I dont know whether this problem is in the carbs or what, but it is kinda annoying.

Whenever im at a low rpm getting ready to accelerate, the engine hesitates before it goes. from about 2000 rpm all the way to redline, there is no hesitation. putting the choke on about half way seems to help greatly. any help is appreciated! thanks in advance

EDIT: If anyone knows where to find the mixture screws on the carbs let me know cause this could fix my problem!

 

well i have a 01 zx7r so i'll tell you what i know from my experiences. First, do a good cleaning on the carbs. I'd say atleast 4-5 cans minimum. This means take the carbs apart when you clean them. The idle mixture screw is at the bottom of each of the carbs. I'm not sure as to what the factory settings are, but I have a dynojet kit on my bike are they are 2.5 turns out from closed. Its must easier to get to these screws if you take the carbs off the bike. i would do the cleaning first and see if that helps. my guess the only time u see this problem is when taking off. i idle my bike at 1500 rpms and pretty much keep the revvs aboove b/c of the jet kit. I even think my factory jetting is designed for about 2k.
