i have a 98 cbr 600 f3 and i took it to the shop and had the carbs synced and cleaned and what not, new plugs and it is still cutting out in lower third sometimes top of second...fourth gear on up?? forget it.
it acts as if it isnt getting enough fuel, well found out today that its missing the lower airbox that uses a vacuum to control air flow to the slides or something like that....not real sure of the parts actual name.
if anyone could help me in this area it would be greatly appreciated.
but as it stands 55mph is the best i can do....thanks in advance.

 

Just curious how much did it cost you to have your carbs synced and clean and what not from the shop?

As for the airbox problem, thats crazy. Was there an airbox on it when you took it in to the shop? Did they forget to put it back on or what?

I think this is what your looking for though.

Go to this website and just look up the part you are looking for. It should be the first part that pops up. But yeah just give that a go and you should be able to find it pretty easy.

Let me know what you think. Thanks man.

 

well i bought the bike used....wasnt aware that the box was missing...the one on top of the carbs is there with the air filter in it..cost me um 65 bucks a carb. plus 65 for one hour labor and 12 for shops costs
