1993 Honda Fourtrax 300 4×4 preventative maintenance

Hi, I just recently bought a 1993 Honda Fourtrax 300 4×4. It was just sitting in front of someone’s house with a for sale sign and they wanted it gone. It looked pretty rough with the plastic in rough shape, it had no battery, I kicked it over one time and it started right up. I test drove it and it shifted through all the gears and appeared to be running great.

I just got done repairing the plastic and wrapped it in camo and black and it almost looks new.

Drained the fuel and replaced with new.

Changed the fluids in the engine and all gear boxes

I took it up hunting and rode it pretty hard for about a hour and a half and it runs excellent. These old Honda’s are pretty amazing machines.

My questions is since the machine is over 22 years old and I am assuming very little if any regular maintenance has been performed on it what things should I check, inspect and replace in order of importance to have a well running and reliable machine, thanks.
