About the Yamaha YZ450F
Match the carburetor section and the fitted fork generation.
A carburetor mid-body leak, a damaged intake holder and a leaking fork need three different repairs. The YZ450F parts here cover selected years for each assembly: mid-body service for 2003–2009, holders for 2006–2009, and separate fork-seal groups. Preserve the 2006 SPV holder entry when that designation applies.
Identify the leaking carburetor joint first
The mid-body kit with screws services a particular carburetor joint. It is not evidence that every jet, float-valve component or intake holder is supplied. The holder is a separate connection to the engine, with YZ450F 2006–2009 and YZ450FSPV 2006 entries that should remain distinct.
