spec 1 is 18L.. mine 380 before start blinking..

wah bro power your FC....can share your drin=ving style.....me most of the time 290 - 300km reserve liao......

[liuj0008]

haha.. my fren spec 3 also ard that range. I change gear ard 4 to 5 rpm.. i seldom open vtec.. i travel on the expressway most of the time, cos my house near the exit then all the way till i reach school.. think the fuel consumption better when u travel on expressway. i usually maintain ard 100km.. haha not sure if it explains

erm 2 things that can make ur fuel meter blink... 1 is ur bike at side stand... the other 1 is u suddenly pick up very fast then it blink.. wanna get best measurement is put ur bike straight and wait for few mins... it will increase

ya but i try a few time already...\

but still same result...

erm any1 noe's spec1 full tank how many L ?????

 

btw mine FC 18km/L....... (no open vtec)

tried downgrade mine petrol frm v-pwr to 98, change EO, put dunno wat magnet(to increase mileage), pwr abuser 2 ......still e same =_= when i bought tis bike ower said he juz tune his crub......

spec 1 fuel tank is 18L including 3L reserve.

 

FC for a vtec model shd b around 20km/l + or -.

 

mayb u wanna try to change ur spark plugs, air filter? or even service the carb if u can afford it at a go?

 

riding style do comes into picture. if u like to drag abit during move off, then ur FC will definitely b higher.

380km then start blinking? after calculation, its ard 25km/l. quiet unbelieveable for a vtec model. ver S is a sure can hit this range.

[swat_]

bros.. prob my FC si bei jialat.. do carbs still presist leh.. mine 230 start blink liao, try ride relax oso same what else? jettings? which shop can do jettings? do what?

[f3nG]

mine is oso ard 360 before blinking.

currently riding a spec 3.

stock bike.

i tink its my riding habits bah.

im always the slowest in moving off at traffic light !

haha

don't drag gear and faster change up to higher gears

den slowly throttle to 80-90km/hr.

vtec seldom open.

read from a CAR magazine highest gear and 80km/hr

is most fuel efficient.

don't noe if it works for bike.

 

my 2cents bro

correct me if wrong.

hope it helps

[dintigger]

mine, 280 blink blink liao .. then about 330 to 340 empty liao.

riding habit not good, always about 7k rpm, change gear at 6k rpm and bike always heavy load.. i fat mah .. then plus wife more jialat ... that why every 3 days go 2nd link pump...

Plz la.... how can compare 4 piston and 1 piston.... Btw super4 is 1 of the best f.c in terms of 400cc... 290km blink is still alot better then rvf... 230-240km reserved... No such thing as want the power but scared F.C high...High Input High Power ... Low Input Low Power ... cannot tahan go back to krr... still alot cheaper then super4 cheers

agreed.

 

mine was 300km(15litres) when blinking.. normal city riding, vtec sometimes..

 

after some time, needed more power.. so tune till 260km for 15litres.. but for cruising only abt 150km - 160 km per 15litres...

 

gonna change back already.. or you can try playing with the spockets for better FC..

 

you cant have best of both worlds:

 

GOOD PICKUP = POOR TOP END

GOOD TOP END = POOR PICKUP

 

GOOD FC = POOR POWER

GOOD POWER = POOR FC

 

BUT if you try to play ard with your jets, spockets, riding style, etc, you'll may find one combination that will suit you best.. it'll take time, but no harm trying..

[Sonicgear]

Wah u tune until ur petrol so jialat huh.... play top speed or pick up??? i feel my bike no power need to tune back... but f.c quite good 320km with dyno and full system ride like crazy....but feel the bike pick up can be better....

[biting_point]

bro, must rem i got 3 H&B boxes.. no load already quite heavy, with clothes, spare parts and stuffs lagi jialiat..

 

i tune to pickup, i think now must tune back to top end for touring.. very siong if keep pumping petrol.. if can achieve 200+KM for touring at 150-160kph, i satisfied liao..

 

city riding hopefully will go back to 300KM..

Bro i got a brand new bike and its like drinking petrol way too much.... i used it for abt 3 mths... its a spec 3. My bike fuel gauge when it left one bar, i top up abt 13.87 litre of petrol, with that amount of petrol i covered 217 km.

 

Let say full tank 18 litre, my bike can go only 281 km. so 1 litre of petrol i can go only 15.64 km! Im using sg v power, riding style 100 km/hr to 120km/hr average, once in a while wack the bike.... I dont drag my gear so high.. issit normal guys?

 

Anyway im using ngk iridium plugs and pipercross air filter, maxima ultra, rest of it stock condition.. As for the precondition check of the bike, all in tip top condition.... Tyre pressure, chain slack, all maintained regularly..

 

Bro out there, i need ur advice... Should i sent my bike for a tuning? Aniway its a new bike, wats wrong? Im happy with my bike, its just the petrol part dats killing me!

 

Today i just pump shell 95, i goin to see how it fare... Keep u guys updated!

[CruSheR]

wow ur fuel compsumption really very low. my bike oso 3mths old my fuel is about 360km for 15L my bike is still stock. if ur bike is from boon siew 1 i think let ur baby go for checkup

[cashwong]

wow! 360 km for 15 litres! Tats very low..my consumption is high also..roughly 20km/l......haiz..

Seems like you like to constantly open vtec and thus the high FC...

 

Btw, what's your front and rear tyre pressure?

[f3nG]

yeah bro seems like u open vtec too often liao

probably tat explains why

 

erm aniway i tink v-power kinda gets drained fast

dunno its me or happens to the rest too

[seancxm]

which RPM do u change ur gear(s)?

[skateboy]

pls take note that vtec series, FC of 20km/l to 22km/l is normal. of cos more than 22km/l is a bonus. below that, shd take note of ur bike already.

 

cheers...

[ahda85]

my onli clock 18km/l jus went to pput my main jet to smaller size now trying the fc

[keeok]

maybe u should try tuning ur carb... that is where i noe how much petrol and air to mix and burn... juz suggesstion...

[h_LoNg]

Its is not something wrong with the bike that cause the heavy fuel consumption. Its your riding style.

 

100 - 120km/h is ur average speed

So i can assume once in a while u will wack til 150km/h at least.

 

It is known for a fact that once your vtec kicks in, the bike will drink petrol like noboby business. At the speed of 120km/h, a Super 4 will drink more petrol compared to a bigger bike like frazer 600.

 

So either lower your average speed or change to a bigger bike to get better petrol consumption.
