No kidding! Haha. I honestly didn’t know that was a thing. My only experience is with cars, and those are already designed the correct way. I learned something this week. Needless to say, I have a few master cylinders for future projects.Sometimes calipers need a "This side up" casted on to them.
Thank you! That helps big time. Steering geometry was a big hurdle on this kart.Sounds like you may need a bit more caster in your suspension. You usually want about 5⁰ positive caster, so the kingpin of the steering spindle should be leaning towards the rear. With that, your steering should go back to center with less effort.
Bump steer is all about the angle of tie rods. This may help.
