I think more important things include, keeping your suspension free and clean, make sure all the pivot balls on the turnbuckles move freely. Make sure none of the arms or shock mounts stick. Make sure the steering is totally free. Learn how to enter and exit a corner without blowing past it. Learn jump rhythm, learn how to correctly set your drag brake, learn how to mount tires straight on the rims and balance them. All that little stuff makes a big difference. I will even remove all of the seals from the bearings in my transmission, except for the 3 that are exposed to the outside elements. The two outdrive bearings and the one the slipper shaft exits from.
