Here Is a picture of my friends Flattrack Z.Its rolling on 12's We tried a stock 140YX to see how it ran. Its not as fast as the old school honda motor but its real close. Were building a few hopped up motors and trying some different pipes. Im building a new bike like it with a few changes.We plan on doing some racing when the weather cools off. This bike is a blast and handles awesome! were going to repaint this one and do a few updates.
