The center rear screw on my air filter was stripped. The inside of air box stayed clean so lid was still sealing. Bought a replacement air box just incase. Was changeing rear shock so since the gas tank was out I tried to replace air box. The 4 screws holding the box to the injectors were very tight. I got them out and tried to install new box and couldn't get holes in box to line up with holes in injectores. The uppper front left of air box is contacting 1 inch horizontal frame tube. The old box didn't line up well either I expect they tweaked the box a little and tightened the screws tight to make sure 0 ring seated. I want to cut a hole in the box to make it clear the frame. What should I patch the hole with that will hold and not effect oxygen sensor?
