Then something's really wrong with those numbers. They should reflect what the average Joe gets with those vehicles, shouldn't they?

true , but sales-tales maybe work ?

i actually beat the factory MPG numbers in my last tank on my ninja 250. they claimed 61 MPG, i got about 67.5 MPG. so yes, it is possible to beat the factory numbers. also, i wasnt even trying to get great MPG numbers, i was just driving normal. i dont really hot rod anymore anyway.

Department of the blindingly obvious

For the last year on my commuting Yamaha XT125X I had been measuring my mileage each week and seeking to adjust driving style etc. to reach 100MPG (imperial) and was generally disappointed with the results.

At the time to renew the brake pads I dived in with confidence and found that 3 of the total of 4 pistons were more or less seized in place.

I suspect that I had not noticed it because I am a delicate braker generally - altho the bike had just passed its annual MOT test.

Having freed off the pistons and basically serviced the calipers the ride was transformed and normal mileage rose from 71 to 86 mpg (imperial) with a new best of 91.

So, friends don't do an Andrew and assume that basics are OK - make sure they are!

My defence is that I am an old motorcyclist without much disc experience - my Ducati has Grimeca 1ls drums and they DONT DRAG.

hope this helps someone

Ps this Yamaha is a Malaguti-built 125 enduro style machine, so at least I have stayed italian!

i have seen that happen before. brakes barely dragging can really hurt your fuel economy. glad you got it straightened out. by the way, do you have pics of your duke? i would love to see them. older ducatis and laverdas are my favorite bikes.

Best mileage on my 1982 xj 550 Yamaha, turbo hybrid of my own design, no throttle valve (butterfly), runs on diesel or gasoline, fuel injected for both diesel and gasoline, with our own software design piggy backing a "micro-squirt" system, with many other devices of my own design.
On gasoline 105 mpg steady cruiz,
On diesel 127mpg
Available rwhp 108
Weight 423.16
Still tweaking system, further mileage gains should be available. Also currently building fairings.
Further tests will be done at an east coast university in December.

Huh. Do you have somehing more (an article, etc) about this one? This is something VERY interesting...

Your welcome to read more here: Energy Extraction
Gasoline mileage varies greatly dependent on what station/source it's derived. Unfortunately I wont be able to comment on this system much, what you see on the sight is about all I can tell you directly on the system it self. I will say it's pretty fun to drive.

I used to ride all the time... miss it! I may get into it again now!!

Wow! naturalextraction... that sounds like a great machine! You rn biodiesel in it at all? Does it run well in all weather?
