Product Overview
A TT-R125 that has sat with stale fuel may develop plugged jets, a stuck float, dried seals, and a petcock that leaks or will not flow. This kit replaces both the carburetor and tank valve so the main fuel-delivery pieces can be refreshed together.
Installation still requires clean fuel, correct cable adjustment, leak checks, and final idle/mixture tuning. Valve clearance, compression, spark, intake leaks, and tank contamination can cause similar running problems.

Q: Is it ready with no adjustment? A: Final idle, mixture, float verification, and cable setup may still be needed for the bike.
