I now that ths is a quad forum but I have both and I just added a yz250 to the collection. What kind of mixing oil should I use? what mixing ratio? how much and what kind of transmission oil? what's a good place for parts? and is it a good dependable bike? So thanks for looking and the replies that I get

 

I run yamalube 2r 32:1
runs fine for me
I only have 2 tanks of fuel run through it htough......I seldom have time to play with my toys.....

 

KLOTZ!
