LI riders

If so, I have covid lol, in the past 3 months I have bought 6.
04 Suzuki Quad runner 400
86 Kawasaki bayou 185
96 Polaris magnum 425
95 Polaris trail blazer 250
03 bombardier 175 rally
92 Yamaha moto 4 350 

This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
 
My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

Does anyone use GPS, whether on a device or app to record their ATV trail rides? I have been thinking about a section where our members can upload let's say a .gpx file and share their rides on a google map for others to see where there are riding areas. Not sure if this is something of interest or how much it would be used, so just trying to get an idea.
Importing routes from files like xml, lmx, tour, freshroute, gpx, kmz, kml

I am in the process of puting it back together after replacing the DPS gearbox.
The manual I have states that it will need to be flashed by a dealer. Is this still true?
Also , I have a mystery bolt That I cannot remember where it goes. M6x 70 or so.  Hex head with a flat washer.I will try to attach a pic.
Pic is no go for now....Cox issue I will try again later
TIA

Hello from southeast Georgia. Was gifted a 2000 Yamaha bear tracker with out a carb or battery and looking like it had seen better days. Was told it had sat for about three years. Explained a lot. Put a carb on and a battery in and it started right up. Surprised the heck out of me  Anyhow as stated in my opening I am  78 years old with a very long motorcycle backgground but brand new to atv's. Anyone else out here from Georgia? Would like to meet up with some folks for a ride or two. Looks like a great site. Thanks for having me.
