Did he took off his tank ltely b4 this happened?

Thks Ah Pek,

Is a used bike, after riding a while, it was discovered a slight eo leak ard the engine block area that has already been fixed by the seller. Surely, it must have removed by the seller to fix the engine block area.

Is there anything that related to removing of fuel tank and any advice to help on this. thks

The reason I asked that is because from th sympton you describe..definitely the engine combustion chamber is deprived off fuel or electrical supply to the ignition coil.

 

1) There is a smaller tube (out of two) that fit to the fuel tank under it. Most people take it off but some put it back. This tube when not properly sit thru and bend, the tank breathing thru the tank cap is being blocked..this is just a possibility. One easy way to find out is when it happens..open the fuel cap and har if it has a sudden "hissing" sound..if there is, that tube is blocking breather air for the fuel tank.

 

2) Another possiblity is that the vacuum tube may be improper as such that its punctured due to using plier gripping it while pulling it out. Its a small tube that couples from the fuel kock to the mid engine block on the left hand side of the engine. if this tube has holes..vacuum function is affected such that it does not work efficiently enough with the diaphgram o provide enough petrol to the carbs..thus more fuel is use from the carbs than it can provide from the tank.

 

3) The 3rd possibility is electrical and its regards to wiring which is hard to identify..from loose connection to lack of voltage supply (internal wire corrosion) to ignition coil and I won't rule out a weak magneto coil too as its the source of electrical supply as in "energy" after a bike starts.

 

There may be other possibility but at the moment there is nothing else I can think off. Btw, I forgot to asked is this very regular or was it a one time off thingy?

yoz need some help here...

 

mine bike toda suddenly cant crank at all...the starter seem to be shorted...

let me explain more

a)when i on ign,the odo does not light up

b)when i crank start, the odo meter like shorted(even the clock also gone)

c)when i like tilt the handlebar left right(sometime it will be normal as in when the starter wiring at the throttle side being adjust)but still cant crank,once press the starter button the clock and the odn meter will back out again

d)the thing go normal i push start, den when i press the starter,it dies off again(like everting is shorted)

 

can any1 advise?tks in advance

hmm, maybe u check the fuse? open up the left side cover and theres a black fuse box , open it up and u will see alot of fuse.check whether are the fuse already burnt or not.

[eement]

ya i check already fuse is ok...i even open the whole meter assemby...but i check seem to be like the starter problem leh

Get a new battery..when all else start..check your charging voltage..should be 13.5v dc to 14.5v dc. If anything below 13.4vdc, magneto or rectifier or both got ptoblem liao.

 

If your battery was change two weeks ago..confirm your magneto or rectifier or both gone liao becasue battery is not being charged.

 

Take out the battery if its still quite new and go to bike shop to charge..ride to mototiam and check charging out put b4 you can't even push start..meaning magneto coil total burn out.

 

If all the above don't applied..wiring problem.

[eement]

haha but muz be lucky b4 i got the position of the starter wiring...not very easy...battery juz change recently...tks anyway

[eement]

juz call the bike shop...and was told that it was the starter relay problem....

[zakibabat]

Hi,how would we know if our front brake disk need to b changed?

[derosis]

hi guys,

i am having a problem, now when i turn my key on, the voltage shown on my volt meter is only 11-12v, previously i think it was 12-13v++, i just changed a new battery but still having this problem. could it be rectifier or coil problem?

[shunoski]

If it remains 11-12v when the engine's running, then you really have to worry.

when my engine is running, when i never throttle , it will remain at 11-12v stil... but when i throttle , it will go up go 13-14

if will go up to 14 should be ok .

[derosis]

if will go up to 14 should be ok .

 

okok...so i do not need to change anything?

[koxie]

if u rev your voltage increase it shld not be a prob.if at idling and u on your signal light,the voltage drop to 6~9v then u got to change a new battery soon.That what happen to me.

Okay, Thanks

[idun69]

it happen to me too but after i start my bike it go up to 13 v++ so it shud b ok..

a few things will contribute to the initial reading of your batt.

 

1) what are the lights that are ON when u turn the key? (w/o starting the engine)

2) where did the wiring of the voltmeter leads to? (batt? lightings?)

3) what bike u riding?

1)only front 2 signal light(pilot light)

2)tap to lighting i think

3)cb400 spec 3

[LollyPoP]

4) what's the voltage reading during idling?

5) in neutral, try rev to 4-5k rpm & take the volt reading again.

when just engine cold start, will be about 12v+ , when i on my hid, will be 11v+

when 4-5k rpm rev, voltage will be around 13v++

 

means my bike is okay?previously when i have not change my battery, when i on my HID, the voltage went to 10v+

[Gorudonasaki]

Mine also, when turned on ignition, voltmeter reads 11+v. After crank is around 12.5v. But when idling at traffic lights, it'll fluctuate around 11.7-11.9v. I guess i should change a new batt soon.

Hello everyone, I need some advise on what to do with my S4 Spec 1. It seems that it is sucking the petrol greedily! I just bought the bike recently, less than 2 months old. I've read this forum on fuel consumption and it seems that for Vtec 1, u can get an average of 300 to 360 km before it hit reserve. Mine hit 230 before it hit reserve! Anyone knows why? I've changed the air filter to stock,synchronize the carbs and just changed the floater pins.The diaphram still looks ok,no breakage or cracks. I'm at my wits end to find out why there is so much diff in comparison with the rest of Spec 1s.Can anyone help? Ah Pek? Pleasssseeeee....

[ezafiq]

@azizhussain

wah bro 230 very jialat leh. mine can do 300 only before reserve which i fine it sucks compare to those who can do 360 before reserve.

If you read those super high ones are normally those without vtech and travels mostly on highway and no jams. Last time mine also 230~250km. Check if your brakes pads rubbing very closely on your brakes. alot of black hearted bikes shops just remove old ones, use brute force push your brake pistol inside and fix new ones without checking. imagine yourself riding with brakes slowing you down when you nvr even apply force to your braking system..
