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

[jayz]

Haha Jayz, for me right now the low beam has been okay for me already. Sometimes it doesn't on only after i press the ignition the low beam comes on liao. Could it be low battery? Because I saw the forum guys say spec 2 when low battery, when on the bike the meters & rpm will spin twice? I dun think spec I have bah..

 

i just change my bulb then ok liao. $15 for the normal h4 type.

It is not the bulb problem la lol, normally shop do this to earn, else if they quote u $10 to fix the wire u will also dulan so might as well sell u one bulb to let u have the 'at least i spent $15 on a bulb' feeling haha, which bike shop u went to?

Hey guys,

 

My bike feels sluggish in its acceleration during the 1 to 4k rpm range. There is something like a engine boost at the 4k rpm range, and the bike feels more responsive and powerful after the 4k rpm, something like a delayed acceleration. I am not sure why this is so. Air and oil filters, spark plugs, engine oil have all been changed recently. Could the problem lie with the carburettor?

Likely to be ur carb, perhaps can try send it for a wash and tune? Hopefully is better after that

Nothing to do wif ur carbs.

[Ah Pek]

Care to enlighten?

 

"Air and oil filters, spark plugs, engine oil have all been changed recently"..air and oil filter has nothng to do with it. Plugs ok and eo depends. Could just be ur clutch biting point and change slack. If ur carbs got problem..it's across the board from low rpm to high..no such think as 1-4k rpm.

[Ah Pek]

Biting point and chain slack no problem. Can I tune my carb to get better low-end power to solve this issue? Will that sacrifice higher-end power though?

 

Never heard of carbs being tune for such..its normally tuned for correct air/fuel ratio and adjust for synchronisation among the four. You may want to only adjust the idling to at least 1.5 (when engine is hot) for better "pick off"...assuming ur idling now is too low like 1-1.2k rpm.

Ah Pek , my Showa oil liking .......

Market price 2hand is how much .....

Bmc and k&n filter which one better for V2 ...

 

Ah boy jln besar sell bmc $68 and k&n $55, how to comfrom

Which one is original can check ?

Outside sell bmc $110 and k&n $95

Ah Pek help .......

For ur Showa..I assume u talking about back suspension..go to Teck Thye No.12 Bradell road..look for David and have it rebuild at $240 for botrh units. @nd one should set u back about $300 to $350 depending on conditions.

 

There is no such thing as which filter is better..all Hi-flow does not give u better performance as claimed (IMHO). No doubt they does specified filter of air and provide faster volume flow to contain ur air box capacity...the carbs setting for air is ALWAYS fixs. You decide. As for pricing for these stuff..sorry bro..not into the business, can't say much or tell the difference..if u need an answer, all I can say is "can use can olehdee lah".

There is no such thing as which filter is better..all Hi-flow does not give u better performance as claimed (IMHO). No doubt they does filtering well and provide air faster in volume flow to contain ur air box capacity...the carbs setting for air is ALWAYS fixs. Its only valid when u need more air/fuel ration when you modified jetting. For routine commuting..its useless..but perhaps the advantage is that they are reuseable. You decide.

[haider]

Ahlo ! guys , i need some parts, the engine cover for the right and left side. i know the left side is the magnetic coil cover not quite sure what the right side cover is called.

 

I also need an original pair of signal lights.

 

Stupid hit and run is a blow in your pocket.

[sk8free]

issit possible to change the stock exhaust on project big?

self spray not easy... recommend you go shop do... crash bar only shouldnt be too expensive..

 

Easy lah, bro. Only consideration is whether or not you have the space to hang the bars after you've painted it to let it dry. Now is not a good time to spray, by the way. It's been raining everyday so will take longer time for the paint to dry.

 

Just undo/loosen all the bolts on the crash bar. If any bolt is difficult to undo, spray WD40. Leave the bolt that is attached to the chassis nearest to your seat to the last. Remove U-bolt first at bottom. Then remove the front bolts. The crash bar will now be hanging off the bolt near the seat. Use your knee or leg to balance the crash bar as you undo the nut for the last bolt. Crash bar is now off the bike.

 

Repeat for other side.

 

Use sandpaper to remove the old paint. Use 000 grade sandpaper for fine/smooth finish. After removing old paint, wipe with a damp (not wet) cloth. Let it air dry for a while.

 

Steal a clothes hanger from your mom. Cut it to fashion a "S" hook so you can hang the crash bar from the hook. Make the hook about 5-6 inches long so you won't spray your hand when spraying.

 

Spray time: Use S-hook to hand crash bar from one of the bolt holes. Use the one which was nearest to the seat so you can spray the rest of bar more easily. Start spraying. Most important point about spraying is to follow instructions on the can on how far the can should be from what you are spraying. Keep moving the spray can over the crash bar as you spray. What you want to see is very fine droplets on the surface as you go along. If you hold the spray can too long in one spot, the paint will be too thick and will start to drip. Spray as even as possible. Best finish is to apply one light coat. Let it dry. Spray a 2nd coat. Then spray with clear coat if you want to finish.

 

Have fun!

hey guys,

 

had a mini accident a couple days back. i think i can DIY all the damage cept for this one part. the speedometer (only the speedometer, not the RPM meter) gauge is sticking out of its socket. the big screw that holds it in place to the housing behind the headlight has come off together with the gauge. anyone know where i can get this fixed at a reasonable price? any help will be appreciated. thanks!!

[corporatemanthras]

Oh and im riding a VTEC II.

UM can do it

[haider]

hey guys,

 

anyone tried the exhaust header wrap?. was thinking of doing it for the aesthetic value la. But not really sure if its good for the engine.

I have been doing some research, apparently it keeps the exhaust warm/hot therefore increasing velocity of airflow.

 

A drawback was that it ****s up the headers with rust problem after a prolonged period of wrapping.

 

Does anyone have any suggestions ?
