I'm looking to get a Max II tonight. I called the manufacturer and they said it is a 1991 from the serial number. It has a 2018 predator 670cc motor in it with new tires and wheels. Right now I got it down to $2,000. Does this seem like a fair deal? I don't know a ton about these. Anything in particular I should watch out for? Manufacturer said to check each axel to make sure they are not clunking around as that would mean bad bearings and other possible issues along with rusty chains meaning possible neglect of keeping them greased up properly.
