As someone who started on 100cc then went to LO206, I'll give my five cents. If you're looking for a cheap, low maintenance engine that encourages pack racing and precise driving, LO206 is for you. However, it is slower and the pack racing can be a pain. If you want to go faster, run larger events, and be able to polish general kart racecraft, 100cc is better. It is more expensive and much more competitive as these engines are not factory sealed and you have to rebuild them every year if not more. IMO, 100cc is much more fun, but it is much more expensive to maintain. Or you say screw it and run shifter its your money lmao

this is such a excellent video! Thank you for making this, such an updated video! Keep up the good work!

Another great video, thanks for your work producing these!

EXCELLENT,THANK YOU GUYS..STAY AWESOME!

Thank you VERY much for this video. Ive been driving an LO206 for the past 2 years and have enjoyed every second. Its time for me to switch to something faster.

Thanks for this, it answered most of my quesstions

Your videos are helpful I have a new track about to open near me so I've been researching on what class I want to start out in. Waiting on the track to open so I can get more information on the rules before I make my decision.

Great job guys!!!

This helps a lot. I just drove a kt100 the other day with no prior experience in driving any race kart and it definitely was intimidating.

I learned 80% from this video 👍

For my 3 decades of street bikes, I loved the PJ1 blue label chain lube, AND we always lubed the chain at the end of the ride, warm chain the lube seemed to penetrate better, but then it cools and flings off LESS than lube and go. Simply comparing the chain guard fling off.

I believe the 100cc would a start for me for starter or 125 shifter,one or the other...thanks for info. Keep up the work

I jumped into karting on a CR125. And I had no idea of the costs of keep this thing on the track. Basically the same as the 100cc with tires and fuel. 6 hrs on the top end and 12 hrs on the bottom end before rebuilding can hurt. Plus I just Grenaded both. Cha Ching!!! But I love driving this fast beast. Great info video, guys. Thanks.

I started in RMax in 2001 @ age 40. In 2005 or so I finished mid pack in the RMax national finale race in Denton Tx.

Nicely done guys!

I've raced various classes and engines over the years, currently racing Endurance karts on sprint kart chassis with a L0206 as my main class with entries generally 30-38 per round for a 6 hour race, but sometimes run the twin L0206 class, which runs faster lap times and top speed then a 125cc (Rotax or X30), they are fun to drive. Useless info time the Iame KA100, the KA stands for Karting Australia and this engine was bought in to supersede the Yamaha KT100S engine, but the KA100 class is not very popular here in Australia.

Really enjoyed the vid! subbed

Coming from two stroke, there is nothing like running two stroke. The big down side for me was cost. You have to always have to have a fresh chasis and a fresh rebuilt motor. We did L206 but found it too slow. We now run Tilllison, which is also a 4 stroke. The Tillison is much faster and is non expensive. It is a growing motor and more racers are running them.

In the UK classes are a bit different but in general Rotax is the way to go, it’s more maintenance friendly than X30.

I am in my 2nd year of go-kart racing. 2nd year in the 206 class at my local kart club. I enjoy being in the 206 class and don't plan on changing class anytime soon. The 206 classes are the most popular at my local club. Some guys racing in KA100 and TAG actually got bored of racing each other every race and have now come back to 206. There are now no classes left really between 206 and shifter. The 2 local tracks we race at, the lap times for 206 are between 27-31 seconds. They are both small, twisty tracks so I don't see the need of ever going to a faster kart because the lap time difference won't even be much. From a financial point of view, the 206 is an affordable class that I can afford to race in no problem. If it wasn't for the 206, I probably wouldn't be racing. Fuel & tires are not a big expense like they are in other classes. The Hoosier R60B tires we are required to run last forever which is nice. I only used 2 sets last season in 11 races and I still have life left in them to use for practice this year :)

This video is very useful

Can you make a video on the different ways to set up a chassis? I am clueless to how that works

In almost every part of the country. The 206 classes are the biggest. If you're brand new, that's the class to start in. Absolutely the cheapest by far. More entries means more competition. Which means learning racecraft quicker. Also teaches smooth driving. You must drive well to run up front in the 206 classes. Most have a spec tire rule. Where I race. One set of tires will last the whole season. If not more. No engine rebuilds every couple races. The engines are simple and don't require as much tuning as two strokes. If learning how to race is your goal. The 206 class is the best. If speed is your goal. Go 2 stroke.

I'm new to racing karts but I've raced rental karts for several years before I got my own kart. For me there was a huge difference between racing rental karts and the LO206. I here you all say several times people could get board with the LO206 and I have a hard time believing that. I live in Phoenix Arizona and race at Phoenix Kart Racing Association (PKRA). Our track has 6 different layouts and we run clockwise and counter clockwise giving us 12 different configurations. The layout changes every 2-3 weeks. Thanks for your videos!

great information. i do have a question. i am looking into a used crg fs4 for the 206 class. if i am ready to upgrade to the 100ccclass am i able to utilize the same chassis?

Great vid. I’ll second that although LO206 is very popular, that doesn’t neccessarily mean they are everywhere. You assume they would be, but that’s not absolute. So call your local track as they might be on something different like a modified 4 stroke class, or a another stock class 4 stroke engine that isn’t LO206.

