Does this seem a little low?

[Breed777]

Done 2 trips to town now and maybe a dozen starts/warm ups etc.... totalling 60km and have 2/3 of a tank left on my 88 GSXR....

Is this about right? I have no idead what fuel econopmy I should expect from a bike.... from this I estimate 180-200 km from a tank, sound right?

[Slyer]

It's a 250 right?
Expect a bit better than that for inline 4's and even better for twins.

[Breed777]

yeah its a 250.... spent a bit of time just starting it an letting it idle too...

What should I expect from a full tank? how many kms....

Also who uses 91 and who uses 96 0r 98?

What should i use?

[EJK]

180 to 200kms sounds normal for an old inline 4 250.

And use either 91 95 or 98.

looked on the net.... the GSXR 250 has a 16L tank with a 2 L reserve....

Depends on the capacity of the tank, dunnit...

My SVS (650) does about 350km on 17 l tank before I panic and refill it. Would go about 375 before running out. 21 - 23 km/l (60 - 65 mpg). I use Force 10 from Gull.

In one of the other posts on this forum, other guys were getting 20km/l from their GSXR's.... thats around 360km.... how can I get that kind of mileage from mine?

Have you filled it right up and then let it hit reserve? If not then do that and see how far you get.

Depends on the condition, state of tune, type of riding (and where).
Best bet is to fill up completely and go for a responsible ride at a steady speed on the open road with as few hills etc as possible. Whatever mileage you get, you can probably cut that in half for round town or fanging.

ok, will see how long this tank lasts me..... currently....60km and 2/3 left

[sharknet]

I guess it all depends on how you ride.

RF900, 21 litre tank. 200 miles to fuel light on, 220 miles, engine stops. Switch to reserve and lost my nerve at 256 miles (411km) Put 20.5 litres of gas in. (All on open roads/motorways.)
Currently using Gull Force 10, stops the pinking.

Does your bike have a fuel gauge or are you just looking in the tank? And are you riding around town or out on the open roads? In your original post you said you only had 1/3 left now you are saying 2/3 which sounds a lot better. From what i understand you should get at least 200ks out of a tank and could get up to 300 if you ride it nicely.

ok heres the stats.... filled bike up when i first got it.... used it for about 12 rides, just round the car park kinda stuff.... Now done a couple of short in city trips... totalling 70km all up and now sitting on half a tank of gas (according to the gauge).... this doesnt seem like much.... bike sits between 5000 to 7000 rpm round town.... is this normal?

This morning had done 60km....2/3 left
just did a 10km trip to take her to 70.... now only half left....

Seems pretty thirsty?

Thanks guys

Don't trust a gauge. And peering into the tank won't help much either. Start with a known (full tank), take note of the odometer or set your trip meter, ride until it needs to be put on reserve (splutter, cough, die). Only then will you know what it will get out of a tank.

[Badjelly]

now sitting on half a tank of gas (according to the gauge)....

...meaning it's probably somewhere between 1/3 and 2/3 full, maybe. Petrol gauges aren't that accurate, at best, and yours could be past its best.

Get some more accurate data before you start worrying about this. Start with a full tank (filled to a reproducible level) run it to nearly empty, fill it again to the same level, and calculate the consumption in km/l or l/100 km.

I reckon you'd expect 20km/l = 5 l/100 km or thereabouts.
