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

[Ah Pek]

can i ask Yuasa YTZ10S-MF and the 7A wat the different.....

 

and as well as the price?

 

n oso is it a muz to change the rectifier n battery together?

 

The difference is CCA (Cold Cranking Current) and yes, you can use. Selling at Chiong Aik for $160..but elsewhere can get $145. It's direct from Japan and a dry cell..no need to inject electrolyte...'plug and play'.

 

Rectifier change with battery?..no..unless your rectifier is screw. Check for consistance 13.b vdc from output of rectifier to verify.

[Ah Pek]

i have someting to ask for the battery -ve if there is like white wax surrounding it is consider wat?cos now mine bike cant be start.

 

Sometime soon..your battery is gonna go. Those white stuff are sign of electrolyte leakage due to your terminal point where it join the battery is cracked liao.

Hi guys, need to ask some question about S4. Im quite new with this so i hope there are some out there that could help me. So here goes...

 

1) Heard that Vtec1 has some problem with rectifier. Is it true? Or some other S4 model that has that kind of problem. How much does it cost to repair it?

 

2) Heard/read about S4 owners doing 'grounding' on their bike. What does it do and if its good how much will cost?

 

 

3) What other stuff can you do to make S4 ride good again, let say if its been running almost to its COE life?

 

 

Thanks in advance. Cheers...

Knowing so many Vtec 1 owner..never heard of such..only first series of PB1 because the rectifier does not have cooling fins. Cannot be repair..replaced instead..$65 to $95 depending from where China/Japan.

 

2) Heard/read about S4 owners doing 'grounding' on their bike. What does it do and if its good how much will cost?

 

Grounding works great for better sparking thus better combustion and oso helps return leakage current effectively if done correctly. This does not work with what has been called "points grounding". Cost among all the mototiam varies from $30 to $75 depending on how its done. Careful..many are useless and done more harm than good.

 

3) What other stuff can you do to make S4 ride good again, let say if its been running almost to its COE life?

 

A lot can be done to bring your ride back to "live" again..thru just "Liquid Engineering"..if interested..pm me.

tks ah pek...will be heading to buy battery now..hope that there is shop open toda

[greenruby79]

Tks Ah Pek....for all your insight. Hmmm...'liquid engineering'. Sound interesting. Will PM you soon about that.

Quick check with you guys.

 

The odometer and speedometer on my super four version S isn't working anymore. What could be the cause? Would I have to replace the entire set? Any indication of the approximate price range?

 

Many thanks in advance.

From what I understand..the whole base electronic base circuit board has to be replaced..cost about close to $380-$500..can't quite remember, base on a Vtec 1 model from FJT quote about close to a year ago. If I'm not wrong, the board come with the LCD display panel all integrated.

 

Check with LAB...they are bringing the stuff too at about half the cost only.

(Q) i was wondering how do we clean our chain properly:) ?super4 bike,the chain and sprocket if possible

[Ah Pek]

(Q) i was wondering how do we clean our chain properly:) ?super4 bike,the chain and sprocket if possible

 

20% soap water..80% kerosene (won't harm rubber rings)..and a brush to dip in the solution to brush off. Jsut about any oily surface..even carbs area where there might be oil stain acculumated with dirts from donkey years.

 

Rinse off hard with ater after that. Go for a ride..get the chain dried and oil with eo. Have fun!

"so fuel addictive is good for old and new bikes ? " No!..can be humful depend on what you know what's good and right. Please, don't asked for produc detail here..ain't promoting their products in case someone uses it and it screwed their bikes. There are procedures andinstruction to follow.

Nothing secretive..if at all interested..come meet one of those Ko-pe-Orh session at Tech Ghee square. Check outcome from Non-Vtech threads.

@@ realli can be humful ? nvm i already order from him .... do i need to take note of anything ???

[eement]

ah pek i already change the battery already but start after a while, the bike feel like not fuel going in sia...

 

the ting is like muz left the bike quite sometime b4 the bike can be start again...same ting happen yesterday night....

 

but yesterday i took out the fuel line and crank start, there is petrol coming out from the vacumn

I was generally refering to using any kind of additive that some can be harmful...not whatever you have ordered etc.

 

But do some research before jumping into a product that suppose to ehance your bike. Some items that use by car cannot be use on bikes.

Could be or may be the vaccum tube is loose due to oversize at their lips before entry. Its probably being starve off petrol. Just check those things that are fuel feeding related in function and u should be able to narrow down the problem. Check for cleaniness of your air filter too..or take it off and crank start test. Could oso be you choke linhage..give it a few pull from the right side on atop the outer carb nearest the side, outside. It could be 'jamming' the flaps inside the carbs.

new bikes not neccessary.

i prefer STP addictives

another prob now ...... my rear brake pad seems thin and not effective, so i went to change my brake pad @ a bike shop somewhere near my place (didnt what brand of brake pad) but the brake still no effective.... bike still moving very fast , while i step very hard on the brake ......

 

i go back to the shop , the mech said that it because the brake pad is smooth type , he dont have the rough type =.=

 

all i wanted to know now is , if its realli the brakepad prob ???? or is there any other parts of my brake system spoilt ? have check my brake fluid still full

[shellshox]

Hi bros, sorry if i post wrongly here, but anyone know if a Super4 frame can be converted to cafe racer? Have not seen anyone doing it here...

LOL!...what I can tell you is that your mech does not know that the back braking for S4 is designed that way in order not to lock the wheel but still can if you step real hard and sudden.

[eement]

ya that true...u wont wan a good brake for the back...imagine if it lock...

 

 

Ah pek wan to ask u someting, the flowing out of the petrol izzit related with the fuel cap?cos i wen to wash carb toda n the mech check still got the slow fuel flowing problem...den he blow the fuel cap with air gun and try again den ok

 

izzit really cause by the fuel cap?i dn wan to push mine bike again...this 3 day very suay liao

Yap..that's correct. There is a bleeder hole in the tank cap that leads to a small air bleeder tubing under the tank. There is a bigger one but that's for overfilled petrol to flow out.

 

Once the air bleeder hole is clogged with dirt or other foreign objects..or the tube under the tank get kink while putting back the fuel tank, petrol flow consistancy is obstructed...just like sucking a half boiled egg without another hole on top for pressure to pust stuff down.

but i totally feel nothing while pressing the rear brake , is that normal ??? even i press real hard .....

Anyway..there is no smooth or rough brake pad type..may be his hand was oil and oil soaked intot he padding. Go back to him and request he take it out again and use a ******* file and file cut diagonal lines pattern on the brake pad. If he don't, tell him you get into accident, you sue the mototiam..heee...x2! Oso check your brake fluid level.

izzit because its a cheap brake pad $18(he only have this brake pad "frm thailand") ? my brake fluid is full , i now thinking of going other bike shop to change back the old brand i used (goldfirend) just scare it might not be brakepad prob , most likely is brakepad prob right ? ^^ll
