400cc --800cc EFI Kits
Compared to other Small Engine EFI kits of us, this is a comparatively "large" engine EFI kit. It is designed to convert some carburetor engines of 400cc to 800cc range. Because of larger displacements, everything (almost) needs to be larger size; namely larger fuel pump, larger fuel injector; etc. Besides, this 38mm throttle body comes with an idle control motor built-in. This kit makes it easier for those who still own a carburetor engine in the 400cc to 800cc range, and want to convert it to fuel injected. Same as other kits of ours, this one is easy to install and tune. The key is to make sure your carburetor can be replaced by the 38mm throttle body. Or you may need to machine a spacer. This kit has all the features of the smaller EFI kits, like self-tuning capability. This kit by default will run 1-cylinder engine. For 2-cylinder engines, like V-twin, or parallel twins, more modifications are required, in many cases, a new manifold or new throttle body set will be required. contact us for details.
