After a disasterous firstattempt at building a Pro-Stock skate Mac from the case of our trusty late 90's G4 'Sawtooth' Powermac we decided to step-up our efforts and debut the MOTO G4 series! This involved completely gutting the case and building it onto a mini-motorbike frame. We named the project 'Buran' after a space-shuttle the Russians spent billions constructing, but ran out of money before it ever flew. (NB: The bike has ridden once though so maybe 'Spruce Goose' would have been better.)
The pics below catalogue the ongoing conversion process of this astonishing machine from retro-Snapple to superbike.
This was the original concept on which we based the Mac-Moto - bicycle steering and the engine inside the Mac case. Turned out we were using an air-cooled engine so we ended up mounting the engine just in front of the case even though it would have fit inside. I would not advise fitting the engine completely inside the case unless you have a good duct system or a water-cooled motor.
First we removed all the plastic panels and cut apart the Mac case to fit the bike frame. This involved stripping everything inside the case, including the metal drive-tray and the Airport, down to a bare metal box. To make the hinged side-panel lift up instead of down we had to turn the case upside-down to fit onto the bike. This makes the plastic panel-fit not exact, but close enough to screw back on. Rather than have the back of the Mac-case on display at the back of the bike, with all it's sockets and fan holes, we also decided to turn the Mac round so that the smooth case-front would be on show.
