wuz up guys and gals. well i pick up a 00 cbr f4 yesterdat for the lowlow. here the problem...

it will start and idle normal when the "choke* is pulled all the way back.but when i try to give it some throttle it cut off and dies.?

I change out the gas,sprayed card cleaner in the carbs but it stil dies when giving it throttle.

any info or suggestions will be a great help.

 

Sounds like you have an air/fuel problem. If you idle with the choke pulled, there's an issue for sure. I'd say rebuild/have the carb rebuilt. This is however dependant on whether or not your air cleaner is in good shape, check it.

 

the air cleaner is in good shape.it a k/n filter.i'm going to replace the fuel filter and have the carbs cleaned. we'll see

thank you ..

 

BUMP ______ I have a 2000 cbr600f4 and was wondering if this has been cured! I just ran through the carbs...Seems like its getting too much air...I DO have the ram air tubes off of the bike, am running a K&N filter AND it has a Muzzy exhaust...I just got it like this a week ago and have it fitted with a cbr1000rr kit..Definately looks nasty but runs like crap! i have to eeease on the throttle or else it will die!..I figure either the bike needs to be jetted or omitting the ram air tubes and covers allows for too much air at lower rpms? i'll try taping off the the airbox holes and report back..

 

clean929 hasn't been on the forum since 2008. I doubt you're going to find out. Start a new thread. I'm locking this one.
