maybe you can help me out man i have just put on a pro flow with a k&N and i have no airbox lid and i got on and rode. it was shooting out flames when i got on it, and i need to know what to do wheres the air/fuel screws on the carb or what can i do to make it run good

 

jet it right!

kc

 

i asked where was the fuel/air screw not if i need to jet it
i do have a jet kit but not sure how to do it

 

Your jeting is going to be to lean all the way through the range...if you have a jet kit install it..if you arn't sure how do a search on re-jetting in the Yamaha forum...ohhh yaahh...the a/f screws are located at the bottom of your carbs recessed into the body of the carb...in is lean out is rich...good luck
