Best top and bottom end on the market!!

I've been ridding mx for years and have tried a few top and bottom end kit but the price and the quality of this kit is amazing. Plus the power of the bike from the stock it astounding, the bottom end power is through the roof. To anyone who is not sure weather or not to buy this, it's a must.
