    Going with a Specialized Crossroads

    Just picked this up for a song on CL. ($100) I've had a new Grubee Skyhawk 66cc kit sitting for over a month waiting to find the right bike. Wanted to go with something with a front suspension to sooth out that ride a bit. (2 past back surgeries). Also needed something big, as I'm 6'3" and...

    Something actually worth checking out

    I ran across this video which demonstrates the difference in sound level between a regular expansion chamber and a belly bleed approach. https://www.youtube.com/watch?v=qsQ_mRrqrTs

    New Pipe Build

    Ok, I knew it was going to happen eventually, just didn't expect it to happen earlier today but my modified pocketbike pipe broke off at the lower mounting tab. I was going to just weld the tab back on and carry on with breaking in my newly built engine but once I saw just how thin the metal was...

    Handle Bar Exhaust?? YEP!!

    So i just wanted to share a trick I found . I ordered one of those little Banana expansion chambers for my Schwinn Clairmont and the thing was not going to fit. The angel was all wrong. So I cut each end off of the Banana. It is symmetrical so it does not matter what end is what. I cut my stock...

    Anyone out there with a "BoosBottle Industries" Expansion Chamber??

    This is my first post. Anyways, I just got my 66cc bike kit mostly put together and I ordered a few upgrades with it at the same time. For starters, I put the boost bottle on.
