I would check the welds over as for wiring the insulation on the wires is going to fade if it is in the sun and if you are going to store it remove to + terminal on the battery this should help fight corrosion of connectors should the ignition be left on or anything is wired up bypassing the ignition. You should be able to get cream tank treatment off of
Ebay on your local motorcycle shop. Also with the electrical connectors I would get some dielectrical grease and coat the inside of the conectors to fight corrosion. Later if you want you can upgrade wiring to larger guage better quality wiring and connectors like bullets or Deans R/C plug connectors. Can you post a pic of the bike? If not PM me and you can Email it to me. Thanks Wes
