BINGO that is your magic number,, however remember you can allways make it shorter, but ??? well you know. i would subtract 1/8" from the magic number, if you have an adjuster nut on the topset, and none if you don't. 9. measure the cable from the bottom of the "end" and cut with a good set of cutters so it don't frey the cable too bad. 10. solder the new end on and reinstall the cable. 11. reinstall the idle screw , screw it in untill you can tell it is just beggining to lift the slide, then go in one more full turn. 12. make needed cable adjustmensts, so you have just a bit of freeplay in the cable when all is reconnected. 13. start the unit and set your idle screw where you like it. 14. while idling twist the handlebars completely from right to left to see if the idle changes. if it rev's up a little you need to add more freeplay in the cable. now try again untill it don't change the idle RPM's 15 now go for a ride to cool off you earned it !!!!
