All Balls Racing – Carburetor Rebuild Kits - Kawasaki, including kits for the 95-05 Vulcan VN800A, the 87-06 VN750 Vulcan, the 90-96 EN500 Vulcan, the 88-07 EX250 Ninja and the 87-09 EX500 Ninja. These are multi-carb street bikes, so each kit is packaged with the float needles, seats, bowl gaskets and o-rings needed to bring every bore back to the same spec rather than leaving one lazy carb to spoil the set. Age is the enemy here: the rubber tips on old needles take a groove and let fuel past, hardened bowl gaskets weep, and a partly blocked seat drops the level enough to make a twin surge on a steady highway throttle. Rebuilding the whole rack evens out mixture across cylinders, removes the flat spot at the transition, keeps overflow fuel out of the airbox, and lets you sync the carbs to a stable idle that stays put. On a high-mileage Ninja that also ends the flooding that makes hot restarts a wrestling match. Label every jet and bowl as it comes off so nothing swaps bores. Tell us the year and exact model and we will confirm the right Kawasaki carburetor rebuild kit and quantity for your multi-carb setup before you order.
