Its a very subjective thing.
When I owned air cooled VWs, I knew a super beetle had a flat out level ground no wind top speed of 82mph.
After I did a tune up, there was a country road where I could take the car and hold the pedal down. If I got the timing off or something else was not right, it would not hit 82mph.
I dont know if you could do something similar on your MC - its so freaking fast - maybe a 0 to 60 acceleration time, or track your mpgs to see if its not running right.
The only suggestion I have is run some SeaFoam thru the bike, you might have some varnish in your injectors.
I should change my username to MrSeaFoam
I just did an experiment with my VS650 - I decided to run it on ethanol free regular gas and see if I get better mpgs. The bike seems to be running better, smoother, and cooler (the heat I feel on my pant legs when I stop for a light)...
but I filled it up today. The last tank of 10% ethanol I got 58.5mpg
with this tank of ethanol free gas, I got 58.5mpg - exactly the same, under the same commuting riding conditions.
Even though the bike 'seemed' to be running better to me, I think it was all the placebo effect. If the bike is getting the same fuel-mileage, I dont see how one fuel could have better fuel density per gallon than the other, when it did not show up at the pump.
Maybe the bike is running a little better on the ethanol free gas - maybe Im getting better acceleration, resulting in me riding a little faster all week, which made the fuel economy wash out?
But the bottom line is, the seat of the pants feel is very subjective.
Regular ethanol blend is about $2.80 here. The ethanol free gas is $3.50 If Im going to pay $3 more per tank, and have to drive to one station to get it, Im going to need more than a feeling.
