should be other way around, ethanol mode selects 3% more fuel
If you're adding more fuel, the oil mixture will be leaner and will burn cleaner. Therefore less smoke in ethanol mode.

Hmmmm... let's take a look at that.

Say you are running 50:1 with the switch in the 'regular' mode. Going to the 'ethanol' mode adds 3% more gas. 3% of 50 (the gasoline portion of the ratio) equals 1.5, so the result from changing from regular to ethanol changes your ratio from 50:1 to 51.5:1

Meanwhile your fuel to air mixture is 3% higher.

Think that will make it smoke less

My oil pump rod took 6 turns and went from a ratio of 72 to1 to 54.8 to1. I will probably change the rod setting until I get it to 60 to1. BTW at 72 to 1 my pistons were scuffed and the rings were shot at 1600+ miles. Got it back last week with new pistons and rings and it brought the motor back to life.

1500 miles on mine and a consistent 64:1 ratio. i am still taking it to the dealership for updates friday, but i hope it doesnt make it too rich. i am goin to have them look at my pistons and stuff but my compression seems to be good and still has great power.

Did the rod update myself. Could have gone 3 turns but only went two. I swear to GOD there was no change in oil usage - if anything it could have gone up 1 or 2 points. We'll see more this weekend - my first two rides were only 60 and 84 miles. Sled does seem to be down a bit on power (only would do 91 MPH on good hard pack _ but that was the first top end run I did with studs. 153 studs slow you down that much??? :huh: ). Pistons show no scuff marks at all but do show some blow by. Can you buy just rings?
