NEED ALL THE HELP I CAN GET 86 trail boss

Hey*everybody how’s it goin? New here to the forum and new to polaris machines so I’m a little stumped on this 86 trailboss 250 I picked up over the weekend d for $200. Im not new to atvs and am mechanically just dont know what to do with this machine looms like a mini snowmobile motor haha. Let me break down what I’ve found out so far about it……

it’s a real 96 had the vin ran at a dealership.
There is no shift knob for this machine…where is it.suppsed to be located and where does it hook into the transmission?
What size stock carb does it have?
Any known issues with these machines?
Is there any performance upgrades for these that are decent or keep it stock?
How are the tranny on these? Do they require a lot of maintenance or are they strong runners?
I’ll have a whole bunch more questions when I get the chance to keep going into it.
Thanks a lot for the help in advance guys much appreciated.
