any ppl here experience their super4 or any 4 stroke bike cannot idle in the morning? (usually dun need to on choke or set the air knob )

Just did tuning + wash carb evenually can idle nicely when engine hot...

but when cold engine the will die off after 30 sec?

 

Any body here care to share their experience?

i think i noe the prob.. its the battery... mine oso got this problem.. but nv ask the mechanic anithing abt it when i go carb servicing... then when he start the bike onli.. he already noe got prob liao... and told me that my battery cfm chiong one... then he open up and check.. indeed is a GPR chiong battery.. and advise me to change to YUASA... so why dun u go and check on ur battery too.. if urs oso chiong one.. then at least we can confirm the source for this problem liao... hope u check liao can post here or PM me.. BTW... if i not wrong.. yuasa oso have chiong one.. so i think its best u ask a experience mechanic

i still can't seem to c the triangle plastic thing leh..

is it rite in the centre of the carbs.......

or nearer to the left side or right side......

 

if u fix engine guard, it is harder to reach rite....

easy to reach after u remove the tank

insert ur hand from the left hand side while sitting on ur bike.

U should be able to reach it.

But careful not to scald ur fingers !

 

Enjoy fingering and turning the knobs,,,,,,,

reach into it from the left... its better if u adjust when engine is cold... or put on a glove or something if ur engine is warmed up.

cold engine to advisable to adjust lah.

later when hot liao u realise it's revving too high u must tune it down again.

 

Acutally some motorthiams got special long nose tool for adjusting the knobs.....

Check the out !

[darrenx]

hmm...But what has the battery got to do with the idling? Can recommend me your mechanic to me?

I suppose when the bike is crank n started, the battery is not fully charge up & the voltage is no stable?

 

So what is the effect after u change the battery?...can idle nicely every morning ( cold engine ) Got include change rectifier?

 

COnfirm mine is a Lim ah Boy YUASA battery. and the rectifier also

 

Any 1 here have been using ah boy battery and have the same problem?

[darrenx]

but the hor....what i ask ard is that after i start my bike liao, even i take out the battery my bike also will idle lay...the battery is just the electricity to crank the starter motor to start my bike onli.....

[bktan]

was adjusted by ah tee at combine he adjusted it to 400 rpm is that correct? it seems a bit tad low. But the bike runs fine and starts up normal even when cold.

 

what do you guys usually set at?

 

and the idling screw is a roundish black right in the centre of the four carbs right? its portruding straight down vertically am i right?

[SiaoSter]

its suppose to be slightly above the mark ' 1 ' on ur meter

[Guest VinGrace]

I thought it was suppose to be 800rpm.

[bktan]

so am i right about the location of the idling screw?

[Guest engsoon8]

yup... ideal is 1200rpm... just nice and sweet... i heard new bike's factory setting is set at 1500rpm... haven't seen it for myself tho...

[fierydoink]

My specII idling is around 1.1k, looks abit high. What should be the best idling rpm?

[HONG]

around there lor.. if u find it too high u can adjust to 800rpm

[PaLmEr]

800- 1000 RPM would be good

[weixiang]

hi guys..anyone can roughly help me along to describe the tuning of the engine idling..? mine i suspect is to0 low, resulting in stall engine when i leave alone or even when downing gears to slow down or come to a stop..

 

thanks very much..

[Guest quizesilver]

manual say 1350 +/- 100

u can adjust the idling below the cab
