Stick with what you got.......
..........for right now at least.
A week is not a lot of time to make cables and get carbs dialed in.
Also, depending on what throttle you are planning on using, you may have to modify the gear mechanism to get it to open the slide carbs all the way. The stock setup on mine only gave me about 3/4 throttle. If need be I'll take a pic or two on how I modified mine to give you some idea.
Also, the exposed wire length will be too short to fit the slide so grinding the barrel won't be enough, you'll have to shorten the outer cable to effectively lengthen the inner cable.
Sorry, got to leave for work but pm me if you got questions about cables and such.
