I'd like to start a thread on All Terrain bikes (4" or better tires). We've just got our Mongoose Beast "Moto-Goosey" running but it's still has a bit more development in the works before we can hit the road. Just put a muffler with SuperTrapp disks on. Seems to work but it's a little loud. Gettin' the Beast to stop was our first priority, so we adapted the front fork and hub to accept a Shimano Hydraulic caliper using a master cylinder from an ATV. Powering was a real challenge since we wanted the engine to mount in urethane bushings for vibration damping. Lots of failed attempts, however it seems to be successful now. The jack-shaft design should lend itself to the 7 speed Dolomite as soon as we get the Beast finished. Here's a couple of shots, hope you like what you see. We're thrilled with it's looks.
