Torqued-Up - I have been trying to decide for a while now which 50cc motor to get. Have thought about the DA as one of the possibilities but I'm concerned given the problems some people are having. If you haven't read through the thread below, you might want to before making a decision one way or the other. (As an alternative, a couple people at the field have Brison 3.2s and really like them).
