i just saw this thread about your CBR F3. I know this bike well.
That bike had an early generation "ram air" system that if there are any problems could generate a throttle response problem.
If you didn't make any changes and it started running poorly it may be something in the fuel or an idle or pilot jet that needs to be cleaned.

Call our shop. (# is below)

I doubt it's the fuel filter. If the filter was causing the starvation, it would only get worse as the RPM's increase and try to pull more fuel through the filter. Dirty jets or sticky float, something in the carb most likely. I'm in Aurora if you still need a place.

Are you pretty familiar with the F3 design? I haven't been able to get ahold of a Chiltons yet. I'd love to just save everyone's time and frustration and have someone who is familiar tackle it with me.
The fact that other's are reccomending you is pretty heartening.

There's microfiche on ronayers.com or bikebandit.com that shows you where everything is.

Also, check out this thread down a bit and you can download the manual.

You have to pull the tank, and the fuel filter is right under it.

Never worked on an F3 before, that I recall. I don't really think that matters, though. They all have the carbs in the same place. However, a shop that works on tons of bikes might know of a specific problem with that bike and could possibly go straight to the problem.

I would first look for anything obvious, then check all the wiring to make sure it's not a bad connection or plug. Then, it's pull the carbs and clean them. Pretty simple stuff. It can take time, though.

So, am I being "special"? I think that the link has expired and googling free, downloadable manuals isn't working out so well. I will need to call around, or by some miracle see if a library has one. Thanks though.

Check your fuel pump, they do strange things I had like issues. One minute the bike would start and run perfect another day it would act like it was starving for fuel. Pump is easy to get to, pull the fuel line going to the carbs give the starter switch a quick push make sure you cover your fuel line with an old towel so you dont spray or leak fuel all over. You will hear the pump engauge only when the starter is quickly pressed. If the towel is wet you are probably getting ample fuel and it may be ok. The fuel pumps have a little diaphram that sticks or wears out, works or not depending on fuel pressure the pump its self and heat off the engine. Mine acted strange for a couple months, now no problems knock on wood.
good luck

Worked on it this weekend, hopefully fixed it. We will see.
Carbs re-jetted. New fuel filter. Coolant drain and change.
Running like a dream so far. Fingers crossed.

Hey, I used to have an F3 race bike and had the manual on a CD and on my computer. Let me look around the house and see if I still have it. If so, its yours. It was scanned off of a copier, so it isn't perfect but it works.

Hey thanks a ton, but I already got one. I appreciate it though!
