Warming up of Engine

[nathan_12]

well weneva i go 4 a run, i will warm up! or else will get muscle cramps! same 4 bike i gus! if dun warm up, wear n tear will be caused faster!!

[Darkness19]

during morning i will usually warm up my engine for abt 3 to 5 mins be4 riding,but for the rest of the day i will just move off aft starting my bike

[ops-fd]

u got a habit of whacking ur throttle and straight away off ur bike?

 

yea you are right about his riding style

[Darkness19]

is there a need to rev the throttle and then straight away off ur bike?

[FrdAuZ]

I think wat he meant was to warm up ur bike first before movong off, dont just on start and whack ur bike off.

[warrior.c.o.n.p]

1 min will do to warm up my bike. unless u wanna take a puff den its up to u.

[ridhzam]

i usually warm-up my cbr400 abt 1-2 mins.move off with low rpm till when i feel engine runs smooth den start to rev higher.

 

i ever heard ppl say if warm-up too long,yr rectifier will easily get burn.dunno how true it is. any idea?

[Ah Pek]

Odes bike need to warm up?..answer to me is not a neccessity thing required to do. You don't go by how warm the engine should get..or timing it from cold start and the runtime should be. What exactly here and most important thing is that there must be enough time given for your motor oil to complete its lubrication path and normally time required is about 30 to 45 seconds. This way, your bike stays in good condition.

 

If warming up refers to having your idling stable at the setting you want...that's another thing. This varies from freezing cold rainy morning to a hot baking afternoon sun..and also your fuel and air mixtures. What I'm trying to say here is warming up the bike need not to have your rpm needle staying stable at your preference setting...what important is that, at least your cyclinder block etc..has to be "lubricated". Once that's done..one can ride off and the rest of thing would take care of itself...like stable idling (as it varies with time of the day after starting off).

You should asked them how many rectifier did they done so with that. My question is..base on what logic? If one is stuck in a heavy traffic jam..the rectifier is at stake?...cannot be lah..aiyo_yoh!

[JbAtRaCeR]

What i always do in the morning is let the engine idle for a minute or two,once the cylinder block is warm then i move off. S4 engine is made of aluminum alloy,as we know aluminum heats up fast and loses heat fast too unlike cast iron. So warming up is important,you whack too fast(start and open vtec) and few years down the road,you will end up with warped engine components like cylinder head,cylinder head cover and etc.

hahahaa...

then you'll die first before the bike die...

 

hehehe.. joking..

 

i also do the same

[ghost04]

once ur idling is stable can move off already...or start n ride off slowly..

[kurarensu]

for me start already see the idiling is my usual idling i move off.. cos morning start always fall below the 1k rpm.. then let it warm until the exhaust air feels hot.. engine feels warm not too hot ready to go already.. then test by blipping the throttle abit n see the rpm comes down still below 1k or above.. if above i'm ready to go aha...

You want to know the correct way about how warm up is done?

 

http://www.dansmc.com/indexindex.htm

 

It is just like our human body.

Before any run do you warm up?

The same thing with a bike which is meant to run in the wisp of the throttle.

your best bet,plan your time early for at least a warm up of a few minutes.

And do fiddle with your clutch to introduce fluvial motion in your sump and clutch housing.You will notice the gear changing sequence once you leave your car park.You will thank me for it.

 

This is how I have taken care of my 14 year old bike.

 

Thanks and cheers.

fiddle wif d clutch after a few minutes of warm up or straight away after starting engine? fiddle like how?

[Mageswaran_g]

The fiddling starts once you have sat on the bike

after starting the engine.

 

Just clutch in and out without engaging

gear.The clutch springs will cause the clutch plates in the housing to move

causing the motion of oil.

 

By doing this pump action,you are helping the sumped oil to be introduced

to the transmission.You should do this in the beginning and for about a half minute prior to taking off, towards the ending of warm up.Don't rush.

You will strain your fingers.Maybe 1 second one clutch pull or something.Up to you to work out.

 

Ultimately no right or wrong way in the frequency of clutch fiddling.(As many times as you want).

 

The long term benefits are that you can see a longer interval in changing the worn out engine components.

ppl out there i got a question how come every morning i start my bike it will die off i need to throttle my bike for 3-5 min before it can be stablizse i wonder what is the cause of it btw it a ver S hope some one can help me out

Maybe you can check how long since you last change engine oil, what is the rpm when you first start your bike in the morning, is it too low?

 

This is usually the 2 things which affect my bike in the morning. If they are in good order, i have no problem starting the bike in one crank. It will somehow have a very low rpm at the initial stage, like want to die off like that, but at least it does not stall and will stabilize as the engine warms up.

 

One thing which i never do is rev the engine and switch off immediately when i park my bike the night before. Unburnt petrol might remove whatever lubrication is there in the combustion chamber, this will cause more wear and tear in the long run and might also affect the startup the next morning.

well i jsut took over the bike not long ago so i change the engine oil and oil filter i not sure is it my problem or is the bike tat giving the problem eveyr morning i start my bike it around 1000rpm and i cant just leave it to warm up it will jsut die off unless i throttle around 2-3k for around 2-3 min than it will stablize so i was wondering wad the problem

Have the condition of your carburetor check as well. When I start my bike in a cold morning, the rpm hovers just below 1k rpm, it will slowly increase as it warms up.

 

When I just took over the bike I sent it for oil change, coolant change, carb service, change brake pad, change tyre.

[siansation]

hmmm but it wun warm up itself unless i hold the throttle for a few min i haven check the carb... i will go check it sooon see what the shop say

[longjump]

hmmm my spec2 is the other way. easy to start when cold engine but after i ride the bike for 5 to 10mins n if there's a need to switch off engine, want to switch on again need a number of tries. if u anyone can advise.... also is it advisable to open throttle a bit when switch on the bike?

Dunno why like that..

 

For me, it is ok to open abit of throttle to get the bike started if the bike has already warmed up, because the engine oil has been circulated into most of the engine parts.

 

It is not so good when the bike is cold after a night's rest, most of the engine oil has been collected at the sump below the engine.

 

But if really need to do that, can first get some engine oil onto some parts first using methods that others have recommended here.

 

A certain amount of pressure is needed to push the engine oil around the engine, this is not possible if the engine is not running. So the most we can do is try to minimize damage during the initial startup after a long rest. This is the time where most wear and tear happens.

Logical also... but some say dont let ur bike get used to that kind of starting of engine... but i agree initial startup is important like breakfast for the bike

Have you tried using the Choke?
