Filled up the Norton on the way to work this morning after a 200 km spin on Sunday....its only got a 10 litre main tank so was running low.....
It took 7.9 litres to fill up
Thats 23 litres per KM or 57 MPG in the old money.
I can't say I was trying to be economical, just the weather was wet and cold.
Pretty impressive what old tech can manage on gas....you can stick your fancy fuel injection...Amals rule
anyone else squeezed good mpgs out of a 750?

My bonnie would be doing about that,,but never bothered working it out.
Most of the older 500-750cc twins I've owned have been pretty good on gas,,,so long as they weren't two strokes that is,,,because some of them were not that good at all,,,friggin' Kawasaki triples.
Used to get an easy 50+ out of the T500 but caning it got down to 33mpg. Running at 50mph on hot plugs and trying real hard got 70mpg! Not bad for a 2-stroke twin.

I used to get 50 mpg out of my Suzuki GT750, riding fairly gently. but the very best I ever got out of my Kawasaki H2B was 15 mpg, that was on a trip Ch-Ch to Hawkesbury , in the company of a KL250, doing 80 kph the whole way. I was impressed, normally round town the H2 would return less that 10 mpg.About 5 mpg on the race track!!
Fuel injection really doesn't have much advantage in outright fuel economy over carbs in outright fuel econuomy due to atomization. What it has an advantage in however is always being able to meter fuel mixture precisely for different air density, whereas carbs have just one fixed setting and if you want to make small adjustments for altitude then you have to do it manually. Nothing wrong with carbs for fuel economy.Originally Posted by Voltaire

...Full throttle till you see god, then brake.
Just done the math and, averaging 39mpg out of my 1340 Hayabusa .
I reckon that's pretty good compared to a Kawasaki triple
Regularly get 75mpg from the Trophy and similar 65 from the Guzzi...
I must be getting old (although I doubt it),but I seem to remember getting 100mpg out of 650 Triumphs no problem (on twin carbs,single carbs got less) and 95mph out of my 600cc Norton,and 95mpg from a pre unit Tiger 100. Of course these were real gallons from the pumps,not converted gallons on a computer,and it was just the shitty old fuel from back in the day,not this modern high tech fuel we get these days.

Seen the one on TM at the moment,,,$6000,,hell I'd like another one of those things,,,but not at that price.
L82Y,,,,odd thing to remember after almost 35 years aye.
Yup. L82Y for low speed like town running then swapped in L78's for open road.This quote is hidden because you are ignoring this member. Show Quote

C'mon lets ride....
I get around 45mpg out of my lard arse CX. Mind you it's done over 160,000ks so there might be a wee bit of wear in the carbs and the like so not really too bothered with it.
Out of interest oil consumption is around 1 litre per 1000kms.

My C50T would average 60mpg, getting down to 58mpg two-up with all our gear and not riding particularly for economy.

I seem to remember routinely getting 65-70mpg from my AJS 650 and about 70-75mpg from my Matchless G80S. When my Honda C50 Cub is finished I'll have a crack at the claimed 0.6849 L/100 km; 412.4 mpg!
I'm stoked that I almost always get 50-55mpg from my CB1300.

Retirement with a cause
Worked over CB400 / 4 single cam , it was 220 Kms from my place to Waiouru and at night was a worry with no 24 hr gas stops open after Paraparaumu. 14 litre tank and i just --- i mean just made it if i tucked behind a truck or 2 to get a tow for some of the Bulls North road. I had topush it at least 3 times i remember and after that was fine as the next stop was Turangi and all the way to Jaffaville.
