About 40mm Mikuni Carb
A modification or restoration on your motorcycle would not be complete without a quality carburetor upgrade like the 40mm Mikuni carb. Whether you cruise the streets on a Harley or travel the beaten path on a Honda dirt bike, Mikuni's reputation ensures sound performance. Unlike the butterfly throttle valves used by competitors, which can obstruct the air flow at throttle openings, Mikuni carburetors feature roller bearing throttle slides that reduce airflow obstruction. This allows more air into the engine for faster response at different throttle settings and better overall performance. The Mikuni carb bolt-on kits come with all hardware included, making installation easier because you can pull the carb out of its package and bolt it directly onto the bike's manifold and head. The vast selection of carburetors in the large inventory on eBay not only includes the 40mm version, but sizes ranging from the 32mm Mikuni carb to the 38 Mikuni carb, so you can find the right size carburetor for your bike. The inventory also includes Mikuni rubber flanges that fit 32mm through 40mm Mikuni carb sizes, as well as intake manifold car boots and clamps in a range of sizes.
