Jumpy physics

I’ve made a motorcycle out of physics constraints, it has a problem where the bike will jump occasionally, usually when turning. Turning up the physic stepping reduces it a little, but not nearly enough to solve the problem. From what I understand this is a common problem in games where the collision of something gets stuck inside another thing’s collision and the physic engine tries to separate them and they jump (is this correct?), however I haven’t found any ways to fix the problem.

I have a video showing the problem here.

I used add torque to steer and and angular drive to center the steering when the thumbstick is centered. This doesn’t seem like the ideal way to do it since it adds enough force to move the bike just by steering (shown in the second half of the video). If I recall correctly setting the rotation directly won’t play well with collision either.

Does anyone know some ways to reduce the jumpyiness or know of a better way to turn/steer the bike?
