I'm new to the forum and Dirt Bikes in general. I just purchased a power-up jet kit and no instructions came with it. If anyone can send me these that would be great...

1. Remove your seat.

2. Unscrew the throttle slide cap. This is where the throttle cable goes in the top of carb.

3. Pull the cap and slide attached to the cable straight out.

4. Change the needle using the one supplied in the kit. Put the clip in the middle position on the needle.

5. Unscrew the band clamp on the air boot at the rear of carb and remove the two 10mm nuts that hold the carb to the intake manifold.

7. Now you can remove the carb from bike (make sure to unhook the vent tube from the clip on the frame)

8. Turn carb upside down over a bucket and gas will drain out.

9. Remove the screws from the bottom of the carb on the float bowl, remove float bowl and you can now see the main jet and pilot jets

10. Replace the main jet and pilot (don't overly tighten or you will break them off in the carb body, not good)

11. Reassemble the reverse of above and you are done except for fine tuning the fuel screw after you get the bike running.
