I am getting ready to install a dynojet kit in my 04 raptor. I am also installing a pro series air filter kit. That is pretty easy. I am just looking for some do's and do not's when installing the jet kit. I have read some about having to sync the carbs. If all I do is replace the main jets and the needles will I have to worry about syncing the carbs?

 

If you take the carbs out as one you won't have to sync them. just take the bowls off and change the jets.

 

Is this the same for doing the needles too?

 

Hi,I used a Dyno jet kit on my KFX and couldnt get it to run with the kit.I would use the jets that came with your carbs and go up a size or two bigger.I have a 2003 Raptor with a full Yoshi exaust and a Pro design air box and lid it runs the 160 165 jetting.

 

if your changing the needles, u can keep the carbs right in the machine. just take the caps off the top.
