4 Cylinder Fuel Consumption Question

Anyone know roughly what fuel consumption one could expect on a 20 year old
Jap 4 cylinder bike? Also is there much difference in consumption between
twin and 4 cylinder bikes of the same engine size (cc's)?

 

If ridden to maximise economy, you could expect something in the
ballpark of 20km per litre.

My 1987 CBR1000F was a bit worn and smokey, and delivered about
17-18km/l on the open road (and about 10 in stop-start traffic).

My 1988 GPX250 averaged about 22km/l, dropping below 20km/l once it
had 130,000km on the clock.

My 1985 GPZ900R gives about 19km/l.

My 1986 BMW K100RT gets about 11 kilometres per litre.

Sidecar?


BTH

 

Yep!

My '87 K100RS gets about 15-16 km/litre,

My 1.5 vs your 2.0 HRD

I never get anything like that!
On my XJ900 I generally got about 15kml highway and 13around town.
The XJ750 was markedly better and it and the 900 Trump get about 15 local
and better on highways (but the XJ750 does it on regular ULP!)
All of these figures are decidedly NOT "ridden to maximise economy"......

 

My GSX1100G with 2.0 HRD gets about 11.5 km/litre.

My CB1300 is routinely averaging 17.5-18 km/l. I guess it never has to
work very hard to go well.

What sort of traffic?

In Sydney stop/start the Norge gets between 15 and 17 km/l, but on the
open road it gets 20 or better at 110-120kmh. Does drop at higher
speeds though, and riding "spiritedly" with the revs over 5k for any
length of time will see it getting 16 or so.

My XV750 gets about 13-18Km/l (city-highway). Never seen any better than
that, though, the jets are worn to the point that it runs rich enough when
cold to never ever need the choke.

 

Same for mine, except that my commute is country riding with half
being 100 km/h limit or higher, so I get 20 km/l on the commute.

And I forgot to mention that my 1967 CT90 gets about 40km/l on the
open road (at 65km/h).

Since we don't really know what engine size we're supposed to be talking
about I may as well add these.
I recall going 52Km on a KLX300 and using about 1.9l of fuel which was
roughly 26K/l.
My GT250 gets about 22 on commute which is a few km of 50/60 zones.
I've gotten 29-30Km/l on the 250 previously but that was a country trip
... mostly at 110Km/hr.. or so ..

 

Remind me what your bike is? I don't recall seeing any V8 trikes at
the unaugural (although there was a trike at the Ruptured Budgie with
a suburu forrester engine and transmission).

52.5 at my local servo in Gordon (or 48.5 with a ticket).

You get 4c discount from Supermarket receipts on gas? Only valid for
Petrol in WA. don't even give it on diesel.
