Fuel mileage got better after air/slip-on/fuel-pak ???
Is this unusual? My fuel mileage has actually improved after putting on SE air cleaner, V&H ovals and V&H fuel pak on my 08. Bike run's great, but I expected it to add more fuel, so how can I be getter better mileage?? Went from 45mpg to 50mpg in similar mostly back-highway riding.

I dont think my bike got 50 ever. Rough estimates are over slightly over 40. I have only tested the milage when it was stock and havnt did one since but ut seems about the same? I am curious to see if others got better? Good thread King.

This MPG thing pops up now and again...I hear that if you live in the mountains you get better mileage. I won't believe anyone gets 50mpg on a bagger unless I see it, sorry. 40-43 mpg is doing good on a STOCK bike.

A little more information on this for those of you surprised with the absolute mpg I list. Riding at high elevation WILL increase your gas mileage because there is less air available to mix with the gas on a FI vehicle. I also have a 1000cc FI crotch-rocket and it gets much higher mpg in the mountains than when I take it to sea level. That's the good part. The bad part is you also lose horsepower at elevation. I have read 3% for every 1000 feet gain in elevation. That means that at 5000 feet, I make 15% less horsepower than at sea level. I presume that means 15% better mpg than at sea level. 50 mpg at 5000 elevation equals about 43 mpg at sea level. Also, my calcs are using the mileage as given by the H-D odometer, which I have read can be optimistic by a few %, so that can also inflate the mpg, but only by a little.
Anyway, my real question was around my surprise that after adding the SE air cleaner, V&H slip-ons and V&H fuel-pak that the mileage would improve, becausethose changes allow more airinto the motor and the fuel-paktricks the ECM into adding more fuel. Didn't make sense to me? Looks like most so far are seeing LOWER mpg with those changes?
