Xbird said it over steers or pushes in a turn.Thats what ive been saying,the swing aarm acts as anti role in back witch makes the front bite and it still over steers.Thanks Chuck!
Ok aarm building 101,square tube is the easy way.
No need for a jig your only building 2 each.
#1.draw the arm on a table or floor the right size for the mounting points on frame and how long it should be.
#2.Cut tube to the line and put it on top of the line.
#3.When you have all the tubes cut and put on all the lines tack.
#4.Cut more tub same as in step #1 put this on top of the 1st aarm to use for a jig and repeat.
Every keeps saying tools I only had a welder and grinder I cut every tube and saddled every tube with a grinder.Then skill like ive said before I had never done this before and it dident over steer by the way.So I looked at bmi karts and it looks like it would cost $280 for 4 aarms ans 2 spindles.
Now 1'' .095 wall tube is $1.38 a foot bmi said the yd arms are about 15'' so 10' of tube is under $13.80.for the spindle get 2 foot square and 2 foot of flat bar,that should be under $10 also.It looks like for you can build it for half price.
