Differences between Carburated and FI...
Ok, so i was just curious to know what are the differences and why do i hear people saying carbureted motors are more user-friendly than fuel injected. Can anyone with experience with the two please explain the differences to me? I have an 01 R1 thats carbureted and the only thing i notice about it that i wish i could change is the fact of it being a real pain to start when its cold - having to choke the hell out of it to get it started...lol. Other than that, i love it to death.
And what about using race gas with carbureted and fuel injected - i hear its better for carbureted and bad for fuel injection.

Re: Differences between Carburated and FI...
fuel injected bikes are easier to start, and run better in cold weather or changing altitudes... as far as being more user friendly, the throttle response is better on carburated bikes, more immediate and smoother when you get on the gas, the fact that newer bikes are run alot leaner and i guess just the nature of a electronic fuel system means there is a slight delay when you open the gas or sometimes its a little jerky
as far as race gas its not worth running in either, sometimes at track days if i would run out of fuel or forget to bring some i'd buy race gas and it never caused me any problems but its not going to give you any benefit

I have a Carburated bike, and its alittle harder to start as opposed to your EFI bikes, but to me throttle response is quicker in a Carburated bike. Like when its realy cold, i have to choke my bike so it will warm up but besides that it runs GREAT

Re: Differences between Carburated and FI...
there are ways of tuning a FI bike so that it's not so jerky though. usually richening up the bottom end of the fuel curve helps out alot.
beyond that, i think de la sol pretty much summed it up.

Re: Differences between Carburated and FI...
FI is usually "snatchy" compared to carbed. you don't do anything but stunt, so that's probably better for you, but for the racer, that jerkiness can upset the chassis and makes riding faster more difficult, and/or cause a crash. carbed bikes have a bit of a "buffer" that makes throttle transitions smoother.

Re: Differences between Carburated and FI...
Well...for the hell of it, i just went ahead and dumped practically a full tank of race fuel in my bike after running it for about 30 miles on the fuel light. I did notice that start-up was easy as hell even with it being as cold as its been. Typically, its having me out there juggling the choke around for a second, not trying to rev it up to 5 grand holding, and keeping it alive, but the 109 almost didnt require a choked start-up.....
that and it smells funky...lol
