I bought a 2004 SWing on Tuesday with 16K miles. It'll need about $300 worth the parts, so that should keep me busy through Thanksgiving. It has a tall Givi Windshield, Givi topcase, power outlet and JM CB radio. Depending on how complicated it is, I'll likely pull the radio transmitter out.
I've ordered a new plastic exhaust cover from China on eBay, but haven't gotten a tracking number yet. Not feeling great about that.
The rest of the parts are starting to trickle in. It'll need a full stem to stern overhaul, as the previous owner since 2017 didn't have any records-- so.... battery, brake fluid, oil/filter change, air filter, iridium spark plugs, CVT belt, coolant and probably a rear tire for good measure.
The battery was definitely weak; I always plan on a new one unless the seller has a receipt. The seat strut is flaccid, so I'll replace my block of wood with a 4" PVC in the near future. Removed the under seat bulb and installed a battery tender lead to simplify charging.
I'd been lurking around here anonymously a couple of weeks before buying, for due diligence. Thank you for all the good information. The scoot exceeds expectations. Good seating position, good power and predictable ride.
