[Discussion] Technical - Fuel Consumption

[thechosenx]

so to check it i have pumped to the max, i just check if it overflows on the floor? cool. thanks.

 

If i'm not wrong, the super 4 manual says pump till you hit the metal part. There's this 4 piece of metal the catches the fuel cap, if your bike is upright the pump till the front metal part. If is in side stand, pump till it reaches the right metal part.

 

Not sure whether you can get what I'm saying.

just 1 to know who are seasoned with touring,so ez-er to hv chat on riding matters ,especially those who ride at least 3000km per mth at m'sian h'ways....i did tour spore-KL-spore almost every week with my wife as pillion,datz d reason i ask here fr those who ride CB400 of any version do like i do..

 

Used to be like you bro..up and down Sg-KL (my wife was taking her degree there)and many other parts of malaysia..clocked almost 40 000kms on my s4 per year toast my piston n cylinder block on the second year of the bike..changed to a bigger cc bike coz i find its less stress on the engine and parts.. On s4,160kph is about almost 10krpm but on a blackbird its only about 5.3krpm...

 

But dunt get me wrong on a cb400 engine durability i've a fren who own a vtec 3 and basically clocked more than 200 000kms touring and working ,no top overhaul done,engine still running right,not burning engine oil and only changed a waterpump at 150 000kms..

Semangat bro! My wife also took her degree there at uia. But my dad in law (her dad) would venture instead on an st1100.

i dont whack my bike, only open throttle to get pass slow cars and filter

Your Moriwaki too powerful

Hi,

some doubts with revo? Heard that if it always hit the reserve there will be problem with the fuel injection? Is it true?

Not that i know of. I always hit reserve. Had an injection issue but solved after i've sent it for injector servicing. Shop recommended to do it at 40k interval. I did it at 60k.

[Baal]

yep I heard about that too. Not just bikes or revo, even for cars. When fuel sensor cant sense.....= problem. Just matter of big or not so big $ spent. Not to mention fuels at low levels, heats & stresses the fuel pump for EFI also. When that goes.....also big $. For my car with 45 litre tank, I usually try to pump when theres balance of 1/3 tank. Leave 15L inside to cool & not stress the pump. For bikes unless u NSH going straight line, u will lean here & there when u make a turn/corner. hence if ur fuel level is low, imo would increase the chance of "fuel sensor/pump/injector" issues.

 

For S4 with 18 litre tank, imo best not wait till reserve. balance 2 bar I will pump liao. I assume 1 bar approx. 3 litre. So 2 bar = 6 litre ( balance of 1/3 tank).

 

Think its total of 6 bars for the 18 litre tank?

LOL.

 

i sometimes can get 18 to 20km/L

 

really depends. just that the last few pump i monitor, avg 18.x/L

Yours is Mori full system? ( Mori only have full system isit?)

 

Did u also do high flow air filter + piggyback ecu/dynojet so as to maximise the entire rev range & eliminate flat spots/vibrations & such ? Thanks.

ya the shorty full system.

 

i did nothing to the engine. no dyno or whatsoever

 

air filter is K&N.

 

i got no complaints for the fc la, i work got $ pay for petrol ma haha

 

just that i keep see ppl with 20+km/L i jealous!

 

[Baal]

But if urs spec 1 ( >10 years old) + full system + KNN, 18/litre is expected. Natural aging. When my bro in law Spec 1 during 2003, completely no mods about 21/litre. Do u get vibrations & loss of torque at low-mid revs ?

no vibration and loss of torque

 

if there is, what could likely be the problem?

Wont say something wrong but will be due to loss of zorst back pressure. In ur case, since no vibe increase / loss torque at low-mid could be coz ur saved by the Vtec. which is also a gateway controlling back pressure by 8 valve operation

[tasrif03]

Major headache, what if your FC doesnt reach 200km??????? Tyre pressure all ok, riding btwn 90-110km/h on average. Btw riding a spec2..

 

Can it be due to leaking inside??

Maybe your prev owner meddle with the carb jetting n ect

Apoke to prev owner, his mileage was abt 240-260km before reserve. When i bought the bike,mileage was about 250-270 before reserve...nw, hardly 200km with reserve... :/

Check your air filter, Spocket size, wheel bearing, tyre pressure

Just have my knn filter washed. Dammit dirty. I guess its the filter that cause my Vers to drink so much petrol. 18km/L leh

Hope you got better FC now after getting the k&n air filter washed

Really prays it will. Else cub or piston very expensive liao
