Part number 30500-KSR-711. Dealer take off, removed from 2005-2007 CR125 models that were converted / had complete aftermarket ignitions fitted when they were brand new.  Can also be used on many other CR models that have the wide mount type coils fitted (79mm center-center mount holes) Most of them requiree a longer plug wire so i'll include oen long enough with each sale. Simply screws off and on just like you do with a plug cap. Any shipping can be combined! Please request the combined invoice if you have bought multiple items. (And don't proceed with the payment before you got the combined invoice!)
