I ride with a 340 Polaris. If he burns 3 gallons of fuel I usually burn 7 to 8 gallons. I wouldn't think that the size difference in the machines would account for that much. I replaced the plugs and checked the fuel lines.

I have a 1991 Arctic cat jag 440 which is burning 3 times the amount of fuel as the other sleds I ride with. I tryed cleaning and adjusting the carborator with no effect. Any suggestions as to why this may be happening?
