Yamaha - Carburetor Assembly 4 - Fuel System Component - 62Y-14904-42-00

Overview

When one carb in a multi-carb setup starts falling off, the whole engine feels out of sync. I’ve worked on plenty of Yamahas where one weak carb caused rough running across the board. Swapping in a fresh unit like this brings everything back into balance. Once it’s right, the motor idles clean, responds better, and just feels stronger across the throttle.
