Bikers Choice Keihin CV Low Speed .40MM Jets 5 Pk

These .40MM low-speed jets from Bikers Choice are specifically sized for accurate tuning of Keihin CV carburetors. When you're working on a modified Harley-Davidson engine, getting the air/fuel mixture just right is key to smooth performance, and these jets help you achieve that precision.

If you've recently upgraded your exhaust, intake, or made other engine modifications, you'll likely need to adjust your carburetor's fuel delivery. These jets are ideal for dialing in that performance, ensuring your engine runs efficiently and responds crisply to throttle inputs. They come in a convenient 5-pack, which is great if you have a multi-carb setup or want to keep spares on hand for future adjustments.
