Show us your Funder Wheels kart. Photos help because there’s oftentimes people out there that just don’t know what they have. They may even have a donor kart but don’t know who made it.
I’ve never seen one naked like this. Knew they were cogged-belt-drive though. Look at the “Turbo Torque” bolt-on apparatus on the Briggs. That’s wild but what does it do? Wonder if the belts are available? They might be a COTS item….
