Just remember when you get stuck or are having trouble this is the same way most of us started learning.
And the bike you have is just about perfect for you to learn with.
Stick with it, the things you learn apply to more things than just the bike.
If your getting frustrated or angry ,walk away,take a break ,have a smoke or a drink or a cuppa whatever you like.This will save you money and time in the long run.
Have a look for some basic motorcycle mechanical books
Haven't read those myself just an example but I've got a bookshelf full of similar titles,one in particular still gets pulled down to check on every now and then had it for 31 years [shit what happened?]but it's simple and doesn't assume you know anything and they are the most useful ,to me anyway.

basic as hell but thats how you should begin.A little dated now, but hey I like old bikes.
