Carburetor for Yamaha TTR 90 & TTR90E (2000–2005) | OEM 5HN-14101-10-00

Product Overview

Replace a worn, clogged, leaking, or poorly performing carburetor with this replacement carburetor, designed for select Yamaha TTR90 and TTR90E dirt bikes using OEM reference numbers 5HN-14101-00-00 and 5HN-14101-10-00.

The carburetor controls the air and fuel mixture entering the engine. A properly working carburetor can help improve starting, idle stability, throttle response, fuel delivery, and acceleration. If your Yamaha TTR90 has hard starting, rough idle, fuel leakage, hesitation, poor throttle response, or unstable running, replacing the carburetor may help restore smoother engine performance.

This carburetor features a 19mm manifold intake diameter and a 35mm air filter outside diameter. Please compare your original carburetor’s OEM number, intake size, air filter connection, choke setup, throttle cable connection, fuel inlet position, and overall shape before ordering.
