How long should a bike be left at idle before it is fully considered to be warmed up?

[crazydj]

Hi guys.

 

As the title says it. I was wondering because i wait for my bike to warm up about 1 or 2 minutes and the idle speed is at about 1.2-1.3K. The engine sounds as if it is at that particular rpm.

 

But after riding for a longer time, about 15 mins, when i am about to park or turn off my engine, the idle RPM is at 1.8 to 2k. The engine sounds as if it is at that particular rpm.

 

Firstly, is this normal for my bike? Secondly, when i want to set my idle rpm, should i set it when engine is warmed up for 1-2 mins or when the engine is hot? I normally set it when the engine is hot.

 

Thanks!

i also like to add on to the question.

 

when i leave my bike to warm up after a minute or 2, everytime i engage 1st gear, there's a CLUNK sound and the bike like jerks abit. thats only when I shift to 1st gear, 1st time for the day after overnight parking.

 

immediately after that, when i shift to N and back to gear 1, no more jerk.

 

anyone mind explaining?

The clutch plates are sticking. Can be due to worn clutch components, cold oil, or just simply inherent behaviour of your bike.

set for hot la,

then If when cold too low, just use choke or play throttle.

[liquidy]

usually i would warm up till 60 degrees. which takes around 2-3 mins for the engine to be lubricated and warm after the cold night. and also to ensure that petrol has ran through the system..

wah so fast. Wat bike is it?

My bikes i smoke one cig also not yet 60.

1. Yes... i ride YBR before... you want to warm up... up to you... want to just ride off... also can.

 

2. Set when engine is hot... but you will have trouble starting in the morning if you do this cos the RPM is still low...

 

3. So what's the best way? Just leave it at "hot" idling... when you start just hold the throttle slightly open... Then you won't have to keep adjusting...

try with class 2 bike, confirm will hit over 60.

The most effective way to warm up a bike is to ride slowly initially. There is no need to leave it idling.

Wah ur warmed up idling speed so high? 1.8 ~ 2K is it manufacturer spec?

Yes, please warmed up the bike before adjusting idling speed.

For my bike I use the temperature gauge as a guide, as per owner's manual warm up the engine till it reach slightly beyond "C" will do. For my bike, I can see that during cold start the tachometer fluctuate, after its warmed up its much stable.

Its OK, that you ride your bike without warm up but don't rev the engine hard.

Actually its good that we warm up the engine before ride, it can break down the viscosity of the engine oil so the engine need not have to drive hard.

Some mention that our gears are constant mesh, if its warm up it can have a better clearance between them.

Our catalytic converter operate at high temperature, if we warm up the vehicle it can reduce harmful emission and help save the environment too.

Personally, I feel better response and smooth pick up if engine is warm up properly.

If your bike has a cat, more so you should ride off, slowly, immediately after your engine has started that is to get your cat temperature up quickly otherwise you risk the case of poisoning the cat.

 

[ChaoPuzzy1968]

warm up as soon as i finished my cigg

[crazydj]

The thing is that, if i wait for my "engine to warm up while idling for 5 mins" and set the rpm to the recommended 1.5k, the next morning, when start engine will die. When i start my bike, the rpm will only be 1 or 1.1k.

 

If my engine is HOT after a long ride, and i set the RPM to 2k, when i start my engine in the morning. my rpm will be about 1.3-1.4, then after 2 mins, it will reach 1.5k rpm.

 

I hope you guys get the picture.

 

What is wrong with my bike?

[yeukeong]

If u set rpm at 1.5k when engine are hot... the next morning bike will die due to low rpm...I dont c anything wrong in ur bike.......

 

Maybe u r not use in pulling the choke....

Okay. Let me explain.

 

Engine is HOT. Long ride. Set idle RPM to 2k. Next morning, cold, easy to start. Due to high rpm. When engine is warm, RPM is 1.5k.

 

Or

 

Engine is warm. 5-10 mins of riding. Set idle RPM to 1.5. Next morning, cold, super hard to start. When engine is fully warm, RPM is only 1.3k, super hard to start.

 

For both cases, if i set idle rpm to 1.5k, morning sure cannot start one.

 

Bike RPM will be different when WARM and HOT.

 

WARM--> 10 mins of slow riding or warm up for 5 mins. RPM will be at 1.5k.

HOT--> 15 mins or more of hard riding, RPM will SHOOT UP to 2k.

 

Basically, my RPM will be different values when engine is WARM and BURNING HOT. Normal?

[lacrimosae]

Always allow your engine to idle for a few minutes before moving off as this will ensure all parts are lubricated, lubricants are warmed and fluid, and piston(s) and bearings have reached optimal tolerances (which gives you a better seal at the piston rings, etc).

 

Moving off cold and 'warming up gradually while on the move' puts a strain on the engine when it is cold. Neither speed nor rpm is as critical as the engine load which stresses a cold engine.

 

You can also use the time for warming up to check your bike for any faults, like your lights, brakes, tires, and perhaps clean off the paw prints of a nocturnal tenant left on your seat or tank.

 

Your engine should be set when it is hot, after you return from a ride. It usually runs richer when hot, so when you set it hot, you will get the best performance throughout the entire ride. When you start cold, it will run slightly leaner, hence the rpm will be slightly higher. Just use a little bit of choke, for about 2-5 seconds in intervals during the warm-up phase until the revs stabilize.

I agreed that riding off slowly would speed up the temperature, sadly my car park to main road quite a short distance. Hardly the vehicle would hit optimal temperature wor.

hmmm the idling speed drifting, but is it within the tolerance?

No. 1.5 to 2k is a very big difference. If i set recommended idle temperature at 1.5k when engine is hot, tomorrow morning confirm super hard to start the damn bike. So i set it at 2k.

Am wondering if the tachometer showing you the correct reading.

Does the carb idling circuitry not compensating well or wrong compensation?

YBR comes with both electric and kick start right? Neither option works if its set at 1.5k, during cold start?

*need more evident to support the above theory.

[Pandoras Kitten 3]

Phantom have huge idle adjuster knob so I have different idling settings for warmup and hot engine and adjust on the fly. When tuning other Phantoms I don't care about the choke since I can temporarily enrich for starting conditions using the idler. (the choke is on the other side of the bike from idler)

 

I think it's normal on carburetted bikes for idle settings to drift since it can't actively compensate for atmosphering and operating conditions.

 

So it's either pull choke every morning and idle at 1.5k when hot, or easy start every morning but idle at 3k hot. Easier to tune when hot since we won't want to whip out screwdrivers at the next traffic light and drop the idling.

Hard to start, but if can start, the engine will die almost immediately or after 5-10 seconds.

[yeukeong]

Just wonder, ur bike is 4 stroke right??

 

When is ur last time(milage) to do valve clearance, top overhaul & service carb?

Never do all before. According my mech and my experienced friends, don't open the engine unless you really have to. If it still works, don't fix it.

 

But you think i should do?

[samuelftw5]

bro, its just carb problem. just pull choke, start it, and throttle it at 2k for 5-10secs. I dont think you need to tune the idling. Experience it before, went to ask quite a few mech.

[crazydj]

just pull choke, start it, and throttle it at 2k for 5-10secs.

 

Pull choke and opening throttle will result in the engine dying.
