How can I raise MPG?

[laxs1308]

Any advantage to run 91 octane or 93 as apposed to 87? not necessarily with mpg's but for the health of the sled?

More octane on a motor that only requires 87 octane does not have any know benifits in power or milage.

There is no difference in the gas, it is just the resistance to which it will ignite. Ever heard of someone saying there engine was knocking and they used mid grade or super and it ran fine? That means that 87 was igniting before piston got to top dead center piston was trying to compress the explosion, mid or super takes longer to ignite allows piston to get to top dead center before ignition. So no it will do absolutley nothing don't let anyone tell you different!

Outside whats already mentioned, I know heavy ski pressure and or dualies on the skis play a big roll in milage from extra drag.
I also noticed many clutch kits raise RPM at normal trail operating speeds which also adds thirst.

Like Dano said carbide drag and/or nose weight,clutches.i also heard the >Flux Capacitor< helps some?

I'm going to got through the sled this weekend. I lengthened the front strap and tightened the transfer rod on the trail to remove the ski pressure. I will check that everything with the clutches and belts are good, back off the chain tension. check the skid for wear. Next trip is our family New Years run. should be a lot easier to take it easy and check the results.

If you use ski savers take them off for a try. Helped my mileage.

drive down hill, draft the guy in front of you, tuck behind the windshield, go with the wind, drive on ice all you can...

or just drive it and dont worry about it.

Actually screw the 14mpg. All I need is two more gallons of gas. How can I get that?

 

[Mikecam]

Small rack to hold it. Pictures anyone?

 

[lawmanbsi]

found this one gallon 9.5" x 13.25" x 3"

Don't loosen the chain you will be haulin on UP trails & don't want that chain slapping around..........bad things can happen if you do that not worth slight increae in mpg.

x2, if chain were too tight, you would get 0 mpg as the case would be seized or blown
