Taking all of the slack out of the throttle cable can be very bad. Rev the motor and look at the inner most sleeve through the slit. (you may have to turn the whole assemble to get a visual.) Now pull the clutch to override the Rekluse. The inner sleeve should have a 1/16 th of an inch before it bottoms out. If it bottoms out, then the Rekluse is NOT fully engaging. This is BAD! If there is to much slack or the inner most sleeve is not close enough to bottoming out, it will allow the balls ramp up before the spring has a chance to stop it. This will cause drag and partial disengagement. Remember this adjustment is done with the cable and NOT the override spring adjustment. Remember all of these specs are when the motor is revved and the clutch is engaged!
