How much hp?
 

I was curious of the horsepower in a '99 F4?

I think I remember reading 102 stock at the crank.

acceleration;CBR600F-X and F-Y models
time taken to cover a 1/4 mile from a standing start 11.2seconds

F-X being the 1999 model and F-Y being the 2000 model

Whats this I hear about the F4 have 105 HP?

You're on about models after the fx and fy, the fuel injected and sport versions; F-1 and FS-1 onward and its actually 108bhp(80.5kw)@12,500rpm according to my haynes manual.

So our bikes aren't fuel injected? What are they?

RE: How much hp?
 

They are still carbuerated. The F4I model in 2001 started the fuel-injected cbr's.

As far as HP goes, they run around 93 stock, but with a can and jet kit, you may be able to get 100 hp.

Yep as adam said, the F-X and F-Y models are carbuerated. Then the F-1 (F4I) and onwards are fuel injected systems.
So any thing including and before the F-Y on the CBR F models is carbed.

What are the advantages/disadvantages of having a carb engine?
