Read story first poll - Stopping your bike..

[ZeroIndex]

Ok, had to think what to write for the title, but I'm fairly pissed off at one of these 'i am god'-syndromed wankers at work..

Ok, you go for a ride, lets say for exact example, from London St, Hamilton to Killarney Rd, Hamilton (hardly worth getting warm gear on for).. now, lets say for instance, it was on a CT110, and you were revving the heck out of it (which is the only way they get to 50km/h).. you arrive at the post depot, and you get off the bike.. and leave it running to "Cool Down"? WTF!! this is the first time i've ever heard of having to let a bike 'cool down'.. cars with turbo timers stay on for 1 minute to let the turbo "wind down and be happy" but a air-cooled bike? WTF

Seriously.. I've been on a few rides with people, and when they get from A to destination B, they simply turn off their bike and hop off.. This guy is full of sh1t isn't he?

I want this poll done, just so i can print it out and wave it in his face..

[crashe]

Ride my cruiser to destination - stop bike by either using the kill switch or the key and then get off it after putting the stand down.

Never heard of 'cooling a bike down' before..


EDIT
PS: I knew a guy that used one of these bikes (CT110) in Waitakere City to do the picking up the rubbish etc on.... He never ever used to cool down that bike.. start early in the morning - hoon around waitakere city picking up rubbish and putting said rubbish into those boxes on the back of the bike and stop at the end of the day - turn it off and put it on its stand - walk away. They got to take them home at night as well.

exactly.. this guy has 'had his license for 32 years', and he 'is right no matter what, cause i've only been riding for 3 months..'

and even if it was true, a ct110 is used as a farm bike, and what farmer in his right mind is gonna leave his bike to cool down, using 10 or 15 cents of fuel more than necessary..

[Pixie]

Yep,Brimming

[ZeroIndex]

Crashe: you forgot to vote...

[Biohazard]

Only let the bike cool down after a long hard blatt or track day, just to be on the safe side (old habit I have). NOT for 5 mins though.

Normal riding conditions no need to bother.

Turbo timers on cars - Hmmm kinda gay tbh, the only reason they do that is for the oil to clear and settle correctly in the turbo, roller bearings models do not need to bother.

[crashe]

Crashe: you forgot to vote...

damn it.. :whistle:


I was also editing in more info re the Ct110 bike...

[Deano]

Surely an air cooled bike can only get hotter once it stops and air is no longer flowing past the cylinder ?

[sunhuntin]

when im done, i just switch her off and go. she cools on the stand, without the engine...wouldnt that just keep her hot? and everyone i know that rides does the exact same thing as me....switch her off and go.

[crashe]

Yep overheat and die...
Then one has to wait around for it to totally cool down to restart it...

Seen it happen to a couple of sportbikes that dont have a radiator when they were travelling at very slow speeds (20kms and under) for quite a long distance.

[inlinefour]

The only reason that a turbo has a timer on it is to allow the oil pressure to drop. Warm down is a complete load of crap. I do not believe a bike will cool down quicker if left idling than the same bike switched off. Esp as the modern bikes keep the cooling system running until satisfied. As for an air cooled bike, the guy is a complete twat as it will cool down quicker turned off and we all know the said bike in this example is an air cooled bike. Next time I suggest that he bend over and fart on his bike as he is definitely full of something...

[pritch]

I've had my licence since 1961, I think... (It was a long time ago.)

Who said there's nothing new under the sun?
That's the first I ever heard of a cool down period for bikes.

In fact if I did that to my Honda, running the engine while parked would have the exact opposite effect. The temperature needle would climb rapidly.

I can't imagine that an air coolled bike is going to cool much after the air stops moving through the fins either.

Your friend isn't Irish is he?

my job is exactly the same, except it's delivering mail, not collecting rubish

[ZeroIndex]

That poll doesn't look very ummm scientific? :-)

it's not supposed to be scientific.. it's supposed to prove that even though I've only been riding for 3 months, and this guy has had his licence for 32 years, that I'm RIGHT!!!!!

[PaddyFZ1]

When i was reading about the Postie Challenge in Aus, they said they had to let the bikes cool down before they switched them off. There was so much heat created that they warp the heads. This is in temps around the high 20s, and being thrashed all day. Will see if i can find the thread with the link.

Edit:This was taken from the rider responsibilities section from the postie challenge web site
We have also found that bikes that have run at high speeds (70km/hr) that are then turned off for a break or refuelling can be so hot that the engine can warp while it is cooling. We therefore recommend that upon stopping, you let the engine idle for 3-5 minutes to let it cool slowly.

[dawnrazor]

cool down period, nonsense---now a warm up period is far more interesting, esp. for you 2 strokers out there.

Seriously though how long do you let your bike warm up for in the mornings, I wait for the temp guage to read 21 degrees, figurering that that is long enough for the oil to be nicely slathered over the shine bits and prevent any engine nasties. It used to take as long as it did to have a smoke, but now I've given up that vice, I look like a tit standing beside a running bike as I wait for it to get toasty, while I freeze my ass off.

