Re: Need some setup help?

What kart and year... I'm sure someone will help you after that but from what I just read and making a guess if it is good in the first half and gives up in the second half of the race it is probably a tire issue!!

Reduce Left
Reduce Cross
Add 1/4" rear Stagger
A Harder Left rear Will Help As Well.

Re: Need some setup help?

Sorry just getting a grasp on setup. What is the best way to reduce left. And what does adding the rear stagger do?
Thanks for the information

Re: Need some setup help?

Move your seat and/or butt more to the right to reduce left. rear stagger makes it turn better in the corner but takes away from straightaway speed. being a older kart I might assume that its a low cross kart?,,, meaning that if you raise the cross it will tighten the kart. i know it isnt the same but, i had a 99 coyote that i ran at 52 cross and it got tight around 57. IMO

Get ahold of Dan at Dixie karting he will tell you what the kart needs.
More rear stagger helps the kart rotate thru the corner, what you gain overcomes what tiny bit you'll lose down the straight

Re: Need some setup help?

If the kart is entering the corner and just is a push off leave it and add more rear stagger this rotates the rear end around the corner better helps your turn a tighter radius, rear stagger mostly effects the kart center off.

Don't make all kinds of changes if you only have one issue.

This Probe was a wicked kart when you nailed the setup and believe it or not we used high cross in the 90's

Re: Need some setup help?

I'd take some cross out of the kart (high 50's to low 60's maybe) and I'd add some rear stagger (to 1").

Re: Need some setup help?

Works good for several laps, then goes away. Indicative of too much cross. Overworking RF past the point where the tire overheats and gives up.

Re: Need some setup help?

We ran probe back then. No more than 44 nose. Do not change the other.

We ran that much cross on them. Get some nose off that will make the older karts push from the middle out.

I still think it may be tires. If its good then goes pushy then your too aggressive on bite.
