1000cc Fuel Economy - I have searched for this!

[bimotabob]

Hi,

On long flat straight boring main rd's I can get excellent milage if driven at say 120-130 km/h average speed - 300km per tank no probs.
Did Hamilton to the mount and back for $20 last w/end.
That's on my old school injected FZR1000 powered bike.
Like any big bike it can and will use a lot on twisty roads with heaps of on/off throttle (acceleration)
Bigger engines can be still comparable to much smaller ones on the open rd's as they handle the weight easier.

Cheers

120-140km/tank - on the RG500 = 25-28mpg plus 2 stroke oil. OTOH, it is never going long enough under it's own power for it to actually use a tank. The Beemer gets twice that...
Your bike seems thirsty - is it in good une, no stuck floats, etc?

17 km per litre commuting and about 20 on a long trip for K3 SV1000

05 R1 About 220-230 till fuel light comes on. Getting around the 15 kmpl

1. Fill up Tank.
2. Ride for 60 minutes @ 85kph (don't tell anyone).
3. Fill tank again to see how much Fuel you have used.
4. Baffle all on KB with how economical your large bike is.

Hell, I have tried that and my fuel consuption went from 15.5 km/l to only 13 km/l. Probably because at 85 km/h I cant get above 4th gear. (actually I did it at 80, but that is close enough).

Similarly, many large capacity bikes will not be able to use top gear, and will be well away from their optimum fuel usage revs.

my previous 2004 cb919 ,and one im riding at the moment gets 280km+ highway riding and 220km -/+ in the twisties (has aftermarket pipes too

Ditto on my Hornet 919 - stock pipes. The fuel light comes on at the above figures.

Your ZX is extremely thirsty - do you realise that the red area on the tacho is not the economy mode?

[Highlander]

I do 17Km/l on my 750.
Was on a trip up North in September and was interested to note one of the guys (2 up on a Ducati ST2) was matching my fuel use to within 100ml each time we filled the tanks.
Noticed a similar thing with a guy on a Triumph Sprint (1050) on another trip.

Not quite a thou (only 937ccs) but I've averaged 14.6km/l over the past two and a half years (50,000 kms) on the RF900R.

????? that seems low

i get 15.5 if im giving it a workout up to 18 if being nice

i do a lot of 2-up riding also

have you modified yours to bigger jets, etc?

[Ixion]

SV does 16 to 18 km per litre , about 200 - 220 till the lights starts flickering on, no idea how far after that.

The GT750, on the other hand, caned, has turned in 6 (yes, six) km per litre.

Yes. High performance carbs off the Manta Ray RF.

I'm also a fat bugger with a ham fist.

at least you're honest

any idea what sort of horses/top speed you're getting now?

[WRT]

Around town, light goes on on the RSVR at around 150-160k's. Open road, even at a reasonable clip, the light wont go on until 200-220k's. Round the track . . . maybe 90-100k's? Fk all, anyways. That's on an 18l tank, I think the light comes on when there is 3l left.

When I had the TLR, I got similar k's to a tank, but it was only 17l. Most I saw out of it was 240k's before the light came on, all open road riding at just a fraction higher than keeping up with traffic speeds. Round Pukie had the fuel light on at 90k's.

pure speculation of course, but somewhere around 110-115 at the rear wheel probably. Most RF's do about 105 at the rear. It hasn't changed it as much as you'd think, especially when you add the extra cost of the gas.

I've knocked out the baffles on the zorst to try and lean it out, and I've noticed in a back to back comparo with ManDownUnder's RF that I am a bit down in horses at the 4000 rpm mark but more at full throttle.

Kinda defeats the purpose of having an RF I guess, but you gotta love that full throttle urge. I could swap out the cams with gixxer ones, and advance it even more, but you're pushing the law of diminishing returns there. New camchain, new gears, new clutch would probably be needed at that point. Not to mention the stress on the rest of the motor. Interestingly though, the valve shims haven't worn in 70,000 kms!

Its not quite as quick as a workmate's worked GSXR1100 with Yoshimura cams and exhaust and Flat Slides, but its still fast enough to get you well over the legal limit in respectable time.

As it's the daily ride I daren't expose it at the Sprints so again I'll speculate. It's probably good for 250 flat out. It doesn't take much to get up to 200.

I dont get it

my old trail bike did 250 km and then you need reserve
my 600 gsx did 260 km then you need reserve
my 1200 now does 270 km and then you need reserve
it has a 20 litre tank and theres 4.4 litres in the reserve
so im guessing about 330 340 and your dry

do you all have little tanks or something
