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

[tiku]

hi guys, ytd encounter a weird problem with my bike, when i riding, the speedometer will suddenly 2 sweep and den on and off den all my time all these are resetted.

Voltmeter recently shows a decrease in voltage when throttle, but when i didnt throttle there is no problem, speedometer wont off and on by itself. Bike still working all right.

 

Is it problem with my rectifier or magnetic coil?

 

from idle , u rev , as rpm goes up, voltage should go up.. if it goes up and then drop, coil issue...

Hi i recently just upgrade to s4 version S.

Hi,

Congratulations for owning a good bike!

Btw, this topic has been discussed before. You gotta search this forum for the answer from old posts/threads.

 

just in a nutshell,

1) S4 is a 4 stroke bike. no need 2t for normal use.

2) coolant flush every 12 months - no longer. if just bought, flush now.

3) tire sizing is different from the spec versions - yours is 110/70/17 front & 140/70/17 rear

- tire pressure is about 200kpa front & 250 kpa rear

4) engine oil is 2.7 litres (or 2.9 litres with oil filter change)

5) if I'm not wrong, your sprocket sizing is 15 front and 42 rear.

- lube it once in awhile. I suggest you use x-ring chains.

 

as to whether this will be done on servicing? well... you gotta specify what you want la... cos usually a good mech will ask you service "what"?

 

 

just my $0.02

Using pivot voltage stabilizer without grounding. Not really much diff to me.

Hi Guys, I just started riding again, and just brought a CB 400 Spec 1. I would like if anyone can advise me about the charging rate of spec 1, cos i have just install a voltage meter and it showed about 14.5 to 14.8v at idling speed, when accelerates it when down about 14.5v. Is it okay?? or is it overcharging??

 

Pls advise, Thanks in advance.

Batt, rectifier, coil all change and even the starter carbon also change but no bike got the problem of no starting again. When power on, and I try to start, there is this "tiag tiag" sound, but bike not starting.

[thechosenx]

Hey bros, need a little help here. My speedometer suddenly not working, how much is it to change a senor? I'm riding Vtec 1.

 

Is it something common or needs to order? I hope it doesn't cost a bomb..

[HaiR1]

Yes , they do sell in Sg

 

 

But it is Totally useless to fix it

 

 

Reason are:

 

-it trap heat (instead of getting rid of the heat AWAY from the engine, u are instead Trapping the heat)

-cosmetic add on

 

 

If it was good, why don't the Honda Genius make a Cb400 that way when came out from factory?

 

 

 

 

Well, just my advice.

 

 

End of day, it's your bike:cheeky:

Thank you for your reply Hair1 and I totally respect your answer, and you do have a point... Im pretty sure it's just for looks. Do you know what the name of the shop is that sells these things?
