If they are the same that will be great. I could have been told the wrong info years ago? I have always been interested in the 99 set up. I think the cdi is digital just 00-01. If your 99 flywheel ignition trigger is of by a few degrees you may be able rotate the stator plate & get it back within the timing needed to run the 01 cdi. Definitely update this thread with what you find out. This might be a good alternative for those that want build there own.
