Is it the first piece put on the bike is built around it?
It must be, cause I can’t see someone at the factory spending all day putting those things in.
There have been many discussions on that particular POS. Some have left them out, which I wouldn’t do. Honda put them there for a reason, whether for heat or dirt or whatever, there is a reason.
I’ve considered buying a second one and cutting both so there’s a 1” overlap, drilling some holes and zip tying them together.
Haven’t done it yet cause I always seem to get them in after tons of swearing, cussing

and pushing, pulling.
It might be easier to pull the radiator?
Just keep trying, you'll get it.
Then there's the flap under the radiator, but that's another story.
