One thing about the rear track width, with the wet rims, not being as wide. From 1400, I throw in a 20 or 25mm spacer on each side to make the wheels aligned with the bumper. It’s one of the two sizes, I can’t recall which one, but it works. With the spacer it still measures at 1400mm.
Hi Des - As a new kart dad, your videos have been the absolute best resource for me building and setting up my son’s kart. Great production value and the quality of instruction! Thanks for your great work! I see how easily the hubs move up and down the axles on your video. My son runs a Top Kart Kid Kart and the hubs are so tight against the axle that I can’t move them, even with the cap screws removed. Any tips? Thanks
Another great video Derek. Just wanted to add that when you might get this checked on race day in tech with tires mounted, it’s important to remember that it’s measured to the edge of the tires, which might be wider than the edge of the rims with no tires mounted and need to account for this difference. I make sure to measure with tires mounted so not to be DQed. Your thoughts?
I do the same tuning on all karts no matter the brand, with that said, there are some small unique things specific to a type of kart, but generally the same fundamentals apply to all karts
I'm from Brazil, I liked your video, mine is a thunder axle 40mm it's skidding from the rear in the curves a lot, it's all open 1400mm in front and behind what do I do to try to improve?
I'm 6.1' height, my kart sits flat, no inner rear wheel lift, and I feel corner exit understeer. 1370mm rear width. Caster neutral. ...Add Caster for front grip? Widen rear? Cheers!
@@PowerRepublic Hey! Actually 1360mm! 2 stroke, using Vega Blue Hard compound. Sadly My lack of experience keeps me from giving better feed back under braking, but nothing feels odd
@@Chris.J.A.B with the harder tyres we would generally use a smaller diameter axle or a softer 50mm axle. The Tony Kart 4SS kart comes with a 40mm for that reason I guess. Maybe soften the kart up to get it to 'flex' and lift the wheel when cornering if you haven't tried that already?
the thing that always bothered me about the spacers was that it effectively incresed the length of the axle, decreasing the ability of the hub to flex at the end of the axle?
@@PowerRepublic wow first of all i'm new to karting & learning heaps definitely appreciate all your videos. I just measured my sons junior OTK and its 1275mm. Next time out i will experiment more towards 1330. thanks
I race in Thailand and we using soft tires and hot asf. 😅 I'm using medium axle but by the final it's so sticky, if I put soft on it bends like twice before I get it to turn in so I should go medium hard right?
The top free agency WRs are too expensive. It is best to keep cycling them in through the draft from a cap situation. It really is like the RB position these days. The talent in college these days is just so damn good at the WR position. Teams that over pay there will feel the cap pain like teams with overpriced QBs.
Thanks for your help. 👍🏻👍🏻
No problem 👍
Hi Des can you go into detail about sort 50mm axles hard soft meduim and why and when you might use them ,and also large rear hubs .many thanks ricky
Yes I can Ricky, thanks heaps for tuning in and sharing the video

yeah boi, great tip, forgot to mention the wets. but yeah, definitely an easy job with the addition of a 20mm spacer
Topp👍 I always set maximum to 1398 to allow slight slippage and have a margin to 1400.

Thanks Dez! Could you do a same video with the front? Great stuff!
Hey Jordy. great idea, if you were brand new to karting it wouldn't be common knowledge. so yeah I reckon that's a great idea

agreed Jase, has to pass tech as you finished the race. 1400mm maximum so be carful. thanks for tuning in 😊
Thanks so much for these videos!
Thanks for tuning in Sammy
Thanks all. Liked and subscribed.
Awesome, thank you!
More Great content!! Thanks again!
all good chrsio, thanks for sharing the video
Good video, now need to follow up with a 'Driver tuning tips' version. Hehe.
Coming soon
All the info your giving is it specific to Tony kart or can I apply this info with my arrow kart

Move the rears to 1380mm. Maybe a softer axle and also too, do you have seat stays on or off ?
I'm 6.1' height, my kart sits flat, no inner rear wheel lift, and I feel corner exit understeer. 1370mm rear width. Caster neutral. ...Add Caster for front grip? Widen rear? Cheers!
yo Chris, what tyres you racing on? 1370mm is a little narrow for a 6'1 driver IMO. is the kart unstable under brakes?

@@PowerRepublic Thanks! I have been told to do one small thing to soften rear. Think I should try 1380mm or wider, up from 1360? I'm so curious!
the thing that always bothered me about the spacers was that it effectively incresed the length of the axle, decreasing the ability of the hub to flex at the end of the axle?
yeah that can be the case, and if you feel it, definitely use the rule measurement option. the spacers are there for convenience.
Hey, what’s a base starting width for OTK junior chassis with 30mm axels?
Thanks in advance
1330 ‘mm is the sweet spot IMO
@@PowerRepublic wow first of all i'm new to karting & learning heaps definitely appreciate all your videos. I just measured my sons junior OTK and its 1275mm. Next time out i will experiment more towards 1330. thanks
PR, where can I buy those spacers?
We sell them if you are here in Australia. Otherwise they are RR out of Italy 🇮🇹 so try Kartshop.com if in Europe
Is this the same for the kosmic chassis ? And what size rear hubs are you using
Yeah all karts are pretty similar in theory.
tony, kosmic, exprit, eos and new gillards all belong to otk group so the only difference between them is the color and stickerset
I race dirt oval, 12" or 304.8mm on the right and 11" or 279.4mm on the left rear, I can get the required 39.625" or 1006.475 mm for rtw. Any ideas?
Oh and btw, I noticed your very aggressive tow out settings on this kart as well. What a doozy... 🤣
🤭
I race in Thailand and we using soft tires and hot asf. 😅 I'm using medium axle but by the final it's so sticky, if I put soft on it bends like twice before I get it to turn in so I should go medium hard right?
Yeah grab a H and HD axle and try them out for sure
And maybe some short rear hubs
@@PowerRepublic will try this weekend thanks for your reply man
That seems like an easy job.
simple and effective Chriso
how much is this frame and plastic
Around 5000$ new and around 2000$ used after one season
