a car?

Edit: My car control is good. But I tend to struggle with lack of confidence when I have been out of the car for a while. Thinking a have to brake sooner, taking a corner slower than necessary.

This is the chassis tag from my Tony Kart. Can someone help me identify its age and any other specifics I should know about it?

Thanks

This is my first kart, noticed after purchasing. The previous owner claimed there were no incidents or crashes with the kart.

Trying to find more info on this Kart so I can restore it. Anything helps!

My Tony Kart with an X30 is having an issue starting. The engine will start with an external starter. That’s not an issue. Where I’m having the issue is somewhere between the battery and starter motor.

When I push the start button, I get nothing. Zip, zilch, nada. I’ve checked all my connections. I found a 5a fuse that was burned out and replaced it, still nothing. I thought it might be the actual starter button, but I’ve jumped it and still nothing. It has the electronic ignition, so I suspect there could be an issue there, but again, the engine will run.

I’m very new to karting and my automotive electrical skills are not overly great. But if you have suggestions at to where to start testing/checking, I’d really appreciate it. I don’t really want to start replacing things just to find the problem.

Could the kill button be causing my issue? When it’s in the “down” position, the engine won’t fire. But in either position, I can’t get the starter to turn.

Thanks in advance.

im trying to find an asseto corsa or kart racing pro track mod for al ain raceway, i want to practice before my first race there in i think just over a month,

so it would be really helpful if anyone has or knows a track mod for al ain raceway for either asseto corsa or kartsim pro

thx in advance

I went with a friend to a K1 Circuit. This is our 4th time, multiple races per session with their rentals.

This time my friend ended up crashing on a section they felt confident about since they’ve cleared it many times with no problem. They understand that crashes happen but they can’t help but keep reviewing the incident in their mind about how it happened since the section and the approach to section couldn’t have led them to a crash the way they did. My friend also comes from the world of racing on tracks and not new to racecraft. The crash led to damages to the kart. My friend is suspecting kart condition as a potential contributing culprit as the karts are not normally well maintained.

Having so many unknowing risky factors such varying as kart condition from kart to kart involving chassis, steering, rods, brakes, tire and such, without a detailed evaluation of the kart before or after you’re at a much higher safety risk than you anticipate especially if you’re a driver than tends to like to push the karts a bit to find faster lap times. Karts are also now electric motors so there is even more factors at play.

When you do crash there is no footage, there is no report. All they do is send the kart to a mechanics to evaluate on their own discretion on which parts you need to pay for. Additionally they seem to be more concerned about the damage payments than evaluating you for injuries as they don’t have a process to do so, but they are quick to rush you to the counter to pay for kart damages. There is no insurance waiver to be offered either. K1 doesn’t offer any sort of insurance policy as a waiver or even injury spot covered compared to other sports such as skiing or snowboarding.

Damages can add up quick and can really put hundreds on top of the races you might’ve purchased.

If you dive into their customer reviews there are a handful of accounts where many do feel poor kart conditions led them to their crash. Interestingly enough when you dive into the financial state of K1 Circuit they are currently in debt so in a sense it feels they are positioned to be incentivized to want to charge fees as traffic to their locations are not generating sizable profitable to offset. Hence the lack of a damage insurance option. To me this becomes a conflict of interest that should be kept in mind.

After this past session we’ve decided to refrain from returning to K1 Circuit unless we bring our own karts.

Decide for yourself. For us, the monetary and safety risk is simply too high.

Hi, recently me and a friend of mine bought a 125 2 stroke kart for really cheap.

The old owner said that it’s a CRG FORMULA 2000 from 1998, searching online we couldn’t find anything about it, so we started thinking that it might be some other chassis.

We need to restore it so we need as many information as we can get and possibly the mechanical manuals of it.

We also are searching for a new compatible braking system for it but we have no idea how to find it.

If you have any ideas on what chassis and year it actually is we would be pleased to know your thoughts
