Hey guys im new to the motorcycle scene i just bought a 1983 shadow 500. The only problem is it dosnt start all the time and when it does it runs for awhile then dies and wont start again for about an hour. The PO has the starter rigged to a button on the side of the bike, i dont know if this has anything to do with it? He also said that he thought the bike needed new coils...i have no clue if this is true or not. thankyou guys!
