    This is my first build, so far I have built a custom air filter, have posted info elsewhere about it (search nothing fancy air cleaner). Also have modified the exhaust pipe (removing the baffle) hopefully going to fit a mini moto exhaust pipe to it. This was made for my college project. I'm so happy with it! :lol:
    The bikes an aluminium frame with a front disc brake and front suspension. Its very light and wheelies without much effort! But then again I'm only 16 so dont weigh as much.

    Very nice. And a great photo. A HappyTime glamour shot! The upward tilt makes it look like its straining to go.

    Edit: Man, I just saw your exhaust blowout post. Whoa. Carp welds for sure.

    Good looking bike. I'm gonna have to do something like that with my Trek. Good work.

    Is it just me, or does it look like the fuel filter is mounted backwards?

    thanks guys!
  7. It is, but so's mine. It's ok as long as you don't turn it around after using it. It still works, you just can't see the particulate build up in the filter paper.
