Re: fuel injection not likely

just goin by memory here, but i was running some numbers way back in high school one day on a KX250, and i belive that at 10000 rpm the piston was going up and down 166 times a second.

thats 166 required squirts of fuel per second..
maybe if you have 4 injectors per cyl that would be about 40 per second per injector. not sure of the current rate of injection, but im guessing there is no way to do it with one, or even 2 injectors with current technology.

with a 4 Smoke, you can be revving to 13000, and only need injection at half that rate since it only fires every other time the piston is at TDC. I think the fuel injected 4 Smokes currently use about 2 injectors per cyclinder.

Wasnt that Bimota 500 Vdue supposed to be injected
dont recall that worked out too well
changed to carbs and still didnt sell them..??


Mr Dent would cringe to read that Embarassed
Injection is the current area of development for RG's - works very well and extremely reliable but expensive.
The reason the Bimota BB5 not being a success is that too many of them went back to the factory in a dead way. Dodgy autolube kept letting them down.
