Ok i need some ideas i a have a 2007 Polaris 600 HO (CARB) sled and my fuel econmy is terrible has anyone experienced this. I mean i am going 40 miles per tank and i am out. Is anyone out there doing any better or had this problem and fixed. I am jetted for 6000-8000 ft and all looks good far as burn rate on plug and piston wash. I pulled the line out of the tank and it goes all the way too the back of the seat very long. So when i run out of fuel i look in tank and there is still 2-2 1/2 gallons in it however all up towards the front of tank. I am thinking cutting fuel line and keeping it towards the front more. Any ideas will be great Thanks...
