Suzuki carburetors were not jetted quite right from the factory, and over time, many of the flanges have become warped, causing slides to stick. The OKO kit includes the flange mount adapter, and the 26mm K-101 provides the RL 250 with quicker response and better over-all power. We also provide a simple airbox boot adapter that slips over the end of the stock airbox hose and onto the OKO intake.
