Carburetor Main Jets

12 products

Our Carburetor Main Jets for Harley-Davidson selection covers the single most common tuning change on any carburetted V-twin — swapping main jets to suit altitude, intake, exhaust or climate. Iron Stable, run by Iron City Motorcycles as an authorised Harley-Davidson dealer in Leeds, keeps a broad inventory of main jets for the Keihin CV and S&S Super E/G carburettors fitted across Harley-Davidson Big Twin, Evolution, Sportster and Twin Cam platforms. Leading names in the range include EBC and S&S Cycle, giving you a wide spread of sizes so you can dial in mixture precisely rather than settle for "close enough". Whether you are re-jetting after fitting a new air cleaner and exhaust, or chasing the perfect plug colour on a fresh Harley-Davidson build, we stock the jets to make it possible. Our team is happy to advise on sizing. Browse the full range below.
