Changed the standard (CHAMPION!) Spark Plug for an NGK Irie-Dium item for a cool $10 ($20 with shipping - Thanks Scooter Parts Co...) My trained Spider Monkey collapsed with PTSD and went away to Rehab, leaving me to try to wheedle and cajole the 5/8" plug socket into position. Mr. Piaggio, could you make it any more difficult to do such a simple, standard maintenance job?! It CAN be done, as I've shown, but add the ER visit for stiches to the wound cut by the frame edges getting your hands in there.
But I digress. The post is about getting horny. Specifically, replacing the anemic, completely unconvincing "Meep" horn with a - BLAAAHHH - air horn.
There's a little dismantling to be sure, but once the floorboard and glove box are off, its pretty easy. I even got the glovebox to reinstall on the first try, and the door actuator works about 60% of the time - actually an improvement.
The final location of the horn assembly is well below the louvers in the horn cover for optimal acoustics, but the thing is so loud it doesn't matter. Texting Prius Pilots will be resoundingly corrected should they drift into my lane!
We start with an Inline Fuse from O'Reilly's. Replaced the 30 Amp unit for a 10. No sense setting the scooter on fire if a wire wears through.
The horn comes with a relay, cheap as it is. The stock horn connectors serve to activate the relay, leaving only the Hot Line from the battery and the line to the horn to attach.
Here the connections are made and the relay affixed to the handy "Ear" of the stock horn bracket
Lurking in the spacious area below the horn cover. You can see the threaded hole where I attached my simple spring steel bracket.
