Harley Fuel Injectors
Fuel Injection Calculators: Pressure / Volume / Horsepower
Harley OEM and RB Racing Fuel Injectors
2006 models are 3.91 grams/second. 2005 and earlier are 4.35 grams/second. The 25 degree CVO injectors are rated at 4.89 grams/second. 5.5 grams/second Screaming Eagle injectors are available from Harley-Davidson. Harley Davidson has a service bulletin on injector swaps for earlier models.
Keep in mind that an injector will never flow what it is rated statically. Injector duty cycles should not exceed 85% at peak horsepower.
