But it's a bit pricy lah. US$34 per set.

[Palary]

Under the Manual, for every 20,000km; there is suppose to be a valve clearance check, has anyone done that?

 

Notice that this website keep having error and slow with "too many conenctions" report...is it just me, or someone you also experiencing this??

Hello Casper4xxx...!

About the free entry...no ticket needed,Friday only....... was introduced last year by the organizer.This is because they want more spectators to attend this event.Since 1999 when the curciut was just opened it was @$48/- for 3 days.So last year the owner that is Patronas want people all walk of life to come and watch the race.They are selling as low as @ $3.70 for the hill stand and @ $6/- for covered hill stand.But the news came too late and not many ppl (locals) came.These prices are for race day only...but still worth it...!So Casper at S$25/- (Sat/Sun) I think you have no problem.Silvergost thanks for the reply...!Casper, you have less than 2 weeks to decide.To up-date you, 3rd Oct the race is in Qatar then followed by Malaysia that is on 10th Oct.......

Hey Palary,

After you mention I notice that most of us guys have rode passed12,500miles X 1.6 = 20,000km need to send-in for- Checking Valves Clearance/Adjustment.

 

Do not forget about the Fuel Filter it is time to check it condition too...

 

Check your manual on- Periodic Maintenance And Minor Repair, page 6-2.

....u see, Shaji encountered Engine oil 'missing ; but there was no leak; The shop check and found some white smoke from the exhaust. It could be engine oil goining into piston...

 

The shop suspect it is becos of the valve, which should be checked periodically as stated in the manual. But which he doesn't...

Thus he has to do a top overhaul now...abt $1K....

 

So I'm abit concern now..

Palary,

This is not only your concern it is every riders...!

 

If I 'm not wrong; I think shaji's mileage is way, way ahead.... . I have check with the workshop as they say it is okay 20,000+km no problem, just bring the bike in about to reach 40,000km.

You may able to know can feel it went the valve need adjustment.... when the bike is loosing power, tappet sound is louder then usual during ideling, timing slightly off, once in awhile back fire, need to accelerate more then before, engine oil burning smell this is all the sign...white smoke is too late already. !

 

That's why!!! always warm up your bike give and take atleast 5 minutes do not accelerate hard while the engine is warming up... how do you know the engine has warm up already..?

You able to notice/hear there is a sudden drop of engine roughness/noise..and the engine will be running smoothly... ..

Brudder Silverghost I did experience all of those systoms which u mentioned at one pt or another, does tt mean i need to send my bike for checking valve clearance.I do proper warming up every morning..mileage now is about 24000km.Once in a while, there'll be back-fire when i start the engine..tappet sound sometimes loud sometimes ok.

 

Which workshop did u check with?Did u ask them bout the price for such checks?

[haroze]

Hi bro...

I agree with Silverghost and Ccasper...! Warm-up your engine first about 5 min or so.Many at time I see riders start their engine and move off....very bad:giddy: About that backfire I thick it is time to service the carb and retunning.I

might service my carb at Tampoi near JB. Cost around RM80-110....

Hiya,

 

It only cost between $30 to $50 to service and balance the carbs locally. I did mine recently when I had the K&N filters installed.

Palary,

 

Carb balancing means the carbs are balanced with the aid of a vacuum gauge to ensure that all 4 carbs are performing equally. It involves also, the adjustment of air and fuel ratio for maximum efficiency without compromising so much on performance. Some places would also include adjustments to make sure the exhaust gas emmision is within legal limits for the CO content.

 

Valve clearance is making adjustments on the clearance between your valves and tappets and also the rocker arms. It is a "not too major" job but, the cost is considerably higher because of the amount of work that needs to be done. It should be a whole day affair at the workshop. It involves the removing of the top cylinder head cover to gain access to the cams and rocker arm mechanism. The clearance would then be adjusted, with the aid of feeler gauges, according to the values stipulated by the manuals. All gaskets around the top head cover would then have to be replaced with new ones.

 

I hope that helps clear the air for you.

OMD

Palary,

Valve and Carb are totaly different (parts) component... "Carbs" stand for as carburettor, OMD put it in short-form. Basicaly you should know it's functions.

Whereas Valves are in the engine itself on the top part were it's functions is to control petrol mixers in and exhaust out according to the engine timing.

As OMD already give you a brief details of the components and functions... !

 

Guys,

I just change my tyres front Battalax 020 $150/ at the back I cannot find the battalax 020 so I fixed Battalax 045 $130/..

 

Silverghost. .

[jleo]

On this topic of valve clearance adjustments, i remember asking HongLeong n the charges were upwards of $120 just for labour alone excluding any shims if necessary(all exc GST). Also u would have to leave the bike there overnight for it to cool down b4 they'd operate on it.

 

Irony is that shims like all metallic parts expand when hot n thus is better if adjusted when the engine is not fully cooled but instead hot. However unless u are willing to do it yourself, no where else is willing to do that for u.

 

My mileage currently stands at 21500miles n yes i've not even sent it for any servicing other than the scheduled oil changes. I intend to send it for a valve clearance servicing once it hits 25kmiles.

 

Btw OMD, where did u the carb balance for that price. Like to do for mine as well.

