The higher you jump, the greater the odds that something's gonna break. If your bike jumps have landing jumps....try to downside those when you're landing. Fladlanding is going to cause a lot of harm to all your stuff. Expecially the motor, every time your motor gets a jolt or gets tagged while it's running, it's sends an amperage spike hurting the comm and battery life.
Jump setups will need to be a little different than a normal setup.
Heavier oil, heavier springs, smaller pistons, looser slipper clutch to ablorb the impact on your transmission.
Try some of these things next time you go out jumping.
