Fuel comsumption (ZX6R NINJA)

just bought a 99 ZX 6R ninja , any ideas how far it will go on a full tank of fuel???

[kev]

About 120 miles before you hit reserve I think.

i have a zx6r 99 bike also

i normally get around 110 miles...the hit reserve, best ive had from reserve is 27 miles (i reckon i had about 2 miles worth of fuel in it )

it really depends on riding...best ive had is 130miles then i hit reserve

regards

Hmmm. I must be doing something wrong - I've had 180 showing before reserve (although it is downgeared so thats probably more like 150).

I got 60 miles out of my last tank of fuel (with 2 zx6r's )

16.5 litres to fill up again - somebody work it out as I can't be arsed

although I didn't think it was too bad considering what I was doing to it

[Visitor Q]

i have had my latest bike about 10 days and i had to fill up AGAIN, so far ive put in about 50 quid. Its a bit depressing compared to a 50cc. What is the best way to keep fuel consumption down, revs or speed? I am trying to ride predominantly at 6k rpm for a bit, see if that helps, and smoother braking and accelerating (less fun, but im a poor student, save the heavy stuff for when im rich -/the occasional time a ped boi in a nova starts revving at the lights etc-). But ive been told the carb might just be fucked and putting in a shite mix, especially since;
it doesnt idle worth jack
revs randomly droop on occasion
sometimes riding with choke on makes it much much much much smoother
when you stop fast (ie back coming up) it stalls
amazingly bad petrol consumption
poorer perfromance then apparently should be acheiving (fastest ive had is 95mph ish, whereas should do 110 reasonably easily)


oh well

If it runs a lot better when the choke is on, then the bike may be running very lean, so the choke richens the mixture up and runs better.

You'll be wanting to get that sorted, think a carb clean and re-jet is in order.

Shouldn't be too much hassle to fix though I doubt.

Ste managed something like 190+miles before reserve when coming back on the M1 doing 90mph ish.

Hi

I would expect the Goose to be fairly good on fuel, but then you are comparing it with something that was very good on fuel!

Some bikes do seem prone to stalling when you brake very hard to a standstill. My RS does. Suspect it is the floats in the carb getting confused under braking, but never worried about it.

In theory the engine is at its most efficient on full throttle with the revs at the point of peak torque and in top gear.

In practice the wind resistance will mean that the bike is going to be wasting a load of power keeping you at that point, while loads of other factors will also come into play.

Also in reality it will depend on how the engine is set up. EG, a bike with an accelerator pump carb will use a load of fuel when at low revs round town, when the throttle is being opened and closed a lot. A slide carb will work badly if you just give it full throttle at low revs. A CV carb should sort it all out itself.

Only real advice is to try and keep it smooth, and to sort out your carb so that it does not have some of its more dubious habits.

All the best

Keith

I'm no expert, but if it was already running rich, then putting the choke on would just flood it and the engine would cut.

Judging by what you say with the choke improving the ride, then it sounds like it's running lean. But I don't know if that would make the fuel consumption really poor, as you'd expect the opposite, so I'm not sure really, but sure Keith will step in and help shortly

<EDIT> I is psychic! He got there before me, didn't I say he would? hehe nice one Keith </EDIT>

Hi

to Yams. The choke will make the mixture richer. However exactly how it works will depend on the design of the carb.

But, idle mixture is controlled by different parts of the carb than the mixture at full throttle, and changing one will have next to no effect on the other.

All the best
