RBYM Posted April 3, 2010 My friend picked up a good running 87 yz125 for $175. He plans on putting a new top end on it fairly soon to be on the safe side. It runs great and isn't in bad shape. He changed the oil and it was black and was as thin as water. But he is running 60:1 and insist that it runs great and is the perfect mix because there is no spooge. I tell him to run 32:1 but he won't listen. Share this post Link to post Share on other sites
