Fill gas tank to the top, burp it and top it off. Mark your oil level before you ride. After ride measure how much oil you use to fill it back up to that mark. Fill your sled up with gas back to full, burp it and fill it some more to top it off at the gas staion. You will now have your fuel to oil ratio. It should be somewhere around 35 to 1 to be safe. Some guys lean it out to 40 to 1.
