Fuel economy for a GN125?

[ducatilover]

You're not getting confused with its oil useage are ya?

1L/100km of the thick stuff

You should change lube type

I thought about that, but naaaah, big bore kits are more interesting.

It will be interesting to see what the fuel economy is like on your RS250.

lol...

economy?

yea I won't be keeping an eye on the mileage for that thing, I don't keep tabs on the amount the race bike drinks either... we never seem to get anywhere. just round and round in circles

I'm getting approx 5.5l/100km on my Gixxer 750 commuting Raglan-Hamilton, though it does use a bit more when I decide to open it up a bit...

I've hit reserve after 90k on my DT..... Just love throttle abuse on 2t's..

Suzuki NZ.... The GN 125. You could expect around 30 to 35 km/litre of fuel usage, doing around the 90km/h on the open road.

Wow that’s a lot of replies thanks guys!

So. Turns out, I just fail. Epically.
I thought I was out of petrol, but I was only about ½ to 2/3 empty. -_-

So my bike is pretty good on petrol… Yes, I do have to rev it to no end, and so that will mean it is using more petrol than it needs to be using but meh. That’s life right?

Is there any easy way to tell how much petrol you actually have? Apart from the ‘shake and look’?

Turns out I wasn't even filling it up properly either. No one told meee....

Most people tend to use the trip counter as a fuel gauge. my 400 is on reserve around 240kms so I fill up around 200-220. After filling up reset it to 0 and repeat.

There will be numbers out there for roughly how many KM you can get on a tank before hitting reserve. Or if you're particularly brave you can find out yourself. After that it's simply a matter of making sure to watch your trip counter and filling up before it hits the magic numbers.

Short of that, the only method is open it up and have a look inside :P

Ride bike to petrol station:
Put on center stand.
Fill tank
Reset trip meter.

When next at petrol station, not how many km it has done and how much it costs too fill it to the brim.
The GN has 9L before reserve and 3L of reserve, you should easily see 200km before reserve (My '04 was getting around 180km to reserve, but I rode it at full throttle, everywhere, whereas this one I've topped up at 220km and it wasn't yet on reserve)

May be (another) stupid question... But. Here goes... Is there some particular way to fill up the reserve or does it just fill when you fill the normal tank?

Most people wonder about that
The main and reserve tanks are one and the same.
The fuel pick up for the main tank is set about an inch higher than the second pick up (reserve) so there's no need for two tanks.
Hopefully that makes sense? I could show you with my spare fuel tap, but I imagine it's a bit difficult to see that far

Don't listen to Doug, he's talking shit. There is a special way to fill up the reserve, no good having it if it is empty when you need it eh! What you have to do, is flip the valve to reserve (chances are if it needs filling it will already be set to reserve), take off the gas cap, and insert the filler nozzle pointing as far backwards as possible, I find standing in front of the bike an putting it in 'upside down' is easiest. Now on the GNs the reserve fill valve often gets stuck, so you have to tap the tank as you are filling it up. I find a good tempo for this can be achieved in sequence with aiming the nozzle left and right a bit to ensure it fills, so repeat out loud, "left, right, left, right" etc, and with each word swap direction of the nozzle and give the tank a good thump.
Then when the tank is full, put the cap back on, switch the valve over to normal, take the cap off, and fill the main tank.
