[Q&A] SBF CB400 Official Q&A Thread 2009 (PLS ASK YOUR QUESTIONS HERE!)

[HaiR1]

Hi all, today was riding as per norm then suddenly the engine light on the top left came on. Orange in colour. I stopped awhile and continued riding after. Shortly, the speedometer did not work, but the tachometer still is. I also noticed the idling went down to 1 instead of my norm which is 1.5. Anyone encountered this before? Much appreciate in advance for your inputs.

 

Bike which spec?

Dear All & Rider,

 

Thank you for reading. Sorry for highjet and have a good day.

Somepart have left over in the store-room and did not clear off when sell off the bike.

 

CB400SF*:

a. Brake pump only for Front wheel. Bought form Car/bike Scarp industrial located at sungei kadut, as my pre S4 brake no function very well, I thought is the pump spoilt, so buy one thinking to change. At the end is brake pad worn out. Bought at $60, sell it at $30 for people who need it or for replacement.

b. 1 Pair Original S4 mirror, take out form my previous S4. Sell it at $30.

* Take all at $55.

 

All above selling price is FIX, i already give my best offer.

 

Thank you for reading, and if interested, you can reach me at 81022843 by call, SMS or whatsapp.

Hi all,

Are the rear sprocket dimensions for fitting the same on NC39 & NC42,

As I want to change to 42 teeth, can only find NC39 sprockets in England.

Thanks Ken.

Hi, i have been riding for super 4 spec 3 for quite some time but i dont feel the power of my vtec. what could be the possibilities? my view of vtec i assume is when it is on, you will feel a sudden "pull back", correct me if i am wrong.

The Vtec cut on feel of a Vtec 1 and 3 is different..Spec 3 is more mild and gentle and that's suppose to be an improvement. If you want better performance..get the right Eo and do a proper grounding...you get to recover 3-4 horsepower depending on your current bike conditions.

Hello S4 bros, I have two problems with my super four and would like to ask if anyone encounter similar experience and what are the fixes.

 

Problem 1: When starting my bike, the headlights turned off by itself for a few seconds and turned on afterwards by itself. Both low and high beam all ok. At times, the lights won't turn on thus I need to turn my bike off and then on again.

 

Problem 2: My temperature light indicator turned on by itself and then off again when my bike is on the move. Coolant is still sufficient and fan is not on.

 

I do hope S4 bros and orang lamas has solutions to this. Thanks in advance bros!!

problem 1: off for sec and on again is normal when you start your engine. after your engine is started no light, your ignition button is stuck. happened to mine to. i just use my finger to flick it and the light will be back.

 

problem 2: you have to go to a shop and let them determine what is spoilt. if can be your fan and/or coolant pump.

Hi bros, thanks for thr reply.. For the headlight I've yet to check them and for the temperature indicator light problem I've experienced an incident which explains the event. While riding earlier, the coolant rubbery tube thing burst and splattered on my feet (quite hot in e beginning) and after that the light was not on at all. I conclude it is due to choking in e tube.

Hi guys,any good shop to recommend me for carb tuning? It will be great if its at the west area

Does wrapping ur end can makes it rust? i've read it somewhere someone advise against wrapping ur end can as it will eventually rust the end can itself...anyone know its true?

Hi bro, I went FJT and bought the bulb replacement for DIY. After changed, realised it's not the bulb issue. Normal and high beam no light but flashing can. Wire issue? Thanks and have a nice upcoming weekend.

Check your wiring loom inside the headlight

If ur right side switch assembly is very old or have cracks on the ON/OFF see-saw toggle switch..tape it up and open the two half partially up (via 2 small Philip screws under it and spray some WD40. Do the same for the horn and headlamp ON/OFF switch as well. If this does not help..could be wiring connectors not proper or wet in the headlamp.
