Where can i find the carb casting #?
« on: August 22, 2008, 03:03:29 PM »
Hello Everyone,
I was trying to figure out what size the main jets come stock with my keihin carbs. i have a 1974 Honda CB750 K model. i saw a chart where they stated that they came with size 120 on the mains. but then i found another chart that said depending on the casting number it will give you different sizes...i think i saw some that said they were equiped as low as 105. where can i find the casting number? thanks

The carb number is stamped into a boss on the engine-side of the carb, top side if I remember correctly, near where the carb bolts to the mounting plate.
