My go-karts steering will jerk to the right when i go over bumps, Why?

All i did was grease everything with some WD-40, and when i drive and hit bumps, it jerks to the right. Could it be the shocks? i didnt grease the shocks but could it be that since a greased everything the shocks are more sensitive to everything? I havent run into anything, so nothing should be off.|||Could be a shock failure, if the WD40 has eaten the seal then this could be a problem





Do you have adjustable shocks? Try adjusting and test at slow speed to see if that helps





Are your ball joints worn? WD 40 will dissolve grease in ball joints





IF someone has the same kart shocks, see if trying those solves the problem.





Maybe your tyres are incorrect pressure or you have tyre wear due to that 180 turn which may have put something out of alignment causing bad tyre alignment?|||There may be nothing wrong mechanicly with the steering, it could just be "Bump steer' which is associated with front end design.|||Look at the steering linkage; the left side should be the same height (from the ground) as the right. If they are different they will move differently as well. Your friend probably bent something that can be bent back.|||typically when you hit a bump on anything with wheels and i motor the wheel turns hold the steering tighter and see it it does it again
