85 Big Red 250es Question

[Big Red 250es]

I just recently purchased an 85 Big red 250es with only 1 problem it has no spark at the plug. Im just wondering what I should look for to fix this problem. Any suggestion would be helpful, Thanks.

Start with a new plug, then go up the electrical line with a tester and check the sparkplug wire, then coil, until you reach the CDI.

I Also Just Bought The Same. I Heated The Coil Up Then Tryed It And That Gave Me Spark But Am Still Trying To Keep It Running
