Kart diagnostic Driving help (video)

Hello all ive been involved with karting for a while im a first generation racer. simply put my dad has no idea on how to communicate with me on handling i tell him to make a change based off what i feel but thats about as far is goes sometimes. I’m posting a video someone took of my last race ( I’m the #26 kart ) and im wondering what do you see? i feel like the kart is under steering on exit. maybe im over driving the corner? just a discussion on what i can do to gain the extrs .2 to .3 i need to pass.

Disregard everything I just edited out. :joy: I thought you were the onboard when I first watched. How does the kart feel to you?

Break down entry, apex and exit feel if you can.

I am not a 206 expert but it feels like in some turns you are a bit late to turn in. You are asking a lot from the chassis and you could gain by being more gentle.

Hey matt kart just feels like it wants to wash out mid corner and exit. i will note i needed to go down a gear for this feature as well. entry feels pretty stable as well. if anything maybe a tad bit of understeer but not much if any at all.

I didn’t even realize who posted that. :joy: What kind of kart is it?

Which model?

Normally this where I’ll ask if you’re sitting the inside back down too soon causing it to over power the front. Could be because the kart itself doesn’t want to carry the inside or because it’s unloading too abruptly and causing you to unconsciously sit it back down with steering correction.

Welcome to kart tuning voodoo where everything does the one thing and the opposite thing at the same time that it also does something else… :joy: I think it annoys my friends that I can’t just say do this thing to fix it before I go deep diving into crazy chassis physics land.

2024 zenith chassis i was thinking of trying a stiffer axle?

I’m not familiar with what they normally run in those. Do you have a medium currently? You can always try cutting it down to 1000mm and running the same track width if you haven’t already.

currently running an n axle ive thought about cutting it short but would prefer not too.

I cut all my 206 50’s to 1000 before they ever get in the kart.

Looks like I’m getting the sawzall out then. I’m going to call it “The Matty Mod” :laughing:

This :point_up_2: right here. The more grip and taller you are the more and more important this is. Something we didn’t learn nearly soon enough in 206. In KA100 now, so not the same necessity.

You’d be surprised how much of a difference it actually makes. :grin:

@tjkoyen may back me up on that… Hopefully…

@CrocIndy Having a shorter axle should help the chassis bend even more when cornering right ? Shouldn’t you avoid that when you have more grip ?

In my experience, it frees the kart up and helps it get off the corners for whatever voodoo reason when compared to a longer axle at the same track width.

When you use hub spacers, you see where the anodizing wears off of them because of what I assume is hub flex so it’s not really having the chassis flex more, but the axle/hub connection. It seems to help us carry the unloaded chassis longer through the corner.

It should hep the center rotate a bit better right matt?

It should, yes. At least in axle voodoo theory, it should.

You don’t look too far off to me. If you are following the fastest guys they aren’t pulling away from you, however, the camera kart does seem to catch you on corner exits the first half of the race. I would think a small change or changes is all you need. Your line looks good but this track doesn’t appear to have many great passing areas, especially for 206. So is it all about qualifying? Experiment with every session looking for the right combination.

The shorter axle length setup at the same track width will allow the hub to flex more on the end of the axle because there is less engagement of the axle inside the hub. The axle actually becomes stiffer due to shorter length, but the hub to axle connection becomes more flexible.

In higher grip conditions our fastest LO206 drivers would actually use hard axle that was cut down to help “free” the kart on exit. It does not completely make sense to me, but I have seen it work on some of the highest grip in the country and at some large races in hot Texas summer.
