89 KDX200 sharp and precise carb tuning

If you want sharp..I suggest a CGK needle from sudco. start in middle clip then try second from top. Use a 40 pilot with that needle, keep the #6 slide. set airscrew for best off-idle response, non of that highest-idle crap.

BR8es plug, Set the main w/ WOT chops to get 1.5-2 mm of soot on the base of the insulator of a new plug the part you can't see well. cut off the threads to see down in. Don't be ascared if you see a white insulator tip, white means its self-cleaning, like it should. Grey is bad.
