2002 GL 1800 Goldwing 102500 miles

I bought this bike from a guy who was not good at repairing things just good at butchering things! it had the bowl of wiring under the seat 2 sets of leds front and rear cameras that were falling hitting the finders no rear brakes when i went out of his driveway after not being able tests drive it only his wife and son were there when i got to his house. Be carefull when buying a used bike i should of known there was something fishy when he said it wasn't about the bike it was about the Goldwing club he was in! I am a retired senior master technician with Subaru i new nothing about Goldwing's but i sure do now i have done alot servicing and repairs on it and new tires if i didnt repair it myself i would of been in way over my head in it buy something with lower miles and good service records.
