I just picked up a 1991 cr125r and i'm having problems with the ignition system.The previous owner has had many problems with spark on this bike. The coil has been replaced and the stator. I need to check the timing because the previous owner tried to change/set the timing because of changing the components and tear down. I have read if the timing is off it could cause overheating, hard starting, etc. Can anyone advise me on the correct procedure for checking and setting the timing? And also checking ohms readings on ig system components? I'm trying to trace down this problem. I suspect the cdi unit is bad but i want to make sure, i dont know if you can test the unit or not. Any help would be apreciated, thank you....
