Hey guys this seems like a great forum with good information. I have a chance to trade my 89 Honda Shadow 500 for a non running 79 Honda Goldwing. The bike looks good but it would not start. Its been sitting for a while as it has only 20,000 miles on it and the cables are sticky. The choke seems broken at the bracket and it leaks fuel when the pet cock is open. Are parts for these bikes expensive and even if I had to overhaul the fuel and ignition system what would I be looking at spending? Also is there a way to test this for more serious problems like bad headgasket/blown head?
