Black 39mm velocity stack for Honda CB500, CB550 & CB750. Check the fitment list below for details. Lightweight aluminum construction just like the original velocity stacks on vintage race bikes from the 60's. Has a concealed micro mesh screen filter backed with a larger mesh to keep it in place at the base of the velocity stack. Will not hit the frame on CB500, CB550 & CB750. All other models check dimensions before purchase.
Sold Individually. Includes mounting clamp. Clamps are painted back and tend to chip. Can be touched up easily with spray paint if necessary.
NOTE: Velocity stacks let more air into the carburetors. You will need to install larger jets and or make other adjustments to the carburetors.
NOTE: Be sure to measure your carburetor prior to purchase. Also measure how much room you have between the carburetor and the frame or any side covers. Use the dimensions below to see if these will work on your bike. Just because the filters fit the carbs doesn't mean they'll fit in the bike without some obstruction.
NOTE: Velocity stacks are not CNC aluminum. They are stamped aluminum.
