Black 39mm velocity stack for Honda Kawasaki and Suzuki models listed. 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.Dimensions:39mm ID where it mounts to the carburetors63mm total length60mm outer diameterFits Honda:CB500K - 1971-1973CB550F Super Sport - 1975-1977CB550K - 1974-1978CB750A Automatic - 1976CB750F Super Sport - 1975-1976CB750K - 1969-1976Fits Kawasaki:KZ400A Deluxe - 1977-1978KZ550A - 1980-1983KZ550C LTD - 1980-1983KZ550D/H GPZ - 1981-1983KZ650B/F - 1977-1980Fits Suzuki:GS550 - 1977-1979GS550E - 1977-1979GS550L - 1979NOTE: Fits other model bikes as well.
