UNIVERSAL VELOCITY STACKS     

MIKUNI KRS-004

These are measured for fitment by the mounting diameter on the carb,
not the carburetor bore or throat size.

these are 55mm mount diameter, and step down to 51mm throat/bore size.

SOLD EACH, 1 Stack per order,

 SORRY ABOUT THE PICS THAT SHOW 4 STACKS,

(That is how I get them, and I sell them individually)

YOU GET ONE PER ORDER.

(It is cheaper to buy per unit,

if you buy 4 at a time-see my other listing)

Velocity stacks improve the air flow into the carburetor, to increase induction efficiency, and increase horsepower on racing engines.

Particularly Helpful when removing the stock airbox  to create the vacuum necessary for good carb tuning and performance.

Shorter length stacks are going to be better suited for top end power, while longer will have better low RPM power.
