Do you warm your bike up before heading off?

[CookMySock]

I never warm it up. Modern engines in good condition need about 2-3 seconds at the outside before they have full oil pressure to the main bearings. The main bearings MUST be oiled fully before loading them.

Choke, stand, ignition, kill, clutch, start! and as soon as it fires quickly before the engine revs build I whack it into first gear, let revs stabilise, then ease clutch out and ride off 4-5 secs max. Ya gotta be quick tho, or else the revs build to 3,000rpm then first gear goes in with a hellava MUNT.. sounds too harsh for me...

Also have to be really ready on the clutch, because you will have 3-4000 rpm on and the bike will want to GO!! Vtwin 650 does anyways, hehe.

Having said that, I barely touch the throttle for nearly 3-4mins and I keep the revvs under about 4,000rpm, and throttle openings tiny - just blip it up gears gently. Within 5 mins I am on the open road and I have a few bars on the temp gauge, choke fully off, and up to 100-115k/hr. Sweet as. Goose it, but don't cane it for another 5mins or so (this time can vary lol.) Vtwins lurrrve being goosed heh.

This 5-20min warmup thing is just pedantic bullshit IMO. If it makes you FEEL BETTER then do it, by all means - thats a good enough reason.

Modern bikes are designed to be started and ridden (or so the manual says).

If you thrash the bollox off it whilst the engine is still warning, it won't last too long.

Common sense and all that good stuff.

I have never warmed anything up in general.The car or bike get warm in the light running after startup and take off. For me with a Guzzi, if I warm it up, only the engine is gonna get wamr anyways... the two drive boxes will remain stone cold until the bike gets movin.

I can see some reason in warming, but then I dont.

I have a Celica of which, never ever warmed up except for being in action. over 330 thou km's and still strong. hell and some of those warm up running on the move, were not exactly gentle.... lol back in my young days.

Funny how one thinks if the bike is moving that equates to the bke being thrashed.

Whats the difference in the bike sitting still and motor doing 2000rpm (choke on) and the wheels going round and the bike doing 3000prm?

1) oil viscosity...
2) the pistons expand at a diferent rate cos their diferent metals to the bores/block and therefore while everythings cold their rattling around in the bores etc etc.(at least on the modern "hyperbikes")

cant say that a 10k launch dead cold would be much good for anything....

I understand oil viscosity. and dismiss point 2 on grounds of my first quote. comments on my second quote?

[FilthyLuka]

Yep warm it up in the time it takes to have a ciggy

If your real hard core you light the ciggie with the exhaust...

there is no diference... that counts as warming it up no...?
although my bike does idle at 1200rpm

[duckonin]

A cold motor needs a lot of battery power, not so much a warm motor...Why do some motors have to be decompressed to fire up cold ? but not when warm..

Basic Q's and A's really

[skidMark]

Let it warm up till its off choke...lid etc on..so gets 2 mins or so.

My zxr i did oil and filter change every 4,000 k's...

Except the timei let it get to 5,000 then did a trackday.

It went bang.

[avgas]

Yep - i wait the 3 seconds it requires to move warm oil all around the engine. At 5 seconds i'm gone.
I really would like to see someone ride off with a cold engine. That only worked on my RG150 bump starting it. and sure enough 5 seconds later it had started warming.

[Jiminy]

I warm her up.

On my old bike, a little too much throttle before she was warmed up would kill the engine. Not user friendly if you're taking your first curve of the day.

She warms up in less than a minute, I can hear the engine settling nicely. That's about the time for me to put my helmet and gloves on and close my jacket.

[saltydog]

The R1 likes choke every time, the carby model sits about 2.5-3rpm while warming up. By the time I get the helmet and gloves on the note of the bike has changed the temp guage has gone to 40C. Get on and ride her off the choke, gently, down until I've got her on the throttle. By now shes 46C, look left, look right and we're off at 50C.
Every time just like a ritual.
She cruises 78C, 5000rpm @127kms, redline at 11,000. When shes hot, up until 102C the fan kicks in and brings her down in temp, whereby at 95C it cuts off again.
Thats my baby. I've just been sussin her cooling out.....but yes always warm up

[BadCompany]

I can't be bothered reading the already three pages. But incase your wondering, at 6.10 I start the bike up and give it a little rev to keep it alive. Then I bugger off, brush my teeth grab what I need for the day and gear up. Then ride off about 6.20. So ten minutes of warming up, and the difference is very noticeable, much smoother and more responsive take off.

Oh and I service every 5000k's

needs a lot of battery power for what ? starting do you mean ? I would not think so, unless it was old or something was really wrong with it and it was really difficult to start.

Why do some motors have to be decompressed to fire up cold ? but not when warm..

Well, they don't really. It just makes it easier to kick-start them - not so much force required on the kick-start to boot the bitch over.

Yep, $1.75

Maybe you misunderstood the question.

The question is whether you leave your bike still to warm up before riding it. I say it make no difference but I am not advocating thrashing or even revving it hard as soon as you start riding it. just riding normally. There are cases (one just above) that leaves his bike for a full 10 minutes to warm up.
