Yup, me thinks the same too...

Btw, If I'm not wrong the only street legal version in sg is for spec 3 only

[ki113r]

Just a question to those S4 riders who changed aftermarket handlebars, is it for better handling, better cornering, lesser vibrations? Or just for the looks?

[kawa150]

hi guy wanna check ,do you guys know any shop that can reloan s4 spec 3 plan to buy from a fren which his bike is fully paid for? anyidea

[feelspeed]

can try bike production, republic motor or hkl . but ofcuz you gottta bring yr fren bike to the shop there as well for inspection.

[satan]

Hi bro. Sorry I could not help and solve the issue as i m a newbie to biking but I am also wondering what could be the cause of it. I hope other bro out there can share the solution?

IMHO, it only happened to me when engine is cold in the morning. Not hot. But ofcuz i don't high rev when engine is cold in the morning, definitely will stall and not good for engine.

Hi, ugu3tz.

Did your temp light switch on?

Did you check your coolant reservoir?

If your temperature sensor working?

Is your radiator fan in working condition?

 

Cause, if I may be allowed to make a humble guess, would reckon that your bike does not have sufficient cooling?

When your bike already hot, check if your radiator cool. If yes, your bike then cannot dissipate heat.

Happened to my frens Ver S. The cause is his radiator hose got leak - but then again, the bike, and hose more then 10 years already...

just my $0.02

I nver changed my header gasket before..

 

Get a constant 410-420km inclusive of reserve.

 

Been constant since I took over this bike, rode about 36000km so far under my ownership

 

Depends on how throttle conscious u r..

 

Bike is stock, running on

Yoshimura endcan

K&N airfilter

Denso iridium plug

AP EO

AP coolant

AP grounding

Venhill brakeline

Metzeler M5

 

Mileage currently 119k km

 

Noting much done internal as its still healthy, other than my coolant pump that just fail on me months ago. Not an issue, wear&tear

 

 

 

All this depends on the condition of your bike.

 

Just my contribution

[manbai]

[HaiR1]

Fc based on urban/spore riding style

 

If tour mode, 100% Vtec open, It may last me till Seremban.. If till KL depends on wat speed I cruise at

 

 

Vtec 100% open, ard >360km, depends on speed

Vtec 30-40% open, ard >400km, usually for Spore road
