The Honda dealer who did my fuel pump recall had trouble with the rear panel.
Today the dealer sent a tech 30 miles to replace the panel with a new one, in my garage! At first he was going to collect it and return it to me - then he had a better idea. Send the tech with the new parts.
The problem....

4 yellow pins, several edge attachment points and one screw hold the red cover on.

Edge tabs were broken....

These clip into the black metal edge of the hold rail...

Here....

All fixed!

My comments: Release the side panel enough to free the tip of the panel, then lift straight up to release the yellow pins at the top of the "U", then push down then pry out with finger tips to release edge tabs around, then work to release the two center yellow pins.
THe technician's comments: rubber gromets in those pin holes would be much better. The edge tabs were over-kill. (I had a tube of silicone grease ready to butter the new piece - but the tech brought his own)
We chatted while he worked - We talked PCX owners - and their reluctance to get their valves checked. I mentioned that forum & youtube PCX owners seem to work at convincing each other that a valve check is not necessary. He said he would quickly get kicked off of a forum if he expressed himself on that subject. I said I heard from the salesman that some PCX's come in sounding like popcorn machines - the tech said he has "seen them a lot worse than that....and it can be an expensive repair."
This young fellow was polite and efficient - he had new parts and tools and the manual.
I thanked him for making a house call! He said it was only fair since they damaged a part while doing a warranty repair. 60 miles round trip!
Also, he said I could get a new opener dampner under warranty - but it would only be the same part that is failing on my scooter and the new one in their dealership.
