Just beginning to work on my own bikes and picked up a good project cr125 the other day. It is a 2003. The bike isn’t getting spark and my much more mechanically inclined friend has told me that he thinks its the ignition coil. However, after turning the internet upside down I have not been able to find another oem style one. The part number is 30500-KZ4-L31. My question is, can I use a ignition coil from an earlier/later cr125r, or a 2003 cr250r? Thank you in advance for any help you can give me.
