Sorted those out, drained and filled with fresh oil and a filter, and hooked up a battery. Found a few fishy spots in the harness where previous attempts at repairs had been shoddily made and hidden with black tape. So, after cleaning it up enough to turn wrenches without looking like a Texas oilman, I took off the plastics and started poking around. And now it just plain wouldn't fire at all. PO mentioned that he 'had it running at the beginning of the season, but it was 'rough' ' and that he had cleaned the carb, but it didn't help much. Managed to find the VIN hiding in there and ran it for giggles. The entire left side of the crankcase was covered in an eighth inch of caked oil mud, as though there had been a catastrophic loss of oil at some point in the past, because it was nowhere near the drain or fill holes. Got it home, and hit it with a healthy dose of bike wash and the pressure washer, more bike wash, a lot of scrubbing, and more pressure washing to get years worth of crud off of it. Average ownership period ranges from 6 months to 2 years. Looked it over and handed him the three bills in exchange for a transferrable registration from 11 years ago, and a STACK of handwritten bills of sale from the last 11 years, since apparently no one has gotten it functional (for long). Showed up about 20 minutes early to find him and his buddy hastily reassembling the pile of plastics into a semi-presentable quad, using some real sweet bulk bin galvanized hex bolts from Tractor Supply Racing Co. Naturally, I'm like 'Hook up the trailer, let's go get this pile of eBay parts!' and hauled ass to this dude's house with 3 crisp Benjamins to wave under his nose. Gotta love Facebook Marketplace, and the crackheads that you can buy things from on there.
