While it's not really a minibike I did get it in Windber and it's pretty small.
AMF Roadmaster xl moped. Was seized but since I got it home I've got it unstuck and it does have fire. Unfortunately it did have water inside at some point so both connecting rod bearings were very rusty. New ones...
Welcome to the fun, DMPs are pretty rare being a Canadian bike. My brother (bigrob) on this forum has rebuilt three a, scamper and a couple of the trail champs like yours. Hopefully he will chime in with some advice. Pretty sure there are build threads on them. All the best Jay.
We used to have a Tomos no-ped for my wife. Was a great little bike. Parts are available for the engine. Had a pipe and larger jet in the carb and I drove it more than she did. I always thought one of those little dirt bikes would be fun. At that price what have you got to lose.
