Ceramic cylinders dissipate heat more efficiently to keep engine temps down. A must have for these KLX140s

Notes:
Re-jetting of the carb is needed after installing this kit. We strongly suggest an aftermarket exhaust with any bore kit. We recommend using a high octane race fuel with anything above 13:1 CR.
