What are you trying to achieve? What's your definition of better educated?
If you're trying to learn about the vehicle overall, check out some reviews by long term owners. I have a 17 minute video that will give you a lot of general information and reflection on this bike:
If you're looking to learn strictly about maintenance, skip reviews and search instead for all of your typical maintenance stuff:
LX 150 oil change, LX 150 belt and pulley replacement, LX 150 spark plug replacement, air filter replacement, brake pad replacement, upgrades, etc.
Those bikes had a LONG run and were very popular, so there is a ton of content out there on them.
