Really stripped down my Nolan 102 to clean. Now I'd like to know if anyone has taken apart a J&M Aeromic III. Some of the holes look plugged. I'm afraid sticking in toothpick or something would force what's in there, further in, or damage something inside. It looks like the front and back piece lock together, but before forcing something I thought I'd ask on here. I'm also going to try to figure out how to modify the plastic foam piece that's in the chin bar so there is more room for the mic. I'm also rolling a baseball bat along the part of the foam by the forehead. I got this info from a guy at the Davis Rally in Iowa, that has worked on Nolan helmets.
