After visiting this site decided to get a sohc 4 to fix and cafe well i ended up getting a 550 one thing that kinda was Little weird was it had coils from a old ford escort?! has anyone else used these type of coils will it kill the bike after i put it back together i kinda like the idea of being different. It "did" run decent with them before I think the cam chain broke but more into that later. Thanks in advance.
