    I'm not sure if someone already thought of this one, but I thought I might as well get a laugh out of it. I dreamt this up a few years ago. Hope this diagram makes sense: J P A T C O K ---~~~~~~~== Fourth...

    Very old scooter design

    A friend sent me this photo. It doesn't appear home built, or if it was, it was a pretty good design job.

    What are these aluminium wheels from?

    Found these on ebay for $200 haha. I really wanna know what minibikes came with them. They are small and I actually like the simple design of them.

    Brister's Design & Manufacturing minibike

    Picked this bike up this morning before work at a garage sale. It's labeled as a Brister's Design and Manufacturing minibike, but it's basically a Murray Track2 only a little bigger. Runs, all be it rough. Needs a good carb cleaning. Came with the owners manual.

    HS40 shroud

    I need a shroud for my rupp build. The one I have is cracked along the front edge where it overlaps the head. I have an ID plate that I'm going to transfer over, so it doesn't need to have it. It does need to be a round-shroud design (1970). I think the H35 shrouds would work as well. I'd prefer...

    Not Your Typical Sebac Shock - Disassembly and Identification of Specific Application

    I picked up a set of Sebacs recently that were not of the usually minibike variety. I'm assuming they might be from a moped. Can anyone confirm? They are the same length as the common minibike variety, about 13" but have a different eye casting design on each end. They are genuine Sebac brand...

    Springer Front End Fab for My 212 Monster

    I have been modifying a MonsterMoto MMB80. I installed the "big block" and added a torque converter which required some modification to the frame. I love the little bike so much I decided to make some suspension. It's just a simple springer design. I made all the pieces and next...

    Doodlebug problems ?

    Every now and then I read on threads about Doodlebugs having problems and they should be removed from the market. I am talking about the older ones of course. I believe there is not enough data on the new ones.I really can't find definite reasons why. Does anyone know these reasons, or is it...
