Cvt tuning is pretty straight foward if you have some basic tools/ skills. Lighter rollers/sliders will get you up to speed quicker, and clutch springs will help get it to the ground If you spent 20-40 bucks you could have a much quicker scoot. Wordslinger likes the 4.5 gram rollers. Shaka has had great luck w/ dr.Pulley sliders. Malossi makes spring kits for your clutch that run around 10 bucks. Believe it or not TIRES make a huge differance in the overall performance of your scoot. I have had the oem Chen-shin, Top of the line Kenda's, and now Avon Viper stryke. The Avons rule. 100 bucks will get those. If you want to get into pipes/carbs/filters, I would suggest doing all of them together to avoid re-tuning for each part.