What do other folks do?

[Ixion]

Never heard of a cool down period on a bike. And I've been riding for 40 years , which is more than his 32. And , as said, air cooled motor (no fan) is prolly going to heat up not cool down. Might make some sense on a bike with a radiator fan. But not much.

Having said that, after a long run I do usually leave the bike to idle for a minute or so, while I run a quick eye over it, just to check for any leaks that may have developed,new noises, bits fallen off, etc (Alright I admit it, I grew up with Meridan Triumphs - y'can tell can't y'). But that's a different matter.

No full throttling until at least 75 degrees.. and on the race bike, 80 degrees...

[Hitcher]

"Cool-down" period? How are you supposed to buy petrol?

[SimJen]

Don't bother yourself with old farts like this guy. Just tell him he's full of shit and that the whole world thinks otherwise.
He's the sort of guy that won't believe you, no matter how much evidence you produce.....some people are just stuck in a sort of twilight zone where all logic is backward.
Best thing for you to do is stick sugar in his petrol ;)

[Squeak the Rat]

Like running the bike in, I have put my trust in the notion that the bike manufacturer knows what is best for my bike, or at least that they won't keep something from me with the consequences of it harming sickle.

I believe the manual doesn't tell me to warm my bike down (though I will check). Do I believe Kawasaki or your mate? Hmmmmm

[ManDownUnder]

If an engine has been worked hard I believe it can help to cool it down, but for me that involves throttling off while still riding along - allow the air to cool the engine (via a radiator or directly on the fins if air cooled).,

To leave an air cooled bike stationary and running is only adding heat energy to the motor and no/minimal (if windy) air is passing over the fins to cool it.

Tell whoever to stop caning it a couple of blocks before the destination then turn it off when he gets there. Much more effective.

That all being said - 99/100 times (actually 999/1000) I don't bother cooling by bike down anyway. The latent heat in the block and surrounding hardware isn't enough to cause a concern.

If it was a jet engine - that's possibly a different story

[ManDownUnder]

"Cool-down" period? How are you supposed to buy petrol?

...by parting with $1.70 a litre... why - how do you do it?

[Colapop]

It's air cooled. It's designed to have air flowing over the fins around the engine (you can call them 'hot bits' while explaing this to the genius) how does the heat get dissapted if the bike is stationary?

I work with a few guys like that - they're called Smackheads, coz the only way they'll understand is, if you smack them in the head.

[frogfeaturesFZR]

:bye: The guys full of $hit, aircooled bikes don't cool down when running and stationary, I mean just ask him to think about what he said and if he's got 1/2 a brain he'll realize just how dumb he sounds

[SimJen]

Warming up is different, I always let mine warmup a bit each morning before I ride. A leftover from my Two Stroke NSR days, where you don't want to cold seize a cylinder.
If i've been going hard for the last few km's before home (as I usually do) then I usually let it idle just a little bit longer before I shut off, Not 5 minutes though....more like 30 seconds.

exactly.. but the tone of his voice when telling me 'otherwise', was if i took someones brand new Gixxer or R1, and was trying some offroad stuff on it.. it was like DON'T DO THAT.. YOU'RE GONNA *&%$ it UP

[dawnrazor]

I think he's refering to the fact that the engine is meant to turned off while filling the tank to avoid harmful fireballs caused by errant sparks :blip: :blip: :blip:

[The Tazman]

No bike will cool down while standing still. Why do you think people start their bikes and leave them to warm up!!!!!

All bikes air or water cooled need air flow to stay cool or at running temp.

I have also never seen it in a bike manual saying anything along those lines!!

I have had my lisence 20 years and have never heard such bollocks. Tell him he should go and surrender his lisence as he is too stupid to own it!!!

The guys a cock. Punch him in the face and tell him to stop bothering you when you're trying to work.

HAHAHAH Green rep for that.. i almost feel obliged to hand him a copy of everything written here, and then staple it to a phonebook, and 'phonebook him' <-- like in Dukes of Hazzard :yes:

[Macktheknife]

Nah mate you are right and he is a full'o'shit dickhead. Ignore him and carry on. If he gives you any shit just tell him to fuck off because he doesn't know his arse from his elbow.

[Madness]

A cool-down period on an air cooled motor is a crock of shite.

Maybe you could suggest the f*^+wit buys a compressor to blow air at the motor during this cool-down period. Dang, there's probably a few of you so you might need a big compressor, say a 33cu/ft model, 3-phase of course at around $5000. That should do nicely. Dickhead.

My sister is up that way - I can get her to come in a smack him for ya!!

Ask him if he pays for the bike or the running costs or the repairs or your wages... On second thought just ignore him - he's a twat.

