Need a little help

My sons kart is pretty fast but he's a little tight coming out of the corner and seems to get worse the longer the race, can I move lead or add rear stagger to help this?
 
It would help if you posted what kind of kart it is, and your current set up info, as well as what tires you use, and what track you are racing at..then someone may be able to give you some advise.
 
Well I have a helix and my setup might sound foolish but every setup people give me doesn't work and the kart hops like crazy, it's a small track with very little bank, I have nose 47 left 62 cross 69 11/2 front stagger and 13/8 rear lf camber 1 rf camber 2.5 i run vega tires yellows on the front and white on the rear it's the only setup that has worked, the track is also pavement

way too much rear stagger for pavement IMO
And the cross is way high, and also LS is too high.
What baseline did you start with?
Are you running a 5 deg. LF spindle setup?
 
Also with your current set, you are pinning the LR and overworking the RF causing your problem
 
Depending on size that stagger is okay, I'd get on yellow Vegas all the way around thins on the left. More rf camber also. I would lower all your numbers, 46 nose 58 left 62 cross and try that as well as what Jamie said using the 5* spindle
 
Not that I really know a lot about it but I've never seen a setup with such a high LR percentage. On average, and I check a lot of them, the LR Carries about twice the weight of the RR, +/- 20%, but you're carrying almost three times the weight. In fact you're LR percentage, compared to the RR, sets a new record!
How come nobody ever tells what the turn radius is? Knowing that might help determine if the stagger is right or wrong.
One other thing, your LF is at 20% and the RR is at 11%. I've heard several people say those percentages, if not the same, should be pretty close, but I don't know if that has anything to do with your problem.
Comments compliments criticisms and question always welcome.
If the data does not support the theory, get a new theory.
 
Al its not uncommon to run high LS % some on syrup are higher than that, maybe buy you a dirt oval kart and experiment, and quit theories

I welcomed criticism, just like it says in my SIG. It’s just that you’re criticism is directed at something I didn’t say. Point to where I said anything about the left side percentage.
And I ask you; what theories are you speaking of? There was not one theory in my post.
Now I understand it’s a possibility you may not be real clear on what a theory is, but if that’s not the case, forgot I said this.

LR % is based on LS and Cross, so yeah you did mention it.
Check some setups for syrup or rosin

A theory is just an Idea

You used your idea to come up with the answer above, we dont really care what % each tire carries as long as cross, nose, and LS % are correct
 
Your baseline numbers look average for pavement. Your cambers are off though....drop your LF camber to 0.5 positive, and up the RF to 3.25 negative.

I would agree JP if it were a normal kart, the Helix isnt normal, in fact its beyond normal
 
Having worked with a few Helix's on pavement, It's not outside of normal even for a Helix on pavement.

What kind of castor are you running?
 
6/8-10 is what most ive seen are running, so they've been running less than factory
Also the champs seem to be more inline with other karts.
Also the newer Helix's that have the 7.5/15 deg spindle setup seem to be closer to normal pavement setups
It seemed the 10/10 deg karts were kind of odd ball to get to work, wasnt a whole lot different than a high bite dirt set up
 
LR % is based on LS and Cross, so yeah you did mention it.

So you did get it wrong. LR %, when comparing it to the RR, has nothing to do with the LS % or the cross. The LR weight is part of the LS %, we all understand that.

There were no “ideas” in my post. Just stating the facts.

You used your idea to come up with the answer above, we dont really care what % each tire carries as long as cross, nose, and LS % are correct
I used my spreadsheet and reported the facts. I may have some ideas, but without experience, I keep them to myself.
Front and rear cross are not used, I understand that, but they are there and so I report them. LF to RR cross percentages are seldom used either, but there in my spreadsheet so I report them.

So you used your IDEA? not one that all oval karts uses did you not?
Here's my THEORY Al, buy an oval chassis and get a clue
 
Throughout history, it’s amazing how many ideas have been scoffed at until the person with the idea, or someone, showed it to be true. Many of Einstein’s theories and ideas were scoffed at. And the scoffing came from some of the smartest people in the world. Not that I put myself in that class of ideas, but the parallel is similar.
Whenever I am given an idea, I try to test it and see if it has any merit. I found very early in my karting career that I wasn’t too good at proving whether an idea was good or bad just thinking about it.

No I didn't use my "ideas", I stated some facts.
The fact that nobody understands front and rear cross bothers me not, because it's there.
And you can't insult me. And the fact that you keep trying only puts you in a bad light.
You can always tell when the other person has lost the argument. They start cursing you and insulting you.

Al you lose every oval argument, i havent lost I just dont give a care what you say, you have ZERO experience in dirt oval and it show's
No body cares about front and rear cross, you should take the hint, Nose% LS% and Cross% is all we care about in oval racing so get over trying to push your lonely way of thinking on people, buy an oval kart, hit the track and get some real world experience in dirt oval karting or you'll never understand, or your just to bull headed to care
Everyone is wrong and your right
