[Discussion] Technical - Fuel Consumption

o rite...

[NoobVtec2]

Hey guys, my current sprocket size is 15f and 44R. Before that is 15f and 45R. Notice that after i change my sprocket my fuel consump drop till 18+km per litre. Was 20+km per litre. I thought rear sprocket lower size will increase fuel consump? I already changed eng oil,wash k&n filter recently. Riding habit still same,tyre pressure pump regularly too. Only tin is 10k+ km already but haven't change my denso iridium sparkplug, will sparkplug affect fuel consump?

[IceZ]

Did u open ur vtec recently or pillion smone?

mayb spocket size realli affect..coz i ever heard wat fatdi told me...but 4get liao..keke...anyone plz help him..n me too..lolx

[ValenYono]

Smaller Rear Sprocket, slower pick up, but good high end. If always on highway, this is a good choice.

 

Bigger Rear Sprocket, better pick up but compromise on top end speed. If do urban riding with traffic lights and all, then this is a good choice.

 

NoobVtec2, I suggest you open throttle smaller by a bit, might help. If not, then suggest u change back to ur original setting.

[NoobVtec2]

hmm... i still can't figure out why my bike fuel consump sudden drop.. sianz

[AmmoTyr]

1litre = 22km

For me.

 

310 - 320km

See the petrol meter running liao.

 

SHELL - 95

 

Travel between : 80km - 100km

Hardly use VTEC.

 

 

Not sure abt my trye pressure ...

Maybe pump 240 / 280.

And travel between : 80 - 90 to see if i can save more petrol.

sorry to touble u guys again .today i just pump my fuel tank to full ,after some calculation my bike 1 litre petrol can only go abt 18 km.is it high consumption ? or normal.i riding a spec II.

18km / 1 litre

[Kinetic]

for me 22km/l, travel 100-110, 60% highway 40% roads, sometimes on VTEC, singapore esso 95, 60% with pillion

 

with grounding 3pt and yoshi. original air filter.

for me i notice 130km will drop first bar, 200km left 3bar, 300km left last bar, 340++ reserve..

 

hope it helps.

[Metalmarine]

mine, 19km/litre, Ver S... full tank b4 reserve = 300 to 310. Super high consumption for Ver S.

[Kinetic]

u ride fast n drag alot issit?

[Metalmarine]

I seldom ride fast, normally expressway only 90km/h. But my bike jus so high in FC. Headache also.

[Flaky_Boi]

Riding on expressway(90kph) consumes less petrol than on normal minor roads....

[Kinetic]

kaoz.. seldom ride fast yet so high FC.. maybe u wanna see a mech abt it..

[Metalmarine]

went to check, but discover nothing, but the only thing they mention was it may due to my last tunning that tun to more of high combustion or high fuel intake. I also dun know. So i jus do with it lor, hmm......

[Kinetic]

ok.. no choice then..

[carbin]

:confused:

hey guys... i sumthing to ask... my dad is riding my spec3 now.. n he's complaining the petrol consumation is very high.... like every 200++ kil he needs to go top up... which i heard frm my frenz tat it is not possible.... :help:

[Flaky_Boi]

Impossible..... All S4s r able to go til 300km++.....

 

Or does ur dad drag the gears??? Idling speed high???

[Allan82]

Has it reach reserve yet a not??? and ask him hw much Litre did he top up?? maybe he top up 10L only??? full tank is 18L leh. when the fuel guage blink, it would still be able to go up till 50-60 km more. hope this helps.

[andyann1]

Just in case it is not a simple case of topping up too early or low gear dragging, it may be good to test ride the bike yourself just to make sure the bike is ok and safe to ride.

[Guest NPNT]

calvin,

 

go wif Allan82's recommendation. mite be this case.

mine too. can't reach 300 as well. now it's abt 285 and left w 1 bar and soon enuf the blinking is going to start. usually try to stay at about 6rpm or below. at times, i do cross over when am rushing for amber light or i need tat power to pull away fr cars but usually a very short dist only.
