So I wanted to lighten up the mood around this place a little bit and start a thread just for fun. Seems like there have been a lot of question/problem threads on here (which I have started my fair share), so I thought I would start this to get peoples minds off troubleshooting and worrying. I would have started a poll but I don't have privelage to do it.

So on with the question. Just for fun I thought I would ask what MPG you guys are getting and what type set up you have. Meaning what type carb, what size bore, and what year. I'm sure that everyone would like to know since the huge increase in gas prices.

I'll start:

Average 35 MPG. It's a 76, with a Mikuni VM38, and it's bored 10 over.

I can get close to 50 mpg on the highway most of the time. I've never checked it around town. 1983 XLX - stock bore - stock carb with larger jets, accelerator pump kit, choke plate removed - SE air cleaner w/K&N filter - stock header w/crossover, Dyno Power mufflers - 23/49 sprocket combo.

I have a 84 sporster bobber with a s&s carb I don't have a speedometer and ran out of gas alot and it seems to suck up gas when you don't know the mileage.

1977 with stock carb, bored .030 over, running a no name more free flowing than stock air cleaner backing plate and a UNI foam filter, and drag pipes. With one size larger than stock gear on the front, I get around 50.

Yah I suppose I should have said that mine was city driving. A lot of stop lights between home and work!

84 , 30 over , S&S super e , i toned down the jet size , and dont really remember what size right now because i have sometimers. havent checked the mpg in awhile , but the last time checked it was getting 43mpg on the hwy , and running at any speed over 70 you might as well unscrew the petcock and let it drain out.

The best I ever got out of the 'ol 900 was 50-mpg HWY at a consistent 60-mph.....S&S "B", stock "P" cams, 23-tooth front sprocket, mag ignition, ported heads (more like hogged out), Manley stainless valves, no passenger, a sleeping bag and sober.

I don't have a speedo either (although I'd like to have one), but more or less I get 50ish mpg. Which is much better than my car which gets 12ish mpg. I save several dollars per day when I ride my bike.
