Hi Jayson,

I'm not sure exactly what kart you are talking about, but I suspect it was 
the racing kart at: 

I got a racing kart cheap, however the chassis was in bad shape, and the 
engine was broken. I decided to weld up the chassis frame and to add a 
motorbike engine. However when I welded the frame it became too stiff and 
did not flex at all. I tried adding front (heavy) bumpers to the front to 
add extra weight, but it still didn't handle great.

In the end I made a new lighter and more flexible chassis. With a kart 
frame as there is no suspension, and as there is a solid live rear axle 
(where both wheels spin together), in order to go around a corner the 
inside rear wheel must slip to allow the outside wheel go faster. For this 
to happen the chassis needs to flex.

Best of luck,
