Ok I´m somewhat mechanically inclined and have checked for no spark on my cbr. I have checked and found a blown green fuse at the midlle section of the wiring harness of the bike. I still had no spark I hear about the run stop switch But don´t know exact what I´m lookin for . I also have a funny suspicion that the bike has had problem befor and the bike looks to have replaced cdi? Black box on rear tail section. I have test for power at black/ white wire and have no power. Any suggestions?
