1 set. For more details, check 'technique'. You can find a guide. Or, press here: IGNITION SYSTEM.
VERY IMPORTANT:
If you CANNOT FIND a great mechanical help you, you or the mechanical don't fully understand CJ750, really don't understand the guide, don't know how to check the electric parts, PLEASE DON'T TAKE KIT. That will waste you a lot of time on it.
Make sure you didn't modify your original bike. Otherwise, please back to original at first such like: you already changed coil, rectifier, flywheel, relay, or something like that. Otherwise, please don't waste time, don't buy it. Please contact me at first before buy!!!
