Carburetor Mod / Complete Carburetors
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.
