first race preparations

[BS300ex5]

hey can anyone out there tell me some of the basics for hookin up a quad to drag race in the stock class... so far i have a wb pipe and header, choice of 13 or 14 tooth sprocket (which should i put on), i've put a stright rod in place of the rear shock, filter, holeshots. any other mod ides would be greatly appreciated ... it's just a weekend fair shindig that they are puttin on but it pays out good money so i need some help here thanks for any suggestions

How long are the dragraces? The 13 tooth gives you more take off, while the 14 tooth gives you more top end, I prefer the 14 tooth because it doesnt take that much bottom end out, and since you have those mods already, I dont think you would have to worry about it to much.
