I've always wanted to remove the air filter box to clean underneath it, but have never been able to because of this bolt. It'* a Torx head and it'* in a real tight spot.
If it were a Allen head, then I would just cut the end of a Allen key to get in there; I've done that before for Allen heads in a tight spot. But this thing is a Torx head; there'* no cutting the end of a Torx key because they're only machined on the end.
If I ever do get it out, I want to replace it with an Allen head bolt. If I ever get it out that is.
