How many km per tank for my FZR250?

[Corbmyster]

Gday
I have in the last 2 months got a great FZR250 which aparently does about 200km's to the tank so I am told. (small?)

I am using octane 91 and was told by the previous owner it does about 200 km's to the tank. This seems a little low for a bike as cars often do about 350km's plus.

I flicked to my reserve as it started to die after 160km's just yesterday and because I usually fill bit by bit, I have not tested how long a proper tank lasts for. Its a weekender so I dont really take notice how much I actually use.

This seems a little low.

When using the bike, I usually give it a good squirt when I need to but, generally I sit on 6-7000 RPM in any gear as its just before the powerband and above the gutless zone in the rev range. I tend to be conservative when I ride. Being a 4 clyander which winds up alot

Is 91 the right octane for a 3LN 1990 FZR250?
lol do I open it up too much?
does 160 k's seem right to flick it to reserve?

Anyone with past FZR experience please help me out !:blink:

[RC1]

should get 250ks out or your 250 at least, if i ride at legal speeds i get 250ks fro my TLS, fill her up and find out is the best way IMHO

[prvoke]

i get around 23k/L on my 88 CBR250R, IL4.
pretty sure its at least 230km's before i flick reserve

[HornetBoy]

On my old hornet 250 i used to get about 180kms includeing reserve so that sounds about right for a FZR

[Corbmyster]

hmm.. CBR's are virtually the same motor right? Ill fill up and test it out on pay day ;)
How many litres is a FZR tank does anyone know?

says the tank capacity is 12 litres, including 2 litres reserve, so 10 litres between full and where reserve kicks in.

There have been several threads on this site about fuel consumption. 160 km from 10 litres = 16 km/l. That sounds poor to me for a 250 4-stroke, but maybe the old in-line fours are particularly thirsty.

[Corbmyster]

ouch thats a small tank eh?
ill definately take note how many litres the fuel docket tells me it has inside.

[humphrt]

I usually get about 300-350 out of my VTR250. Thats a 13L tank. So 23-27km/L, and thats not moving slowly.

my cbr250 gets 14km/l when im riding it normally and 16km/l when i ride it leagally.

[FilthyLuka]

Um, my GSXR gets 200k to 14 litres, thats about 14km/l. And thats a 750 four cylinder... The fire blade im currently riding does 190km to 15 litres, so 12km/l, and thats a 900cc four cylinder. Surely 250 fours don't guzzle that much?

But then again, they do rev thier balls off everywhere so who knows

I used to use 98 in my old FZR.

I used to get anywhere from 250 - 280km... IIRC on the fzr250.com they said it should be about 280km a tank

Daniel do you think I should be using 98 octane?

[Folcan]

I dunno I mean if it runs fine on 91 then dont worry I think.

mine didnt run as well on lower octanes well thats what it felt like.

besides 98 is expensive

I was told by a mechanic mate (who is very good, and incidentally works on Andrew Strouds racing bike), regarding fuel for my 1998 CBR250RR:

"never never never never never never use anything other than 91octane" - although i think he put in a few more 'nevers' :P

I made the mistake of telling him I was putting 98 octane into it.

His reasoning was twofold. (I'm paraphrasing these, as he gave a very in depth explanation to each)
1) The ignition timings for higher octane fuels are different, so you could potentially get pre-post ignition issues
2) 91octane is cleaner, so less chance of fouling the plugs prematurely.

He finished with:
91 for Jap imports - cars and bikes.
95 for the old Holden HQ with bench seats & Subarus ( i think he specified these because I have one)
98 for performance vehicles that would normally run on 95.

Of course theres alwayst he exception to the rule ;)

[Corbmyster]

never? are you sure ??? haha got it thanks:clap:

It feels smooth thru the gears so like you say with the timing of the ignition - its not like my corolla even on a good day (which is a good thing)
hey that's done 250,000ks and its a hand me down so I aint complaning if it rains!

[2Slow50]

Hey mate,

I recently sold my FZR and was using 98 in it.. I agree that when I had to put 95 in it, the bike ran somewhat smoother.

I found that I was roughly getting 160/170kms out of a tank of gas, so from my experience you are doing alright...

[Wet]

I have owned a FZR250 and I was lucky to get 160kms out of it. I ran it on 91,96 and 98 all with about the same consuption/efficiency levels. Biggest thing just give it heaps and regular oil changes.

Great little bike, but I know what you mean about the power slump. At about 116kg I had to get everything out of each gear to keep the wee thing pumping.

Cheers.

[Corbmyster]

What spec oil do you recommend? Dad has some oil for his offroader and I have no idea of what that is.. but I heard from a friend to use semi-synthetic.

Its due for a change I reccon.

Next on that list is to replace the chain (and possibly sprocket)... Those darn registrations keep them costs up! It doesnt help being a student who also owns a car. My finance is getting a spanking at the moment!:spanking:

Thanks Wet for your input!

That is a bit low. Get your carbs cleaned / tuned / re-jetted?

I get 200 km out of my CBR's tank before I hit reserve, usually.

[Corbmyster]

How many litres is your tank? I worked out that before Reserve, I have 10litres. Then 2 on reserve.

Curiosly - are getting carbs retuned expensive? like my dad is a mechanic who has tools to dismantle anything, would the bike mechanic need the whole bike or could I save if I got specific parts out for them to play with?

As said above, I am a poor student :P

[YAMASAKI]

i used to get between 170 and 180 Ks on a tank before hitting the reserve, the FZR tank is a lot smaller than the ZXRs. If you've ever taken the cover off it you'll see what i mean, the top bit(which is normally the tank) is purely a cover. i used to run mine on 95. jap imports were tuned to run on higher octane fuel than vehicles intended for the NZ market. I doubt whether you can even buy 91 in Japan.

I don't know how big my tank is, but costs $20 to fill up with Mobil 98 after doing ~210km.

Re carbs - You have to take the whole bike, maybe do a rolling road test etc. It'll cost you a few bucks.

[Wet]

I used castrol GPS for my oil. Not a fully synthetic but good quality. Maybe check air filter, tyre pressure , the usual fuel economy draining stuff.

Possibly get carbs looked at but as you say see how the cheaper options go first.
