Using your AS3 Performance Factory Series clutch assembly is a breeze. First, make sure it's properly installed on your off - road motorcycle. The 'Quick Adjust' wheel is located on the assembly. To adjust the clutch responsiveness, just turn this wheel while you're riding. You can also adjust the reach setting according to your comfort. When it comes to the protective rubber boots, they are there to keep dirt and debris away, so don't remove them. As for maintenance, regularly check the pivot area for any signs of wear or damage. Clean the clutch lever with a mild cleaner, and make sure the plastic insert rotates smoothly on the bars. If you notice any issues, contact our support team. Remember, this product comes with a 12 - month warranty, so you're covered for any manufacturing defects.
