Just found OldMiniBikes. Looks like a great site! I hope someone can help me out.I`m trying to restore a Bonanza Mini Chopper for my son.I`ve had it for a while,and he just spotted in in the garage.It`s missing the motor,chain guard, and gas tank,but everything else seems to be there.This one has the jack shaft still intact.I`m wondering if it should have the 4hp Tecumseh or ?? I have an old Harley alum. oil tank that looks about the same size as the gas tank i`ve seen in other pictures of the bike...It should work...I hope! Can anyone help me out with a complete motor and/or chain guard for the bike?,or point me in the right direction? His B`Days in late May.I`m hoping to have it done then. Thanks in advance for any help! Mark on the Jersey Shore.
