Last year we featured a complete SU Eliminator II carburetor rebuild kit that was introduced by American Prime Manufacturing ( APM ) in California - " Back to the Future ", February 2022 /# 271 . Now , news comes to us from Ben Kudon that APM is offering a professional factory rebuild service - " to take your SU from comatose to like new !" For over 50 years , the SU carburetor in modified form , known as the SU Eliminator II , has been a ' go to ' for early American V-twin motorcycles . Ben Kudon says that " it provides smooth , even power and torque throughout the entire power band , with excellent
M-8 " Vanquish " Rocker Covers
Signal Hill , California based Ken ' s Factory is known for a design approach that " responsibly applies great detail and intricacy to elegant motorcycle components , resulting in next-level style for the American motorcycle ." Seen here , these " Vanquish " rocker covers for M-8 applications " hold true to our principles of seeing the design in the details and are one of our higher-selling SKU ' s globally ." This 6061-billet aluminum rocker cover kit fits 2017-up M-8 engines . Available in polished aluminum or its " Black Machine " black anodized treatment - with the raw aluminum machined to be exposed - they are designed to use the OEM gasket and are an easy stock rocker replacement . " Here at Ken ' s Factory , we are proud of the great reviews we get for our designs and service . We pay as much attention to
cold-start characteristics and drivability . " Although originally intended for aircraft and automobile use [ it was the stock carb on the most famous Jaguar models among others ], the SU carburetor has proven to be unmatched in performance when adapted for use on American V- twins such as Harley Knuckle , Pan and Shovelhead motorcycles . " The rebuild will be a complete teardown and deep cleaning using our ultrasonic cleaning technology . We will then reassemble your SU E2 , using all new parts where needed , including new seals and gaskets . We will install a new jet needle , main jet and piston return spring of your choice , as well as a new needle and seat . We can even add an extended float bowl kit ( by request ) for carbs that will be used on strokers or big bore motors . " Here is how it works : you send us your SU E2 free of gas and excess external grease / dirt via insured and prepaid UPS or USPS . It is extremely important to package the carburetor securely so that it will not incur damage in transit . Also , be sure to include in the package your complete contact information . It would be helpful to call us prior to start a work order . " Once the rebuild is complete , APM will return the newly rebuilt carb to the address the customer specifies prepaid ( applies only to continental U . S . addresses ) and insured via UPS or USPS . The rebuild work will be covered by a 30-day limited warranty only against defects in parts or labor performed . Incorrect tuning by the customer is not covered by warranty ." It became a ' go-to ' back-in-the-day because of the added potential it had over the entire rpm range where other carburetors failed to perform . The story of the SU is a part of V-twin industry lore - one that goes right back to 1908 , when George Skinner got a patent for a carb with a ' collapsible chamber ' and
consistently quick shipping as we do to manufacturing and stand behind our products with a full warranty . Our ' specialty shop ' approach to production yields shorter , higher quality artisan batches , so inventory is limited between runs ."
