first things first, check for spark the old fashioned way. take the plug out of your motor and either hold it and ground yourself or ground the spark plug against some metal or your frame. have a friend kick the bike over for you while you watch/ or feel for spark. if you have no spark read on...if you have spark save your eyes the pain.......
check the coil..to test it take the wires going to it and take off the spark plug boots from the plugs and get an ohm meter and make sure to set it to read R X 1 check the resistance between the two main wire terminals(where the black and orange wires were) resistance should be anywhere between 0.28-0.38 ohms if its any higher or lower you may have a bad ignition coil solving your spark problem. another thing to check arethe secondary hookups. set th meter to read R X 1000 and measure the resistance between the plug wire and the terminal that goes with that plug wire. if the meter reads an open circuit take the plug cap off and check it again. if you have continuity then the trouble was in the plug cap. but if it still reads open circuit then you might have a problem with your plug wires.
