Hello ,,,I got an old Margay kart and was wondering what some good percentages would be to scale this kart out?
So far I do know what my total weight is-225..
I plan on using Sideways bathroom scales setup method, It sounds good,inexpensive way to scale out a kart.

been racing forever, i run a 2001 olimpic so my set up my be a little different but i run 53-57 on cross(lr-rf) 52-53 (left side)and
50-52 nose. also if not already use maxxis
ht-3's (rf and rr) hottest tires going. I don't know if your rf spindle will allow for it but use 8.00 or 8.10's (can't remember number. On left front 4.50 hg-3's, on left rear 5.50 hg-3. rr stagger 5/8 to 3/4. rf stagger 1 to 1 1/4.

I would also get the rear percent to around 54-57%.But the stagger is right.I disagree with the Maxxis.I like burris tryed alot went back to Burris every time. just my two old green pennies worth.We used 6.00 lr,7.10rf,8.10rr and 5.00lf dxb compound and if hard and slick DXA.Run low air 5lf,7-8rf,5-7lrand6-8rr.

You are counting your total weight with you in the kart, fully equipped and seated like you are racing, right? 225 seems a little low, our light class has a minimum of 315. I don't think too highly of the Burris tires, Maxxis, Dunlops, and Firestones have all done me well on dirt and asphalt.

Yes 225 is the total weight. It is with my 7 yr. old son, The track we are planning to run at currently has no weight limit. I look for this to change.
What do you think about my percentages, what should they be?
I am just starting at this Kart racing. Been running stock cars for a while, but still never had one scaled. While just running the stock class never really needed to, was always competitive, but I know it would have had to help.
I guess you can say I want to have my son set up the best I can possibly get for him.

Oh, I thought you were running Sr. classes. For percentages, 48% nose seems to be a good place to start, and about 54% on cross. Play around with the seat mounts and tire pressures to adjust. You could also try asking this question on, they helped me out A LOT when I first started.
