3 quarts of oil 15$, a filter 15$, my first oils change 30$, sounds like you got ripped off...haha The oil is so easy to change, you dont even have to take the fairing off, just the bottom screw, you'll need a filter wrench from auto zone, an oil pan, and a general socket set... I'm no gear head by any means...
all you gotta do:
1) warm up the bike to about 150º
2) drain all the oil
3) take out the old filter and put in the new, when putting the new one on just make sure you fill it up about 1/4 of the way and get the seal wet..hand tight(you'll thank for that next time...lol)
4) put the oil plug back in, nice and cleaned off from where you dropped it in the oil pan.
5) fill up the oil
6) let the bike run for about 2-3 minutes, and use a flashlight and check for any leaks...
enjoy...
FYI: every service is different, all you gotta do is look in the manual... the first its a once over, oil change, and chain check... if you rode it right for the first 600 miles it shouldnt be bad...
