Idle Screws

Our Idle Screws for Harley-Davidson section covers replacement idle mixture and idle speed screws for 1981 to 1989 Big Twin and 1981 to 1987 XL Sportster models fitted with OEM Keihin butterfly or CV carburetors. Supplied through Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, the range supports carb rebuilds and tuning work on Evolution-era Harley-Davidson engines where a stripped or missing idle screw can make setting a smooth idle impossible. Parts come from CV Performance and MCS, both well-known in the Harley-Davidson carb community for fit and finish. Whether you are finishing a full carb overhaul or chasing a rough idle on a much-loved Evo, every idle screw here is selected for correct fit on genuine Harley-Davidson Keihin carbs.
