Will I need to rejet my carburetor after installing this filter?

K&N claims that generally no jet changes are required when using their filter element. However, you may need to make adjustments based on your specific riding conditions and altitude.

How often should I clean and re-oil my K&N air filter?

The cleaning interval depends on your riding conditions. Inspect the filter regularly, and clean and re-oil it when you notice a buildup of dirt and debris. K&N sells filter cleaning and oiling kits.

What kind of oil should I use on my K&N air filter?

Use only K&N air filter oil, or another oil specifically designed for oiled-cotton air filters. Standard motor oil will clog the filter.
