Hey guys I'm new to bike I just picked up a 2k zx6r a month ago. And I have a few questios first of is it hard to change the oil or should I take it to a shop, they quoted me 60 and if the plastiks need to be removed 90. Also my battery is dyeing like if I go riding and it would be fine but some times allof the sudden the battery just gets drained. Don't laugh I'm a noob but do they have an alternator? I've cheked all the fusses and they are fine so is there any thing I should check. If you have a coment you can Im me at plyneon2495 or yahoo Im at ptpowerneon thanks in advance.
