Sell your blast, save some money and buy a fast bike. The blast will never be fast. You're looking at a grand plus to strangle 70 hp out of a bike that wasn't designed to make it. I know you're all about your blast dude, I get it. You have an emotional connection with it. If you want to go fast you're gonna need to upgrade your entire motorcycle choice. I know, I know, 'the guy wants to make his blast bad-ass, let him do it.' Fine, ignore all reason and practicality and spend the money. In the end you're going to want more than it can give you. You can put a tube top and daisy dukes on a fat chick all you want but its not gonna make her hot.
