I do agree, and believe EFI is far superior, if, and only if, its got a feedback loop that will determine how rich/lean its running.. Magnelli systems on our old bikes do not have this, so they are not an ideal EFI system. With that being said, mine was running fine on the Ultra, till I got to dicking with it and decided to put a cam and bump the compression a bit.. Long story short, it was cheaper and more likely to get me where I wanted to go, to simply swap to a carb.. Had I decided to leave it alone, I'd have continued on with the MM EFI.. It did what it needed to for me, just didnt ever sound right, but it was good and reliable..

 

Ferrari use MM. Seems adequate! Jus sayin'.....

 

With no o2's??

 

well its like this the english like warm beer - because they own Lucas refrigerators

now what the Italians have MM as the injections system in enzos cars you know its not the same as harley bought from them

 

All I read was Ferrari look like I need to get this Ferrari harley now lmao

 

I wouldn't use MM EFI, I would switch to carby....Delphi is fine but the high idle gets on yer wick after a while.....

 

I dumped mine but only because I went to a 127ci . The M&M would not be able to keep up...
