If I add cross by moving lf won't that take weight off of left side? Jr1 kart having trouble keeping left side and nose weight up looking for 53% left and 47 % nose.

I have seat all the way forward. I will need to measure the right side. It may not be mounted right.

I don't know what the weight is for your class, but with 320 pounds, this is what the corners need to weigh to make the RR 45 pounds. Is this what you're looking for?

Weight minimum is 250. I'm at 259. Lf 50 rf 72 rr 52 lr 85 currently. Al have gotten your spreadsheet from you and I'm trying to use it for set up thank you. I just am having trouble making the right adjust to get me to the desired weights. I'm not by my kart or computer right now but will post the corner weights I'm looking for when I get to them.

09 ultramax element. Trying to set everything to Jr 1 guidelines in back of owners manual. Camber was at -2.75r and +.5l. Going to recheck again after adjustments.

You got good starting numbers now, don't sweat that RR weight being 2 lbs more than the LF, Run it and see what ya got, your time will be better spent on making sure the tires are right, even if you get the RR 5 lbs less for a Jr 1 driver your NEVER gonna know any difference than running it as is.
Once you run it, IF you have a handling issues it's NOT because the RR is 5lb heavier than the sheet your looking at, It' because other %ages need changed, or Tires are not right.
Good Luck !!

Agree
If you are hung up on those #'s try moving the RR wheel out or the LR wheel in . You might get the weight you want, but there are other, bigger things you are changing.

Thanks guys for the help and advice. Finally got it set up close to the starting numbers. Can be challenging to keep an eight year old in a seat when it's this hot and humid and when it's taking awhile because of my errors. I really appreciate the help and a great forum like this to gather and read information.