I remember an old freind who raced Nationals here in Australia in the 100cc Reed Light Class always said it was cheaper racing Formula Ford that it was racing Reed Light GoKarts. I am going back 20 something years so it would be interesting what the costs are today. But back then each tyre was $500. And you always had a set of Wets and a set of Drys on you at any time so you could switch them out when the weather turned suddenly. An engine usually last 1 or 2 races max. And it would be pulled down and rebuilt every Meet or every other Meet. That could cost you between $6000 - $10,000 depending on who rebuilt it and how close to the allowable tollerences it was. Biggest pain is that the Marshals had the right to pull it apart if they suspected you were cheating and check. And then would leave you with an engine in a million pieces and a race in 10 minutes and an engine with a broken cable seal which meant it couldnt be used that race. Most racers took 2 engines just in case a Marshal got nasty and tried that. I learnt early on that greasing your chains was a massive no no. You want them clean and dry so that dirt, dust and grime doesnt stick to them and cause them to fail prematurely.

Where do you guys buy your Karts from? Who sells the Sadi Karts?

What kart do you recommend for a heavier driver?

In regards to operating costs. You guys mention the costa for 100cc are higher and cover gas costs but what would you say the average race weekend and annual costs are controlled one another?

I started with rotax 125cc

I'm pretty lazy and I like comfort. Do they have like an Unlimited Class where I could put some wheels, and maybe a V-8 on my couch and race?

Are the chassis between the 2 classes the same?

I want to begin Karting just for fun, what do you recommend?

nice video.

Have you tested a 15hp + Tillotson 225cc RS ? Most have 17hp. Engine lasts all season and lots of testing. $1400 to buy. Just needs a $500 refresh in the winter off season. Or the ID-Engine 200cc 24hp. $1200 per season lease. They also do a 300cc 41 hp Shifter.

Where to look for used equipment in Texas?

finnally Also how fast do you think both of the engines use gas Thanks

2 Stroke cost for pre mix cancels out because the lo206 has motor oil changes. if i'm correct the kt100 and ka100 dont have an oil sump.

Can you buy one chassis, then move up changing motors ?

I am just getting into it. I was looking for an LO206, but wound up purchasing a KT100 locally. Turns out there's a pretty good KT100 class at our track. I've driven 206, haven't driven KA/VLR, but it seems to me that the KT100 is a bit of an in-between. Faster than 206, not as fast as KA/VLR; higher maintenance, but not a reed valve motor. External starter instead of the onboard battery/starter of the KA/VLR or pull-start of the 206. Definitely an older school 2-stroke class that isn't as popular anymore, but great bang for buck value. I'm loving it so far. Great video, as always!

I'm looking to get into the sport. Who offers classes in GA?

Is rotax any more expensive than the KA100? I don't see why KA100 even exists anymore, but I haven't been in karting in quite a while.

I want to start karting, I wanna start with rotax max. Any tipps?

what is the best class for switzerland?

In another video you showed how the L0206 is sealed, so all the engines are theoretically equal. This seems important for someone just starting to race, to know they are on a equal basis. With the 100 cc class you mentioned “blueprinting” and I am sure there are other mods, or tricks, or cheats to get a power advantage over the novice. Have you seen much outright cheating? I knew a guy that would pickup his extra weight after the race on the way to the weigh-in.

What if you are old, 6' & 245 lbs. have no chance in winning any race and just want to drive in track traffic?

Can i be any weight and race. Thinking about 206 or x30, im a bigger guy.

LO206 unobtanium class at the moment.

Lo206 doesn't exist locally for me in NJ So 2 stroke is the way to go in NJ

One big advantage of lo206 is the engine is sealed. So if someone is beating you it's not because they found some sort of advantage by tweaking the engine. With the other classes there is all kind of special magic to make a little more horsepower if you're willing to pay a lot so it may not be an even playing field

What class would you consider the upgrade class to either of these engine classes ?

How long does a 206 engine last? If they’re sealed do you have to get a new engine every time the old one wears out?

10:20 whats the little digital gizmo on the airbox?

Any kart chassis recommendations for 6’7 260lbs driver? Not looking to be be competitive but for fun. I go to mb2 but they are to small hard to steer because my knees are at the steering wheels and I have to keep my left leg up so I won’t hit the brake pedal

I dont know about the 100cc engines, but I have been racing motocross bikes (2 stroke) for almost 30 years and have always ran pump gas. Not sure why karts would require $20/gallon race gas.

Rotax max senior is the best way to start

So could you buy a lo206 kart and then switch the engine to a 100cc and still be able to race with the 100c karts?

I turn 36 next month and have been thinking about getting into kart racing? Is that to old? I plan on doing rental league for a bit and maybe move to an lo206 after that. Thanks for any tips or help!

100cc all day. Lo206 is definitely a lot less expensive to purchase and run though

What are somethings to look for when buying my first chassis I'm 6ft tall and can you run the same chassis in the lo 206 and the 100

Anyway to get a lo206 with a 2k budget

If your a kid 10 to 16 go for x30 or rotax

How bout some prices??? When you have to consider a racing budget, engine costs, rebuilds, clutch maintenance and parts....I'm coming from vintage karts.

I personally think, 125cc engines instead are great for both beginners and experienced karters…

How can I get intouch with you?

Thanks for vid. 100cc class it is …

I think somebody should put a drz400 engine in a kart and make a new class

OK....ok now

LO206 = 206cc engine displacement.

IMHO: LO206 is not too popular in our area. Fewer people to race and practice with. They are the slowest karts on the track besides rentals. As I have gotten better, I am bored with the slowness of the kart. I like the four-stroke engine, but it's so slow compared to everything else. 100cc is on the shopping list.

Obviously shifter. Duh

Another tip is do NOT buy an intrepid haha

Well this channel named didn't age well

Y'all blink alot.

Unfortunately we don’t have good race tracks in Michigan 🥹
