    A #60 or #62 main jet. The pilot jet is a non-removable pilot jet tube.

    This is my 3rd Fiddy but after many years I have been out of the game. Just picked up a 05 CRF that has been sitting. It has an 88cc Takagawa with stock carb with Uni Foam Filter. I finally got her running but she bogs at WOT and pops off a couple back fires. Air Filter is clean and recently oiled. Do I need to buy a #60 main jet and adjustable needle? Any additional info would be great appreciated! MERRY CHRISTMAS!!

    You can try the #60 main jet, and it sounds like you might want to drill out the air screw plug if you have one, so you can adjust the air screw. Wouldn't be a bad idea to get the adjustable jet needle as well.

    Any Honda Dealer can order it for you, here is the OEM part number for a 2002 XR50 jet needle kit, the needle has 5 grooves for adjustment - 16012-GEL-701.

    The #60 main jet you may have to get from JetsRus, they are right here
