I ride a 2002 summit 700. It uses lots of oil. I use a quart for about 6 gallons of gas. That is a 25:1 ratio. I would like to have about a 40:1 ratio. Is there an adjustment other than the cable length adjustment on the pump itself. The dealer replaced the original pump because it was "sticking" and using lots of oil. The new pump uses just as much oil as the old pump did. He said this is normal. I don't believe it. I have ridden sleds and dirt bikes all my life and have never used so much oil. I premix my boat at 50:1. All that extra oil is just a waste and makes a lot of unburned oil smoke clogging up the Rave Valves. Any help?
