There have been a lot of posts about EFI 2 strokes. This one is nor DFI but simply EFI and it runs well and gets great mileage. though some of you might be interested. Guy seems to know what he is doing. http://twostrokemotocross.com/forum/general-two-stroke-talk/yz-250-efi/
Theres a 500cc FI too http://twostrokemotocross.com/forum...zr-500cc-fuel-injected-2-stroke-finally-here/
Yeah I guess that one has some issue due to the injector being behind the reeds instead of in the transfers like the YZ250 one.
Pretty cool but the way he describes the power sounds like what we have experiance with the metering rod carb for a lot less money and effort.
