* Cylinder head: The cylinder head can be machined to increase the compression ratio and improve performance.
* Porting: The ports in the cylinder head and cylinder can be modified to improve airflow and increase power.
* Piston: A high-compression piston can be used to increase the compression ratio and improve performance.
* Cam timing: The camshaft can be modified to advance or retard the valve timing and improve performance.
* Exhaust system: An aftermarket exhaust system can help improve airflow and increase power.
Suspension tuning
* Front forks: The front forks can be adjusted for preload, rebound damping, and compression damping.
* Rear shock: The rear shock can be adjusted for preload, rebound damping, and compression damping.
* Ride height: The ride height of the bike can be adjusted by changing the length of the front forks and the rear shock.
* Tire pressure: The tire pressure can be adjusted to affect the handling of the bike.
Jetting
* Main jet: The main jet controls the fuel mixture at high throttle settings.
* Pilot jet: The pilot jet controls the fuel mixture at low throttle settings.
* Needle: The needle controls the fuel mixture at mid-throttle settings.
Test and adjust
Once you have made some modifications to your bike, it's important to test it and make sure that the changes have improved the performance. You should do this by riding the bike in a variety of conditions and making adjustments as needed.
