Fuel Consumption ...

[What?]

Some quite interesting figures shown here, but most of them have no relevance to the question: what should an early 80's 1100/4 be drinking? Twenty years of technology plus aerodynamic fairings have made a huge difference. Still, it is nice to see that sort advance quantified in some way other than HP / top speed.
BTW, my F650GS (injected) gets an easy 23 Km/l. The old carburreted model only did 18Km/l.

[What?]

But.... 'what' would it do if it were to run on GlenLivet or Glenmorangie?

About $18,000 per Km, I should think

I have finally worked out what my old bitch is doing .... I took a quick blat over to Wangas and back and took a careful check of how much I used and the distance covered .....

The equation worked out with an 11km/lt result ....This equates to roughly 220km/20lt tank.... how does this compare with other bikes of the same age and size ??? I'd be interested in your feedback. Bear in mind I haven't had the tune-up done yet and she is in need of an oil/filter change.
Also the average speed was around 112kph with me doing the one way trip in just under 40mins .... left at 7pm .....a little drizzle and no wind !! Bloody awesome ride with almost nothing on the road after Sanson !!

My old GSX1100E used to give me around 13 - 14 km/l, so I suspect that you could probably get a touch more out of an EF. My current GS1200 gives 17 - 18 km/l and is based on the same motor, just a bit more modern.

I've figured out which buttons to press on the calculator and come up with- wait for it - 16.5k/l for my 1989 GSX-R1100 (it is xJapper so translates to about '91NZ) The CB500 did about 7.5k/l *shudder* which translates to over double the gas in exchange for about half of everything else

I had a 1974 CB500/4 with 610cc kit in it - that was one seriously thirsty mutha. Used to ride L/Hutt - Levin a bit in those days (1977) That is about 100k one way. Bike had a 3gal tank (13.5l). If I rode it hard I could empty the tank each way.

Total was 3.1 Imp gallons or 14 litres. Reserve was 0.9 of a gallon or 4 litres. giving 2.2 gallons or 10 litres on the main.

[MSTRS:Me]

But wasn't there a about gallon in reserve?

Don't remember - would you want to test at 20mpg?

Praps a little unfair on the CB - it could 'pin' the speedo needle - past the 200kph mark.

The EF is based on the earlier GSX motor not the alternator behind the barrel oil/air cooled jobby.

The old XV gives me 17.3Km/L I may as well be riding something bigger....
