I am not getting any spark from either spark plug. What should I do?

HAVE ANOTHER CDI TO TRY. AND THAN POSSIBLE STATOR. ALSO ALWAYS CHECK ALL WIRES, MICE LOVE OLD SRX,s. 3:16 (YAMMIE TONY)

could be the above or it could also be the kill switch or the key or the tether, all of which can be bypassed by unhooking them from the harness
If you have an ohmeter you might save your self some time by just testing out all of the components and wires. If you don't have a manual, we can help you with specs. But really you are looking for relative numbers not exact numbers.
with any "no spark" condition on any engine, you always start at the source of power and work out, so youll need a multi meter and check the pulsar coil down at the recoil/engine first, make sure it has varying power out put when you pull it over before then moving to the cdi box, then to the coils.

Hey mrviper, what exactly do you mean by "pulsar coil"? I have a 1997 v-max 700sx that has no spark. I have checked kill switch, TORS, & other connections. I think it's what you may be reffering too. Do you have instructions on how to check this ? I'm thinking it's the stator, but don't know how to test.
"pulsar coil" or "source coil" or "pick up coil", all the same thing, its the coil that sends the voltage to your cdi unit. From the cdi the power is stepped up and then sent to the primary ign coil,then to spark plugs. So you want to disconnect the harness down at the engine and insert your multi meter in the wires coming out of the stator, pull the engine over and you should read varying voltage like under 1 volt as the rpm you turn the engine over will be slow.
I will look up the 97 sx engine and tell you which wires to check. The way yamaha tells you to doi it is a simple ohm check which is "ok" but i find alot of differances if its not the correct ambient temp and the reading will be off. By checking for varying voltage, you know if its working or not right away. Then if its working youd move up to the cdi and check the out put wire going to the coils, the voltage should also be varying on the meter when you pull it over, if not, you know its the cdi if the first test showed good.