[ZeroIndex]

he doesn't even ride one of the work bikes.. apparantly he used to, but he's so "I'm so cool, and I'm better than everyone else" that you can't tell if it's real or not.. kinda like "cry wolf"

[justsomeguy]

it's not supposed to be scientific.. it's supposed to prove that even though I've only been riding for 3 months, and this guy has had his licence for 32 years, that I'm RIGHT!!!!!

Mate,

If he does what he does to "cool" the bike down, ask him what he does to "warm" the bike up.

Then watch him go red as he realises you've just made him look like a fool.
:blip:

[Darryboy]

If I've been riding high in the rev range and hard on the brakes I'll pootle for the last few blocks before I get to my destination.

Just a habit, I came up with some theory when I was younger (regarding cages) about keeping the oil flowing for equal cooling and lowering the risk of brake discs warping because the pads held the heat if not cooled down or something. Not sure how accurate it is.

[Colapop]

The whole reason why NZ Post has CT110's is because they're pretty much indestructable. They must get absolutely thrashed and they still keep going.

you sure you don't want her to come in a smack 'im?

Last time I saw them - Stroud, Sherrifs and co - just entered the pits and shut off their engines.

[Oakie]

That's what I was going to say.

[Squeak the Rat]

I just consulted the bikes manual, and waddayaknow it don't say jack about cooling down.

Ya man's got heamorroids on his vocal chords.....

[N4CR]

With a highly strung 250 like mine I cool it down after mega thrashing periods. The sort of ones that make it drip oil.... and the exhaust ticks.. and the whole bike ticks.... and the exhaust tip changes colour. :whocares: Those far and few between runs are when I let it cool down for a few minutes. Poor bike....

It actually heats up if you leave it idling and the fan comes on after 5 mins... not doing any good for it - if you are riding normally, eh? Happens with most bikes as far as I know.. so you ain't helping by letting it sit.

Turbo warmdown is to stop the oil in the turbo bearings getting very hot while the parts are still hot, when flow stops (eg engine turns off) it will congeal and get crappy.. causing bad lubrication and wear etc. Don't really apply to normally aspriated bikes in most cast but I'm sure some NA race cars or bikes get warmed down too. So they run the engine to let the oil cool down components inside the turbo and exchange heat with the air via oil cooler etc untill it reaches some certain time or amount of temperature.

[Zapf]

cars cool down... and I can verify that by all the fancy gauges I had in my last car... but bikes heat up... as the cooling systems in bikes really rely on air moving thru them, cars too but to a lesser degree

[TONO]

exactly.. this guy has 'had his license for 32 years', and he 'is right no matter what, cause i've only been riding for 3 months..'

.

Well I have had mine since 1967 or 39 years so tell him he is full of shit.:yes: :gob:

[MattRSK]

Huh I voted for letting the water cooled bike have time to cool down. Dont know why????

[Back Fire]

I rode my 125 single cylinder 4 stroke, air cooled dirt bike non stop, at a constant 100km/h, redlining top gear for 300ish km's... was about 3-4 hours non stop... turned it off straight away as soon as I got to my destination... the exhaust ticked quite a bit but other than that it actually seemed to run better the next time I rode it (which was 300km's non stop back home the next day)

[Ixion]

Um. Given his age there IS one old time thing he might be thinking of.

The old Briddish iron had dry sumps. Oil in a separate tank, and two oil pumps.One from tank to engine, other pump to pump it back.

If you thrashed some of those bikes hard for a good distance, the feed pump would sometimes get ahead of the scavenge pump. So if you stopped quickly and just turned the engine off, the crankcases were left full of oil, which was considered a Bad Thing.

So we used to let the motor idle for a minute to clear the oil out.

That's the only thing I can think of.

(actually I tink it was caused by oil frothing so the scavenge pump became inefficient. But whatever)

[Brett]

Most bikes are reliant on air cooling as the main form of t loss, thus idling them is NOT going to help cool them dwn too much more.

[Pancakes]

I agree with everyone and not your nob-head collegue, If I have been holding the revs up and having a bit of fun on the way home I'll ease off on the last few streets. Plenty of air-flow, the oil still being pumped around so there's no hot spots and crap, even thats the last maybe 2 minutes of a ride. You should do a "warming up" poll and make sure you include all 6 million options so everyone can tick the box they choose!

[Lou Girardin]

No one has mentioned Buells. The fan runs on for a while after they're switched off in order to cool the rear cylinder which is well shrouded by the frame etc.
Otherwise Mr 'Riding 32 years' is full of shit.

[Wolf]

I've been having a great giggle reading this thread. Had never heard of a "cool-down period" before, but WTF do I know, I've only had my licence for almost 25 years, so obviously I must defer to your workmate's greater knowledge (Tui Ad in there somewhere).

I've always just shut the bikes down - and that includes immediately after lengthy open road rides when the bike has been so hot you can smell it and you hear the metal bits ticking as they contract.

[Storm]

The dude should be in politics- no idea, full of shit and a steadfast refusal to even consider anyone else point. Tell him to run in the next election
