- Brand: Mikuni
- Compatibility: TMX35, TMX38, and TMS38 carburetors
- Usage: idle adjustment, maintenance, and original part replacement
A simple and targeted replacement part for riders concerned with maintaining healthy carburetion. Ideal when replacing components or during carburetor synchronization, this screw facilitates the fine adjustments necessary for a smooth idle. Installed in place of the original screw, it is part of routine maintenance operations on trail, enduro, or roadster motorcycles equipped with these carburetor bodies.
For optimal adjustment: start the engine, let it warm up, and make adjustments in small increments while monitoring the RPM and throttle response. If in doubt, have the carburetion checked by a qualified workshop to ensure the safety and reliability of your motorcycle.
