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

Nothing to do wif ur petrol but I suggest u use Ron 95 (I skip the detail for now).

 

There are two possibilities that caused ur engine to be that hot..1) bad cooling system and this means can be from insufficient coolant, jammed thermostat, coolant pump not working etc. 2) Eo not good enough for ur kind of riding style and usage or eo level below specification (plse note that there is a eo brand that can drop in level when use).

 

Ahpek..currently i am using maxima eo..coolant i oso use maxima..will go down bike shop to check..will update u guys back..thanks again ahpek..

Hi bros,

I'm currently on a spec 3. I just wanna ask: Whenever I'm in gear 1/2 (at slow speed) , the front wheel makes a tic tic tic sound. It sounds like it's coming from the front brakes. Any idea what is the problem?

Planet Moto, MotoWorld, Raceweks or Unique and some of the other advertiser here are familiar with S4. They can all handle changing of the thermostat and yes..if it's jammed.it cost overheating and intense evaporation of coolant and boiling.

Ahpek..the saga continues..apparantly its not the thermostat,coolant or etc..its was actually the radiator fan switch tat was faulty..however the shop quoted me 80 to change it..the switch wire was faulty or sumting which resulted in my fan not switching on properly even when its hot..it will switch and suddenly off..however i was so shocked at the price quoted and not to mention they gotta order it and told me come tomorrow to fix..i feel like tis one silver chop..so maybe i will avoid the place..aniway is it possible to make the switch have a relay or sumting,meaning i am able to turn on the fan on or off freely without waiting for the heat to automatic turn on the fan?where cn i do it and the rough price for it..thanks ahpek...

Cover it? Pass your key to someone to warm up?

Disconnect your battery n keep at home

 

Do charge the battery before u start the bike after you back from trip

[HaiR1]

Tis is to ensure that the battery doesn't discharge by itself during the 6days of not starting bike

 

 

Else, ask some1 to warm up the bike daily

FY?

 

 

Batt, rectifier n coil + labour (standby ard 600-700)

[haziqsuperman]

Plate fy, 600? Wow, that is alot. If my coil and rect is still good? Isit safe to just change the batt?

Depends..

 

How u knw it's still good?

 

Better to change as a set if you can afford. So If anyting is faulty, u can take note the lifespan of the batt/rectifier/coil

This 3 is the main cause of failure on the bike, ther than your cdi n ect

[HaiR1]

Do check for any current leakage from your wire/wiring harness, loose wiring n ect

 

 

Bring to a reputable mechanic when in doubt

If change coil n rectifier , not more than 400. I changed both last year at racewerk..norman told me now adays many chiong recitifier in the market...If plus batt depends on wat batt you use..

Will it be enough?

Need some help from the pros. Currently CB400SF2 using stock filter/exhaust. If change to hi flow filter and full system exhaust, do I need to do jet kit for carb?

[gamerzdude]

you won't "die" if you don't do a rejet. You can still continue to ride happily forever

 

but if you want PERFORMANCE, then yes you definitely need to do a rejet. Your air/fuel mixture is no longer optimum since you changed your air intake and output.
