First thing to do is change out the primary spring. The EPI Pink or Dalton Blue are excellent on stock Vs. Next take the stock snorkel off, it faces backwards and is too restrictive. Jet up one size or two to take advantage of the better air flow. If you've got plenty oif cash add a pipe at the same time. Most of the duals flow very well, DMC's, HMF's, and LTE's are popular, but are fairly loud. if sound is an issue, the Muzzy two into one pipe sounds amazing, is quiet, and makes tons of low and mid range power. Get your jetting spot-on! This thing is very finicky to jetting and takes some tuning to get it right. One jet size off can mean the difference between getting passed and winning drag races. Once it is dialed in, you can take more advantage of that power and add a more aggressive spring like the Dalton Orange/Blue and get 4 mph on the top end by adding the Dalton Overdrive cover plate. If you do all of the above, you have a very fun machine for just about anytype of riding. At this point you will ahve plenty of speed to outrun the suspensions capabilities! That is when it gets really expensive! By far the best mod for the V=force is a set of aftermarket shocks, second best mod is a steering stablizer.

By the way a CDI does very little on a stock V, it already has a much better CDi than the Prairie, so you won't see the same gains. And nobody has a Turbo working yet, and they are about $5000 on up. You will not need a turbo if you can't hang on to the bucking beast in the whoops!!!!!
