HI,

 

I'm looking to buy the the S4 with 4 exhaust. Any seller with a reasonable selling price will consider.

 

Do pm me.

 

Thanks and ride safe all.

To be technically correct, I think you are looking for the CB400FOUR, not a SuperFour. There was one for sale in the classifieds a couple of weeks back...recommend you do a search under CB400Four, but I must warn you it's going to be tough to find a reasonably priced one.

Palmer, is there a twin pipe S4? I never seen one but would like to mode my S4 if the pipe are available as an option.

the twin exhaust i think is refering to CB 1300 the cls 2 s4.

[PaLmEr]

the CB1000 and older CB1300's have 2 pipes which i personally hate. Drop left side, change pipe, drop right side. STILL got to change pipe.

[rul]

i'm not biased against the rider... just that my friend and i nvr seen that bike before so when we did saw it, the name came up la cos of its 4 pipes and huge tyres

 

and i know there are other bikes like eg the mv augusta but so far in s'pore i've only seen the z1000

The CB400Four is quite similar to an old Super4. The way I see it, the 4 pipes is the major differentiation. Maybe someone can create an OEM 4-pipe version for Super4!

Hi, I been riding a S4 spec 3 since April 2006. The bike has been serving me well. But my previous owner has modi the stock exhuast and it somehow give a very rough sound.

 

Pls take note, the modification does not give me more power.....

 

I kind of saving money wanting to change the exhaust noticing that the exhaust pipe is rusting as well.....

 

I understand that instead of changing to original S4 Spec 3 full system, the Project Big One Full System will give S4 a smoother ride....especially on North South highway when touring....

 

Anyone knows if it is legal to fix a Project Big One Full System.....I kinda like the chrome finishing from Project Big One.....

[boon21]

Looks like quite difficult lei cos of e shape,sori if i'm wrong.

[adhlk]

According to mechanics, have to change some brackets. It actually is a direct fit as the frame does not differ too much....that's what the mechanics told me....

 

Anyway, Ah Boon, I hv introduce some friends to you for grounding. I believe they will call you tis few days....

[boon21]

bro adhlk,

Thks 4 free ad 4 mi as nw difficult to earn a living there loh(haha).Look @ my new products(S4 power cut) if u kicks in.If u chge to PB1 exhaust, make sure u take care of it becos i hve a few custs tat their end can rust n result in air leakage.Take care!

[VOODOO_DOLL]

Eh............

 

... i also not sure leh... i thought they r e same...

hmmm... mayb others can help to answer tis?

[Nokia6600]

Hi there,from my P.M told me is not possible to fit PB1 to Spec3.

 

unless u willing to do alot mod...

 

Correct me if i wrong..

[adhlk]

According to the Mechanic, there is special bracket to do that....but full system + installation will cost me abt $750....that will be abt the price of just fitting 1 Yoshi or Micron End Can....

 

Yoshi or Micron is good for bigger bikes, but no advisable for 400cc bike as the limitation is the horsepower....Correct me if I m wrong.

 

I m not so sure about the investment, that's why I m checking with experts here in the forum....

 

Another way to do it is to change the fuel and air intake. I am not willing to change as I do not want to adjust any engine parts.....Therefore, perking up the Exhaust is the only alternative....

 

Yes, I do crave for more power....but I prefer to have a smoother & safer ride at high speed (looking at 160km/h onli).

[bert]

If you are looking at only 160km/h... i reckon you dun have to change your exhaust... stock s4 can go 160km/h at ease...

 

if your s4 cannot go beyond 160... i think its time to tune your carb... change your spark plug.. etc...

 

are you the owner of FY silver spec3 at science park?

adjusting of air and fuel mixture is part of the carb tuning process.... and carb tuning can be considered part of regular maintainence...

 

unless you wanna ride an out-of-sync bike on the road that vibrates at high rpm with high FC and low performance.... tuning is a must...

 

btw... even if you change your exhaust to full system... you still need to re-tune your bike to a richer mixture to max the performance... therefore, higher FC you will expect...

[Nokia6600]

Not much differen.... :mad:

[adhlk]

The mechanic mentioned that increasing the air and fuel intake will increase the power. That requires you to change parts of the engine and retune the engine to meet the change.....

 

Actually, I realli don't know what he means......but when I heard changing of engine parts....den the 1st thing that came across my mind is to look for 2nd opinion.....

 

I have also read about valve clearance, tensioner +...many more adjustment....guess that I need to find out slowly liao.....
