Hello, My 04 Wr450 keeps blowing the front and rear bulbs. I have checked the magneto and the regulator / rectifier and get the correct readings from the manual. I get 12v at idle at the front and rear lights but it increases to about 25v when i rev the bike!!!!!! Does anyone have any ideas on how to cure this please? My bike needs the annual test so its road legal but no lights = fail so please help if you can otherwise i will be bikeless !!!! Thanks, Lennie.
