I'd say no one will give a toss once they ride them... manufacturers will be more concerned with developing their new 350's than FI....

Alot of the jap guys running FI went back to carby didnt they ? (didnt like the hitless curve)

OT: heard any more news on the 350's disco? Coming from a 400 it would be my dream bike. There is just too big a jump from 250-450 at the moment.

Good point Disco... i think a 350 will be awesome... but i also think you will be able to ride them faster than a 450 around most tracks IF there light like a 250.
I think FI is aimed for the average rider... or the rider who loves the hit like a 2 stroke...

Don't know why they would, you can program any map into it, including a power hit.

I don't think so. Besides, housing has doubled in the last few years and dirtbikes havent gone up at all. Relatively bikes are getting cheaper and cheaper. A bit like PC's. I only paid $8500 for my KTM. I paid $10500 for my YZ in 2002.

Don't know. I don't think they can replicate the carby system 100% though. Sudden open throttle situations there is some sort of delay or more mild power onset with the FI systems from memory ?

You can get MORE responsive power from fuel injection than you could ever get with a carby.
The Carby you have to rely on vacuum to suck fuel, where as fuel injection is pressure fed into intake. Although you have accel. circuit to pump. It is not as accurate.
I don't know why you would also want to replicate a carby!!!!!!
People need to ride a fuel injected bike first then decide.

I remember when the first Honda SP2's came out(Or was it SP1)
The fuel injection was too much hit when rolling on throttle, abrupt even was a lot of peoples comments.
