Um... just for your future reference, if you come here asking for opinions, you will get a different one from every person who posts. We might all have the same personal opinion of you, but people will all tell you different things about performance parts. It happens very clearly on the Puch performance pipe threads, if you care to go look and see more examples. You asked for advice, and now you have 20 different versions of what to do. Follow whichever advice you like best. If it doesn't turn out well, pick different advice using what you learned. Wash, rinse, repeat. There are some things that are best learned from experience, rather than from what some people write on forums.
But really, exactly what Ryan said. Go do something productive. Shit talking people on a moped forum is not productive. When you can blast our asses in a drag race, please come back, and have pics, or else we'll tell you it didn't happen.
