An evolution of the popular Mikuni TMX model, the Mikuni TMS38 Carburetor offers vastly impored mid-range and top-end performance with precise jetability. Design changes include a TMS flatslide throttle with no cutaway. Instead the slide has a specially designed internal chamber with two metering orifices. There is no screw-in pilot jet, and the pilot fuel is now metered by the jet needle. Tuning is quicker and more simplified with less components.
The installation of an optional speical jet needle (the Pro Option Needle Kit) in the TMS allows the main jet to be removed for even further performance. This special jet needle meters more fuel near the top of the needle jet where a substantial quantitiy of fuel is available. This allows the air/fuel mixture to be more consistent, resulting in a even more noticable perfromance increase.
Available as a complete kit, the 38mm Mikuni TMS Carburetor is inteneded for use in off-road racing applications on 125cc, 250cc, and two-stroke engines. Kit includes carb, throttle cable, airboot adapter, main jets, jet needles, hose, clamps, pocket tuner and instructions. The TMS Carburetor reaches new heights in predictable power. By designing a needle jet system (without pilot jet) to control all fuel delivery, we achieve smooth, instant transition from idle to WOT.
The TMS is no longer available but some parts are in limited quantities. |
