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

[Ultima]

Hey guys! Hope this thread can help me with an issue that I'm currently facing. Pardon as this is my first time posting a thread!

 

My Super4 had an oil leakage at the top block that I did not rectify the problem for months due to a health condition. I was then told by the mechanic (I prefer not to name the shop so as not to create any bad name for the company) that the parts in my top block/engine are in really bad shape due to the leakage that I have to send it for an OVERHAUL. And I was quoted a price of $6K plus.

 

Is this the standard price for a CB400 overhaul? Any shops to recommend?

 

6k sounds alil' too expensive.. try checking with other shops

wow 6k... unless your machine is super new, i recommend you selling the bike, get the cash and plus the 6k for downpayment to get a new bike even more worth it.

 

if $6000/10 to change all piston and top block maybe still ok lol

6K..faint..faint..faint..can use $3k downpayment and installament for a new bike of get another Vtec with 5 yrs or more COE left. Your problem is just head gasket blown. Just changed that and don't agree to change or service anything else. Should be $160 to $180. Extra cost comes from they say this change that change especially Vlaves, Shims, seals, etc..NO POINT IN DOING bekuz its an old bike..here new there old..nothing works properly together and sooner of later..it can get worst than instead better. So..just find a shop to have the head gasket replace.

Hi guys like which version tank gt fuel lever?

[wywsyy]

version S have

[newguy]

Need recommendations on shops that does knocking tank back to shape. Dent my left side due to self skid..

Hi guys, anyone knows the reason why during idling, the voltage can go up till 14.0v , but during acceleration the voltage drops?

 

I have already changed magnetic coil, rectifier & battery..

 

Riding spec 2

this is normal... 14v shows that your battery is in good condition. when running voltage should be constant at around 12.4.

when low battery it shows around 11.4 when idling

Hi bro, thanks for replying

But over time, the voltage I see when I first switched on the bike daily, it seems to be gradually dropping..

 

Any idea if it could the 2-way spy alarm causing this, or something else?

when you first switch on the voltage is usually not the same. as long as it stays around the same range then it's safe.

 

i can't say what voltage everyone bike should be at as each bike might not show the exact voltage reading due to different wire installation location and different accessories on the bike.

 

an indication of low battery is when it shows near 11 when you just turn your key.

as a reference, my lousy voltmeter lowest voltage reading is 11.4 any lower it shows 0 volt. initially i thought my voltmeter is gone already but on a morning around a mth later i cant start my bike hahahaha.

But its kinda strange isn't it? Its like the battery isn't charging while accelerating..

actually you can't really tell if the battery is charging unless you connect your voltmeter directly to the battery. most commonly (i can say 99%) of the time the voltmeter is connected to the headlight wiring which means it is only measuring the voltage drop across the bulb instead of voltage of the battery.

 

 

also from what i know, when your rev goes higher than a certain rpm most of the power goes to your spark plugs instead of for charging of battery. if i'm not wrong it's 5k rpm, someone please correct me if they know the actual rpm.

 

if anyone is interested, i can take a simple video of my voltmeter and upload here. (when switch on, when engine is running and when reving)

Can i check why my IU is not detected when i pass through eps or erp?

 

when i start the bike it shows a reading, low batt. but it cannot detect when i going through EPS or ERP.

 

TIA

I've heard of cases where the new slim type iu unit drains the batt over some time.. or maybe a faulty iu / just a weak batt? Maybe......

Hi guys,

Need some help here. My spec3 when running at 60-100 can feel something ticking. Initially, I tot is my new tyre problem. But when I close the throttle, it stop ticking. It keep ticking whenever I open the throttle. Anyone know what happen to my bike? Thx...

it happens only at 60-100? is your vtec open when the ticking happens? what about your check your engine oil level?

[NormanMusa]

Hi guys,

 

Urgently need help... any idea where i can get super 4 VTEC 3 engine lower casing? its NOT the part with the chassis number. its the other one.

[Blue83]

Oil level is ok. And vtec not yet open

[Q]

 

hi guys, i just got my 2A and was looking for super 4. can someone tell me what is the diff between super 4 spec 3 and super 4 revo?

and which model is better? as in which 1 will have lesser problem? and maintain of bike which is cheaper? pls help.

Hi guys =)

 

I have some this question about the bike because I'm really new to it and it's troubling me. Please kindly guide me through. Thank you.

 

1) when I'm riding on 3th gear around 40 - 50km/h or 6th gear 60 - 70km/h I could heard this weird sound. I don't know is it a whining sound or not. But it sounds like the buses we have here. When they accelerate there's this like turbo sound. I could only hear it between this two gears and speed and only when I open the throttle then I could hear it. What's is this weird sound?
