Got 2 new mini bikes from a co-worker. I think one is a Sears roper and other I'm not sure. Both need restored. I figured I'd paint em, slap a predator engine in them and give them to my two nephews (5 and 7) for Christmas and give my cousin and her husband a first aid kit so they're not left out lol. Would like to know what they are. Was thinking of putting 5hp Tecumseh in the Rupp Scrambler I have. Any info greatly appreciated as always
