How many of you stop yr engine whenever u come across a red light ?

[CCharles]

It is not good to switch engine on and off too frequently

[silverstein1982A]

Used to off it during the 2B days at the TPE punggol exit towards sengkang when the traffic light just turn red... take quite a while

[fmaorui]

I guess if you already know the red light is gonna last quite awhile then just off the engine. If its your generic traffic light then there's really no point you save like 5seconds of petrol.

[Stephen Bond]

I have done this a few times when critically low on petrol (as in, running on the last few drops) but no other good reason for this practise.

 

I now ride a machine that dislikes idling a lot due to heat buildup; my solution is just to avoid jams altogether.

 

Yes I completely agree with you on this.

[Ah_Pet]

i nv off my engine but only at custom only..

the most i just out side stand while waiting for traffic light.

Toasty engine?

 

Someone might have tuned the bike to run a bit lean, for better economy and power.

 

Turn up the richness of the air/fuel mix and the engine will run a bit cooler. Right, that's one benefit of a carb over FI!

 

If you see someone poking around with a screwdriver at the stoplight, that's me

for water cooled engines there is no need to turn off the engine due to heat. the radiator fan should keep your bike cool enough. If your fan does stop the temp from rising then you may have a faulty cooling system.

 

Other than this switching off is a choice, not a necessity.

[kokkikok]

Why don't car over heat easily...

[ben1112]

big radiator, big fan.

[squarebox]

I off my engine at very long traffic lights and it just turn red.

[DeusExMachina]

When you turn off your engine, your coolant pump also stops working, and coolant stops circulating. Your engine temp will actually rise up.

 

Now, if you're parking for the night, then that's no problem. Temp rises for a couple of minutes, then will start to drop.

 

You stop at the traffic lights for 1 minute and you stop your engine? All you'll get is a higher temp when you restart your bike. Try it out. Cut your engine, leave the ignition on, and see which way your temp gauge goes.

 

 

Also.... if you keep cutting and restarting your engine, you're gonna drain your battery very fast.

 

Take a voltmeter and measure the voltage drop everytime you hit the starter.

 

So... Go ahead.... cut and restart your engine at every junction. Let me know if you have to push start the bike after the 15th restart.

[xXxRatedxXx]

This thread make me lol.... if uncomfortable about the heat at traffic junction... ride 2b bike.... its just nice! Warm and toasty instead of ball frying action on some bigger capacity bikes!

depend on certain bike model. i rem my TL1000R can heat till 120degree b4 fan came on and oh my the air blowing toward me was damm hot! thay y i always armed with jeans and boot when ever i'm on a class 2 bike.

[ragavan]

Make it to neutral gear. it can save petrol instead on gear 1. On-Off-On not good for battery. Also if u not aware enough to on ur engine on time, then people behind will start to horn u ready. lol

[Zer0]

you know when you turn off the engine you turn off the water pump and the bike will heat up MORE as the coolant stops moving?

 

Especially when in slow traffic much better to just install a fan switch and flick the fan on permanently to cool the bike down and leave it idling. Most fans are set to cut in around 105 and back out at about 98 hence big bikes stay at very hit temperature when waiting in traffic. Manual fan switch will mean when you KNOW you will be in heavy traffic you just turn it on full time and it will bring the temps down to 90+ range and hold there generally.

Yeah I agree with that, I always put to neutral rather than turning off the engine which I find is more troublesome even though mine is e starter.

good lesson i learn today:thumb: time to fix a fan switch.

[steel_headz]

I don see any reason to switch off n on again n again....

 

To me it will only be relevant if im at the customs when the need to queue for ur turn...

Love your profile pic man!

 

And yeah, no use switching off, consumption is minimal.

[Cyanide14]

for me at long traffic lights, i only switch off my headlights.

[jack oh jack]

if fix fan switch, den will have e feeling of having a hair dryer between ur leg..

the hot air keep coming..haaa

[DM]

if you know the wait is gonna be long, eg. stopping at amber->red lights at cross junction where other junctions take turns and the engine is heating up quick, just switch it off as you please.

 

let's be realistic, how many of such particular situations do you come across everyday? even if i do come across it more than once, i'll most probably only switch it off once and let the fan run on other occasions.

 

 

true that once the engine is off, coolant pump stops turning BUT

 

 

engine also not running anymore = less heat produced.

 

 

and important note: even though coolant pump not pumping, coolant will still circulate due to thermosyphoning effect.

http://en.wikipedia.org/wiki/Thermosiphon

 

even if the pump is pumping coolant, it still requires the fan to cool the radiator.

 

then again, i don't recommend switching off the engine at junctions. you may never know when some clown comes speeding down your rear and doesn't stop in time or if the lights turn green and you fumble to start the bike, causing a bunch of impatient drivers honking and flipping the bird behind you..

i turn mine off too.

hot weather, can't let cooling fan turn on.
