Thats funny! Do you guys remember when EFI started to appear on automobiles? I dont recall any performance benefit. They may have started easier in the winter. I expect the same to hold true on the motorcycles.I do. There were exceptions, of course, but for the most part, EFI was a tremendous boon to automotive performance. The first fuel injection I remember was the Rochester FI units on Corvettes and other Chevrolets. They were all about performance, but they weren't electronic. Later, partially electronic Bosch systems started showing up on Euro cars, and while these seem crude now, they worked very well. They allowed the car to conform to emissions requirements with fewer driveability and reliability issues than with carbs, and generally improved performance. Some of the early attempts at EFI by US manufacturers, well, frankly, sucked because like so much else of the way the US auto industry dealt with emissions restrictions in the early eighties, they were half-hearted attempts to get around the regulations and avoid buckling up and doing something really right, at least on Ford and GM's part. The throttle body injection systems tried early on were abysmal. Chrysler just didn't have the money to do anything better than they did, but in several cases, their stuff, based on licensed Bosch systems, was the best of the time. The 4.0L Jeep inline 6 ran a lot better than any previous US engine of it's type ever did with a carb. But by the mid nineties, GM's port fuel injection systems, introduced 10 years earlier, had become very advanced, sophisticated and effective fuel systems that delivered excellent performance, driveability, and reliability from a car whose tail pipe emissions were required to be cleaner than the air going into the engine. Nothing remotely resembling the ZO6 Corvette (7.0L, 505hp, 22mpg) would be possible without it. Any motorcycle adopting EFI at this point in time is simply not going to have to travel the same long development path that the automotive world had to. That's been done already. All they have to do is to apply what's already known.
