Vortex 10 Map ECU
The Tokyomods ECU by Votrex is like our CDI and EFI Interceptor rolled into one module. It controls not only Spark timing and Voltage output but also Fuel Metering and other engine management functions. The result is more power, better power, easier stating and ultimately faster lap times. This unit comes pre-programmed with 10 Performance Fuel & Spark timing maps as well as having 3 additional switches for trimming fuel in Lo, Mid and Hi throttle openings. The ECU plugs directly into the bikes standard wiring harness and has all necessary mounting hardware supplied. Performance gains vary depending on throttle and RPM points however typically a gain in top end power and bottom end throttle response is expected from the "Power" settings and a smoother more tractable or ride-able power from a "Traction" setting. We have done extensive work to include tune parameters which improve starting and almost eliminate the flameout experienced with EFI MX bikes. We have done nearly all of the development work for you!  All that is left is for you to do is chose a setting that best suits your riding style or the conditions and ride!

Tokyomods Carburetor Mod
Tokyomods is the originator of four stroke carburetor modifications .The Tokyomods Carb Mod will dramatically improve the performance of your four stroke motocross or off-road machine. We start by completely disassembling and cleaning your entire carburetor, along with inspecting and replacing all damaged or worn parts. The process continues with modifying and installing the Tokyomods jetting specs together with any accessories that the customer requests. Lastly, every unit is bench tested before it’s packaged and shipped out to the customer. The majority of carburetors that Tokyomods modifies have some sort of other pre existing problem; this is why we won’t just sell a "jet kit", Jet kits alone are not enough to keep today’s complex carburetors performing at their best.
