Hey guys just recently bought a 2019 mt09 from the dealer everything was working good on it and then I noticed one day while I was riding that my horn didn't work didn't think anything of it.... Later that day I got in the mail my M4 exhaust which I put on and took it for a test ride to see how it sounded. While I was stopped at a light someone told me I had no taillight and then I realized I also didn't had any running lights. I went home and did some research and went and got a box of 7.5a fuses and replaced it. But when I cycle the bike with the key it keeps blowing. I unplugged the rear taillight, rear turn signals and the horn and it still keeps blowing and I have no idea why it keeps blowing. Any suggestions??? Also another thought I had was that maybe the o2 sensor acted as some sort of ground and the paint from the exhaust could prevent a good ground causing it to blow? Any suggestions would be greatly appreciated!!
