hi guys...need help...does pumping v-power instead of 98 petrol harm e engine?? heard someone saying b4 tt v-power nt gd for bike engines.. pls help....my bike always pump v-power

[dingjc]

hi guys,

 

if i open vtec at times, goes up to 130 on expressway, i calculated my milelage, appears to me only 18km/l. is it normal?

 

at times if i dun open so much can go 20-21/l. can anyone pls advise me pls?

 

cheers !! (:

[eement]

it still ok ba

 

that normal ba

 

constant speed bring out the highest mileage

[mka_t_s]

i just bought a super 4 ver S. The milage i was getting was 16km per liter.

so i decided to service my ccarburator and even changed the needles...

now i am still getting 16km per litre.... what should i do....

[B.e.n.s.o.n]

Hi guys, my mileage on my spec 1 is around 21km/litre.. reasonable

dose any1 has a yoshi fs on spec 1 here? tot of getting one but worried about the fc sia... juz went for petrol last night... almost $30 for 14 litres... (@_@)

[MonoWorld]

my spec1 FC is around 21-22KM/L.. the best i have achieved was 23.5KM/L

 

touring FC ard 17-20KM/L

there a lot of thing effecting the FC

 

see ur chain spocket n other need maintainance part

true. tyre pressure, float needle etc etc will also affect ur FC. but most obvious is the constant flow of the throttle.

hi guys,

 

i am doin my research on super 4 to see if its within my budget to own one. so far after reading thru threads on fc, a spec3 would give between 20-23km/l izit? can some1 confirm with me? what about spec 2 and 1??izit the same or better?

Spec 2 FV Plate

Full tank + Reserve = 320+ to 360+

Daily To and Fro Bukit Panjang - Kaki Bukit (Peak Hours)

Route of order - Dairy Farm ->BKE -> PIE -> Exit enous link

 

BKE Jam towards PIE Changi Airport

Traffic towards KPE before paya leba exit heavily congested

Heavy traffic at enous link

 

mixture of smooth and regularly brake and go periods

Milage of bike : over 100k

bike status: hardly maintain but constainly check tyres pressure weekly 34/36 PSI

Petrol: Malaysia Mainly Mobil F1/ Ocassionally Caltex / Rarely V-Power Racing

 

Riding habits do play a part in bike petrol consumption

My habits

High Rev in low Gear(change gear between 5 - 6k RPM : 70%

Change Gear before 3 - 4k RPM : 30%

[bluesurfer]

so normally 320-360 would means that your fc is ard 19-20km/l ar...that is ard the low range of super 4 ?

[jazky]

i would usually pump around +/- 17 litres

usually around +/-32 - 34 RM which is RM1.92 per litre

i usually go malaysia when reserve starts blinking

when the reserve starts blinking the safety distance u travel is between 50 - 60km if u based ur bike consumption at 18 - 21 km/litre

Reserve tank should be 3 litres if i am not wrong..

[jazky]

There is a lot of Super 4 on the road.

I am not saying about my spec 2 is one of the best ride.

my is a cheap ride, transport to point a to b

 

My personal views are:

Spec 3 are always better than Spec 2.

i think fc depend on how u ride too?

 

expressway i open vtec often, my fc only ard 18-19~

 

and if i dun i can get 21-22~. rmb most rider will say their ride is good rite? (:

low range of s4? cannot say like dat one

a lot of other things to consider than juz riding habits eg. rider's weight, whether got pillion frequently, pillion's weight, tyre pressure, atmospheric conditions (riding at night gives better fc than in d day), street/highway riding, carb setting n even type of petrol used if i'm not mistaken.. n d list goes on

 

for me i tink 19-21km/l is quite alrite.. anytin LOWER is stil ok....... PROVIDED u tompang a baby elephant, rev ard d red limits for every gear for d whole full tank..!

[bluesurfer]

oic...thanks for the advice...cos now i am riding a 2b bike fc is good. but the jump is huge if i upgrade to a s4.are all 2a bikes getting this range of fc or s4 fc is not as good as other 2a bikes?cos i was expecting like ard 25km/l for a 2a bike.

[Sixer]

get a version s if u want 25km/l.

 

my previous ver s can get me 27km/l. current spec 3 max is 23.5/l.

U might want to take a look at those chopper type 2a bike which have a better FC as their engine normally rev at low rpm...

engine rpm plays the most important part in relating to fc in my POV. normal 1.6L car can get FC around 12 KM/L for normal driving (My frined's new Jazz get 18 ), imaging it's engine capacity 4 times a s4, weights 1.5t plus, yet it still get FC more than half of us, why? cos car's engine normally rev below 2k

yeah man.. if cars were revving at 6 or more rpm n cruising at 4-6rpm like most bikes do... then.....

dun worry bro.. for d power, u'll soon get used to it.. great power comes with great responsibility.. hehehehe

[MrKan]

is it true that Spec 2 eats more petrol then its younger and older brothers of the Vtec range??

[noryhan]

no la... i dont think so... should be the same mah.. both using carburetors mah... see la if previous owner has done any modifications... usually its due to modifications that coz this problem..

[MrKan]

for those who have full systems and their fuel consumption is still like 22-24km/L. How do you all do it?

[MrKan]

spec 1 yoshi full system, knn filter, kenso jet kits.

 

Full tank b4 reserve is 328km.

 

Change gear at 3.5-4 rpm. Cruise 80-90km/h.

 

Play with pick up a little. Open vtec for pick up like 3 4 times.

 

Comsumption around 23km/L

[AkalaPovic]

just curious , issit possible to get the mech to tune back to ur previous settings after u do carb tuning lol..

 

I riding sp now and just did tuning my fc also become damn horrible leh.. scare the **** out of me. last time normally 24 to 25km/l then now suddenly drop to barely 20..

 

although the engine response and power is alot better at my low range now
