Compatible Models

Product Overview
A cracked intake boot can create a lean condition that no amount of carburetor adjustment will fix. On a 1999 Big Bear, hard starting, hanging idle, bogging, or fuel leakage may come from the carburetor, the manifold joint, or both—which is why replacing them together can make sense.
The set targets 1999 YFM350 Big Bear applications and cross-references common Yamaha carburetor and joint numbers. California and 49-state carburetor specifications can differ, so compare the original stamping, jetting, boot angle, cable top, and airbox connection.
