Throttle cable adj. for more power on 400ex?
#3
here we go again....Start by removing the black air intake boot on the back side of the carb. Look into the large hole and the choke will be visible. Beyond the choke, work the thumb throttle and you will see the "slide" moving up and down.
At full throttle, the slide should be seated all the way to the top (dissapearing from sight). Take your finger and check for further movement if there is room and adjust the cable at the thumb throttle till the slide remains at the top position at full throttle.
You can bet the ranch that there will be room to raise it on a 2000 model!...probably at least 3\8ths of an inch. Re-install the boot and let her rip.
