opinions are like ass holes, everyones got one! let the kid spend his money on a cub and detune it. I am sure a builder would just love to take 1500.00 of his money rather than 300.00-500.00! I get so sick of these questions seems alot of people want to build a drag bike but they still want to lug it through the trails. it dont work! I started out like this, then I bought drag pipes, then a lock up then an over ride then alky. now looking back it would have been much cheaper just to build the drag bike and buy a trail bike, rather than buy a bunch of parts, use them for a little while then turn right back around and sell them in order to buy more drag parts.
Its your bike man do what you want with it. but remember to build it for how and where you ride it the most! you will be much happier in the long run. Oh and no matter how had you try, there will always be some one faster! its just a fact of life
