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

[Q] Anyone knows how to install the ACERBIS (MX Uniko Handguard) onto Spec 3 before? I went to ah boy shop and buy as they told me that it can be installed easily.. When i tried to installed onto my bike, i realised that there is no space to install it..

 

After researching the whole afternoon today, i then realised that i get smoke when i buy at ah boy shop yesterday.. Would have to buy fat bar in order to install handguard.. Any recommendation of the brand and shop to buy fat bar? Is riding still the same after changing to fat bar? Required advice

[Q] Hi, my spec1 when travel for a distance, the temp light will turn on sometimes, then when light up during stationary, the rpm will suddenly go up from 1.5k to 2k. then when hit 2k rpm, moving off is not smooth. sometimes temp light no light up also will have this problem anyone encountered this problem?

Have you check your coolant? Maybe no more reserve at all or not enough coolant. Can check on the left side of your bike.

[Q] any fat bar brand to recommend? Went ah boy shop to buy ACERBIS handguard and was told that can easily mounted but without the knowledge that fatbar is required too..

 

Anyone can advice if riding is still as smooth and normal after changing to fat bar?

Hey guys,

 

Whenever I ride over bumps on the road, they hit my bike hard and I can pretty much 'feel' every one of them. It is like my suspension is not even there. Should I be servicing both my front fork and rear suspension already? Or does my bike just need some adjustments?

yup, u might need to service both of ur sus with a higher viscocity of fork oil.. can look for david ong! at bradell..

but fyi, s4 exhuast system is really low de, hence sometimes must go really slow or crawl over the hump.

lol

o yea... i learnt that the hard way...

[jayz]

oh man. i got the same problem as bro @thechosenx! on the bike, no low beam but high beam ok.. wth man. then i open up my headlight, adjust it myself, got low beam liao, NICE!! then put back the headlight, low beam gone again.zzzzzzzzzzzz, after that i give up, put back headlight, 1 screw cannot put back, in the end put 2 screw only, tml morning go bike shop do liao. sian! will update here what's the problem.. wish me luck guys.

[thechosenx]

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..

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?

[confusehaha]

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.

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.

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.
