i couldnt comment as to if its worth doing a course or not...but i knew nothing, like really nothing when i bought mine a few months ago and im an office lad so no technical background....best thing I did was get a haynes manual as its simple step by step guides are really good,
also as you do things..ask on here for advice there is always someone whos done it and can offer advice and put your mind at rest.
from knowing nothing..in the last few months I have changed air filter, changed oil and oil filter, learnt to reajust levers (sounds simple but i didnt know!) clean and lubricate chain..properly,....I changed the main jets and had the carbs out the bike (lots and lots of advice from the org on that one couldnt of done it without them)

so if you dont have one, IMO id get a haynes manual first and have a read
