Step 3: Connecting synchroniser vacuum tubes. It is composed by a FKI10531 N-MOS Power Mosfet, and a network of Zener Diodes (GDZJ24D) and resistors with the purpose of limiting the injector voltage at the time when the transistor opens (injector closes). Your DIY ECU unit is the solution. Step 2: Another fuel injection system, installed without air filter. Your email address will not be published. Due to environmental issues, HONDA BRAZIL has leaned to much the air-fuel mixture, which causes high temperature in the cylinder head and consequently cracks in the head. AFFORDABLE FUEL INJECTION FOR SMALL ENGINES NanoEFI is currently under development to bring low-cost EFI to powersports riders of all types. Required fields are marked *. All electronic fuel injection systems work in essentially the same way; information about the engines operating state is conveyed to the computer via sensors. Thank you for the time and effort spent in developing this elegant solution and also for generously sharing your work. 400cc to 800cc Small Engine Fuel Injection Kit Small engine fuel injection kits for 400cc to 800cc Engines with 1 or 2 cylinders, including 650cc engines. All prices are exclusive of statutory VAT and, Adjusting your motorbike's fuel injection system, Adjusting your fuel injection system now let's get started, 05 Tank must be secured to prevent it slipping. We have 42mm throttle bodies, 38mm throttle bodies, 34mm throttle bodies. Also have you had any bad reading with the system? You should find an optimum value (which depends on the speed and throttle) that lets you achieve a mixture which should be slightly "fat" (more gasoline than air). In addition, on our demonstration bike, the airbox must be removed to get at the fuel injection system. It might flush out some loose dirt and grime but, thats about all. 1: Adjust the needle damping. SE-EFI is an Electronic Fuel Injection conversion kit for small engines.
