I was having problems with my oil change today and I called Zortness to tell him. He said to check the Australian Yamaha site for the manual. Yup, it was there for FREE!! Not sure how many Yamaha models it covers, but it's worth a look if you got a Yamaha. They're in pdf format and I now have a copy saved to my desktop. Good shit.
