Hey guys, you have'nt heard from me before. Well, I'm new to this board and recently found it becasue I just bought an 85 250R. Its in really good shape, a very nice bike. I just have one question. Today I started it up and was playing with the idle screw above the choke. My bike died, then would'nt start. I took out the plug and it seems to have no spark. I just wanted to know if playing with the idle while running could possibly screw up the spark plug. I'm not too "trike technical" so be nice. Any help.advice.reassurance would be appreciated.
