Mine is a 1988 nsr250. I just bought it. I added about 6 litre to it last time and it only lasted about 70 kms. Is it normal or something else is wrong?

Thank you for all the advices!!

Sounds about right to me.

6 litre=1.33 imperial gallons
70km=43.5 miles
= 32.7 mpg.

I did 202 miles yesterday of mixed riding, but haven't refilled yet to get the final figures, but here's a breakdown of a couple of the legs:

Exmouth to Great Torrington via Sourton Cross. This is 61 miles (98km) in total. Exmouth to Sourton Cross is 38.8 miles, mainly A30 dual carriageway and cruising at 80mph. Sourton Cross to Great Torrington is fast wiggly A-road. Top-up at Great Torrington was 1.5 UK gallons (6.81 litres). That means 40mpg (9.45km/ltr).

Great Torrington to Tiverton via Barnstaple, Lynmouth and Minehead is 90 miles (145km) of more mixed riding, some of which is very slow through some winding gorges and small towns, but 2/3 is fast sweeping riding. Top-up in Tiverton was 2.62 gallons (11.8 litres), meaning an average of 34.35mpg (12.29km/ltr)!

151 miles/243km -- 4.14 UK gallons/18.8ltr -- 36.5mpg or 12.92km/ltr.

Damn... I must be smoother than I thought!! Laughing

When I top up next I will add the final leg up, and get an overall total for the 200 miles. It will also be interesting to see what the averages are over only the wiggly bits! I reckon it will drop below 20mpg then.

And by the way, does keeping up the revs affect the fuel cost a lot?

It's even worse when you consider you are burning £10 a litre 2-stroke oil too! ROTFLMAO

Yeh keeping the revs up will burn loads more than pottering about. Smile
Probably 1/2 the fuel consumption if not worse.
But it sure is fun. Very Happy

It's not actually that much of a diffierence, as 2-strokes are inherently inefficient at low to mid revs...

Yep, high revs won't drink it, wide throttle openings will.

Like they say at the Ferrari dealerships, when you ask what mileage it'll make:
"If you have to ask, you can't afford it" Laughing

his can do about 20km/liter. His is a VMAX.

AND ? A Citroen 2CV can do 22kmh, but what fun is there in that ? Wink

The MC18's are less efficient than the MC21's.
