- March 10, 2012, 14:19:45 PMOk, then...Just got back from a 100 mile road trip. I filled the tank before I left. I scribed a mark inside the fuel filler neck so I can always refill to the same level. My new air filter set up is the only change since last year. Wind from the south at about 30 mph, temp 60 deg. Speed was 70...I set the throttle lock at 70 and left it there... it's more bout steady throttle than steady speed at this point. Up and down hill, let the wind and terrain do what ever. One hill I have always lost 10 mph on only cost me 5 this time..Got to my first destination and refilled the tank.......39.9 miles... .768 gallons...51.953 mpg!!!!!!!!!!!!!I believe I have a winner here. The absolute best I ever got before was 48 keeping the speed down to 60...

- March 10, 2012, 11:16:03 AMBased upon rumor... and how the 800 is being used... the 800 usually averages in the high 40's and the 1500 in the low 40's. Individuals will get better and worse based upon the bike, the rider, the weather, the terrain, the riding style, mods, etc. I've seen claims of 25mpg up to 60mpg... still think the 40's is more typical.

- March 10, 2012, 10:26:06 AMMy 1500 is stock(performance wise)except for Vance & Hines pipes. Fully loaded, 2-up, we averaged right around 40mpg on our road trip last year. Some of the backroad, lazy stretches we hit as high as 47mpg(the exception, not rule, lol!) I've found that my mpg is directly affected by the twist in my wrist. I'm ok with that 
My Vn900 gets 49-50mpg, 2 up or solo, I would imagine a 800 to be similar.

I'll sure be interested to see how that intake work turns out. I imagine when you're done you'll post a thread in the mods section with pictures and supplies and all? Or maybe you already have - but I didn't see it.
Or maybe open up an Ebay store "Troll's Drifter Mileage Plus Intake Kits". $99.95

- March 10, 2012, 08:09:53 AMWell, I have been tinkering with a new intake system to replace the stock airbox, and it seems to have made a big difference. I made a backing plate out of lexan to test the idea. I'm pretty happy with the results, getting almost 49 mpg on a run I have done many times where I was lucky to get 43...I'm going to go out this afternoon and try it again. The weather channel is predicting 60+ degrees, but a 30 mph south wind, so I'll only get a good reading in one direction. Oh well, at least it's warm. From the very beginning, I've gotten low 40s at interstate speeds, and even less in bad weather, so if I can get 45 @ 70, I'll be pretty happy. One thing I noticed, and I'm sure I'm not hallucinating...since I put on the high flow air intake the exhaust sound is louder, and has a bit of a "crack" to it...This is certainly an effect of more air in the combustion process..

- March 09, 2012, 23:27:04 PMWith gasoline on a run-away train to $4 per 4 quarts, let's talk MPG. Between the 800 and 1500, I'm assuming the 800 will get substantially better mileage. Can anyone quantify what the stock fuel mileage would be, on the 800 and on the 1500??? To make it somewhat "standard" let's say easy riding, flat ground, not heavily loaded.
Now, how about you tinkers, what do you expect can be easily obtained with cheap/easy mods to increase MPG? Troll, I see you talked in other posts about some efficiency mods on your FI 1500. Let's say fairly easy, readily available stuff like pipes/air filter/ tuning etc, and not including something like custom computer programming, or CNC custom intake manifolds, or anything real radical. I'm guessing +5 mpg or something smallish??
Have a great day.... God is good and spring is coming....
