I do have a minibike-specific tool box that I bring with my drag bike.
Has everything I need to work on that bike, but nothing great -some Craftsman and other foreign cheap stuff. Mostly Allen wrenches, open end wrenches, couple sockets, screwdrivers, extra fuel line, clutch spring tool, extra jets, plug, fresh oil, etc.
I bought a 1/4" 12-point deep socket for rod bolts, I think from ez bore. I need to by a flywheel puller one of these days.
I think that's it for minibike tools.
