I think I've blown the ignition circuit of the CDI on my MC21... Powervalves cycle but nothing else. Think it might be self inflicted as I just plugged in a DMR derestriction harness and might have confused the CDI as I still have a M-Max box still plugged in. My question is - repair 30 year old CDI or replace with Zeeltronic or Ignitech? The cost of any of these solutions is pretty similar, any thoughts or suggestions are most welcome..... Oh yeah - I live in Australia! Cheers! Ben.....
