With my 1990 Indy Trail (488cc, fan) I only get 80 miles per tank. My cousin has a 1997 Indy Trail and easily gets 120 miles per tank. We always ride together at the same pace why is his milage so much better???
i have the same problem my n my friend both got 600 tripples. his is a zrt 600 mines an xcr 600. mine got 38mm carbs n his got 36mm carbs but in the same distance mine burns $7 more. i wouldnt think the carbs would make that much diff.
Not sure on gearing, clutching is the same except the 1997 has a blue primary sprin. Both have metal skis with plastic skins. My track tension is adjusted right to spec. The jets are the ones that came from factory (plugs burn perfect).
The only real difference is that I weigh 60 pounds more than my cousin.
But I would believe your sheet that came with sled. Weight could a something to do with it, but I can't imagine that much???
Could be a combination of weight, jetting and a 7 year newer sled with a tuned pipe that "breathes" easier and has been worked on over the years to achieve maximum efficiency
OK...just a bit here, If you guys ride together, it doesn't matter how big your tank is. If you ride the same distance as your cousin, you are using sim gas w/thesame amount of riding, you are getting less mileage, or kilometerage (LOL) as it were.
Mileage divided by fuel amount will yield fuel effiency.
its the same size tank doesn't atke a rocket scientist to see his mileage is that much worse. 60 pounds diff helps a little. Gearing could be an important part, maybe that his sled being newer is a little more efficient? better compression, cleaner and newer carb designs, as well as teh exhaust mentioned. Are you sure the selds produce the same power? ports on the cylinders are probably different along with ehads and any number of other htings. Sleds most likely weigh different amoutns as well.
