motorcycle EFI

[George Gorman]

Hello everyone,

Have been lurking for a while...hello to the guys at orbital and soanar

Can anyone tell me why large capacity 4 cylinder 4 stroke motorbikes (eg
ZX9)are carby (excepting the 1999 GSXR750) while large twins (eg ducati
TL1000) tend to be EFI?

Are there any advantages to changing the carb setup on my 1988 GSXR 750 to
EFI? 

And a dumb question - how many times per engine revolution does an injector
fire? If it's only once, wouldn't you get a non homogenous mixture in your
cylinder? Or do you get good mixing /atomisation from the compression at TDC?
