bro..maybe like what manzz said..try not to open ur vtec den change gear..if best....1st 3 gear change below 6k and change fast...den u can have ur speed too if i wasnt wrong..for s4 due to close gear ratio..think no need to drag too long b4 a gear change and also notice most other 2B mode bikes pickup rather faster den me too....

always change gear at 4k-5k rpm... tried till reserve nv open vtec still the same... Tried travelling below 95km/h also the same... definitely not wrong riding style...

Mine is the version "S". Not been sending to mechanic for carb washing and tuning for about 1 year 2 months liao. Currently, petrol consumption still stable around 34~ 35 km/ litres. So...version "S", "R", Project Big one.... if you still have them, is still value for money. Spec 1 and 2 , 3 engine is not the same design with the former and the petrol comsumption might not be as good lor. That is all for my input and observation so far.

 

So in case you happen to spot a second hand bike with version S or R or even project big one.... the price is reasonable.... is your grab. Good luck.

vtec oso can get a FC of 35km/l with the condition that u ride not over 60km. figures is got from the manual.

 

mayb ver S can ride around at 70km or 80km to get that mileage??

 

 

 

but to b frank, those older versions is the save fuel type of S4, economical i should say...

 

 

 

cheers...

hey guys, jus to share some info.

 

basically, stock air filters offer less airflow, thus less power. aftermarket airfilters offer higher airflow. higher airflow means richer Fuel/Air (F/A) mixture, which means better power, but only to a certain point. when there's too much air(when airfilter holes become enlarged), the power output reduces. same thing applies when there's too little air flow(when airfilter get clogged up).

 

ie to say, K&N / BMC filters do help with FC, but only to a certain extent. ultimately, it's how you ride.

 

jus taking my own bike (vtec 1) as a case study:

 

when i jus got my bike, was changing gears at 5k rpm, crsuiing speeds at 90. FC was 320 hit reserve.

 

then change to 4k rpm change gear, 340 hit reserve

 

then change to 3.5k rpm change gear, 360 hit reserve.

 

now i change gears at 3k-3.5k rpm, dun drag on lower gears, dun open vtec (in sg only)

 

present record : 390 hit reserve, tank emptied at 468.5km (i was only bout 50 meters away from the petrol station!)

 

anything below 3k rpm, it'll be damn slow in pick up. i'm not saying my method is the best, but it works for me

 

that amounts to 26km/L.

 

and i found out that still works for cruising speeds up to 100km/h.

 

try to travel more on highways if u can, it'll help in fuel economy, cuz moving off and idling (due to multiple junctions) takes up more petrol

[Mussolini]

for me (vtec 1),

 

i change every gear at 3.5k rpm until 6gear

 

i ride 80-90km/h constant. at times, ride 100km/h-115km/h

 

simei-->>sembawang-->>simei (daily)

 

best milage: 385.6km still got 1 more bar n reserve. total fuel 14.2l

 

i noe it's the wrong method of calculating cos i dun like to ride my bike in reserve

 

fuel consumption: 27km/l(everytime)

27km/l???

 

i oso wan!!! :cry:

[episode2]

mmmmm..lets put it this way...if bike is properly done up for FC economic..think it will have better mileage...best is to tell ur trusted mech and see what is happening...

i would say if we do regular maintenance or change watever wear n tear item, FC greatly depends on riding style liao.

 

 

[hongwei09]

Was just wondering which bike actually have a better fuel consumption. I noe it depends on various factors but i would just like to know in general which bike is more economical in terms of fuel consumption.

I'm ridin a spec 1 ....

 

Last sat go jb fill petrol V-power abt 12l full tank liao .....

i got in abt 223km .... then the fuel meter start between one bar and flashin ... so i assume its goin to near reserve ....

dat means i average abt 19+ km/l

 

i jus top up 3liter jus today ... wan to see wat mileage i get this time before i go into same scenario like above ....

 

I travel frm woodlands to changi daily roughly about 27km if not wrong. ANd i estimate 1 bar of fuel is abt 3 liter (if is true full tank is 18l exclu reserve)

 

Will update when i get my experiment result back ....

[Flaky_Boi]

Huh???

 

Who voted for Spec3??? whahaha...

Got vtec how to save petrol???

I'm riding spec 3 but consumption like very jia lat... 320km go into reserve le...

[Flaky_Boi]

Yep~ I guess u r 1 of the throttle happy riders...

320km not jialat le.. How bout Spec1 260km reserve liao.. Whack or not whack still 260km+/- reserve.. :giddy:

[anakin]

how come ur spec1 so jialat? hit reserve at 260km? how old is ur spec1 le? or u always open vtec is it?

[CrossOver]

Dunno lei.. FU plate my bike.. I send for full service, wash carb everything at my regular mech and retune also still the same.. I seldom open Vtec.. Dun wanna drag too much my lower gears at the major rd.. At expressways, nowadays with the speed cam, TP and all, wanna go 110-120 to open vtech clear some carbon also dun feel so safe...

Wah So Much Ar... You Got Always Whack ?

[stkoh78]

i agree that ard 320 is realy good enuf le .........

but to hit 436 before hitting reserve....hmm.........really no comments le...

[cookie_monster]

For non-vtec version to hit 370++km b4 reserve wif normal riding speed(90-100) is jus a piece of cake...

 

i ever clock 390km b4 reserved a few times, but i thk its not accurate cos suspect one of e plugs faulty causing irregular combustion... but on average abt 370km b4 reserve, no problem