 

Cheers!

Hi bro.....

Just came back fr motoworld to change my front tyre a used one but still a very good condition.Cost me @$60/-.It is a mechelin pilot radial.a semi-soft compound. A lot of them mostly young riders were there to service their bikes.All tickets for the motogp were sold out....! I got my tyre from a guy who runs a few kilometer on the pasir gudang track.You'll be surprised....!If you want any advice at motoworld please feel free to look for Mr Fauzi.

Hi,

b4 going for cab balance & valve check, check ur air filter 1st. backfire can be anything from faulty spark plug; problematic CDI; cog air filter; timing out; etc.

Smell smell ur exhust for any pertol or engine oil.

cab balance is for opt. fuel consumption w all cylinder have equal air fuel mixture.

cab dirty also can coz backfire.

valve clear. is for loss of power w engine oil "eat up" by e engine.

 

I maybe wrong.... juz check 1st b4 wasting our hard earn $$.

:goodluck:

Custom,

 

By default, factory settings for new bikes are always on the lean side, meaning less fuel is mixed with air. Yes, it will give you more mileage but you won't be getting the "grunt" as and when you want it. Also, the vacuum between the 4 carbs are way off. So, the balancing of the carbs are somewhat crucial to obtain an efficient and equal power distribution across the 4 cylinders.

 

As for back firing, it could be a list of things that can cause it. It includes but not limited to :-

 

1) Leaking air intake manifold

2) Too lean mixture

3) Leaking exhaust system

 

As for the valve clearance adjustment, I believe it would not solve the problem of the engine oil being "eaten". Engine oil depletes even in normal engines. It is only excessive engine oil loss that one needs to be worried about. That is a classic symptom for worn out piston rings, which would also mean that the loss of power is noticeable (coz loss of compression in the combustion chamber).

Also can u tentatively tell me ard when so i can plan ahead if so.

Hey, we're mostly confirmed leaving on the 17th Dec Night. See if u can make it.

[SiLvErGhOsT]

Hi Guys,

Topic on back fire it is usually cause by a hot spot a particle inside the combustion chamber (cylinder) base on my knowledge,experience. (your air filter plays a part)

This hot spot has happen to some old generation cars when you off the ignition the engine still be running for a couple of seconds "want to die off, don't want to die off" these I have experience while I was a technician before.

How a hot spot occurred or happens to be there, this cause by deposits e.g carbon deposits, a dirt/particle slip in through the air filter, unburnt petrol or low octane petrol which dosen't burnt off completely, it is always neccessary to put in a high octane level petrol perhaps 95 this completely burn off if compare to 92 or lower octane level.

It is always good to top up with higher octane petrol 98 at a times for instant travelling in Malaysia this will clear out any unwanted deposit collected while in singapore traffic situations or conditions.

As what my friend(hackson) always say clear carbon..he,he,he,he...! Not him he whole life clear carbon..!

It may cause by timing but that can be quite obvious as the back firing will be regular and effects starting of you bike too.

Hi custom,

I break up for all the probable cause and problems to my knowledge....!

1) Air filter - cog air filter will cause choking (like you "pull" a choke) means high on the petrol and very low on air (mixer) another words, may cause engine to die off..! Always change to the OEM air filters why the gap/hole is much,much smaller then the K&N filters whereas the K&N gap/hole is much bigger so chances of big particles to enter the combustion chamber is high.!

2) Faulty spark plug - it depends and base on the engine timing control by the ECU eletronic control unit ours using T.C.I transistor control ignition (digital) system. Spark plug can be use for years on my former ST11, I take out the plugs check for any pitting or worn if nothing I wire-brush, clean with petrol and reuse it..for 2years+ No problem!, buy OEM plugs or better quality they last very,very long.!

3) Prolbemetic CDI - once you have this problem you can never start your bike at all..!

4) Timing out - cause by wear and tear of the valve. As for our bike it uses timing chain, gear-train(gear system) or valve-train system this part I am not very sure !

 

5) Smell exhaust - smell of oil too late already..!(shaji case) this means your piston rings have worn out this causes engine oil to sip-in. How the engine oil lubricates here...as the piston goes to TDC top dead centre (to the top)' the engine oil is splash on the cylinder wall under the piston, when the piston returns it slides down as lubricates/scrape down the oil along the cylinder and making it air tight, sealed.!

This is the reason why 4s bike engine oil is dirty(black) compare to 2s bike remains almost the same colour as you top up(orange)...

Piston rings and the engine oil makes it air tight so the explosion inside the combustion chamber dosen't leak/escape or lost...if the piston rings has worn out the oil will be left out along the cylinder exposing to the combustion(burn) and the same time lost of compression. These is where the white smoke comes and the engine oil is burn out causing high on oil consumption...

6) Carburettor 'cabs' dirty - can cause lost off power while riding you can feel the bike like "want to go, don't want to go" like you can never achieve that regular speed smoothly or properly....(back fire? no-way..!)

 

All this base on what I have studied before! This I hope may help you people to understand more about the bike.!

Mind if I ask a potentially dumb question...

 

 

Can a standard Divvy get one of those TP head-fairings??

 

They look nice.

 

If can, where can they be gotten locally?
