Bike Warm up

The other day at work one of my coworkers gave me a small lecture how I can wreck my bike because I start it and just go with no warm up. I drive a 125r and usually just start my bike, put on my gloves, get on the bike and go. I don't typically drive fast for the first bit, I keep it under 5000rpm until the bike gets warm.

So anyways, my question is should I let my bike warm up and for how long? Do you members warm up your bikes?

Cheers

Did your bike come with the owner's manual? If so, it will provide you with the proper procedure.
 
Yeah it came with a manual, I have yet to read the whole thing. I am just wondering what other people do. I know carb bikes need a short warm up because of the choke or something.
 
I always let mine warm up till it gets a reading on the Temp display (around 37^C).
It won't hurt anything in the short term but it is harder on the engine.
 
It's a lifetime-long debate, whether you should warm up your car or your bike, I have seen reasons for both sides. Carburetor-based ones obviously require a proper warm-up. Injector-based ones - that's the basis for extended and heated debates on many forums. Personally, I'm in the same boat as the previous poster, I usually let the bike warm up a bit, get the temperature reading, RPM will also go down slightly. All in all, it takes less than a minute, while I am putting on the helmet and the gloves. For me, it's a matter of personal experience, and that's why I'd do it, whether someone likes it or not.
 
I will sometimes let my bike warm up on the colder days in November and December, but either way, I just ride gentle till the bike is warmed up. I have never had anything wrong with any engine on any bike I have owned and would not be worried about damaging your bike when you start it up, just don't be redlining it, which you said you don't anyways.
 
I always let my bike get to operating temp. before I head out. I usually just let it idle while I get my gear on.

Definitely wrong. cold idling promotes carbon buildup, and uneven warm up - your cylinders will be warm, but not your gearbox/bottom end.

Do exactly what you've been doing. Fuel injected engines require minimal warm-up before driving off. Until it's warmed up, it is best not to use high RPM and full load, but running it under some load (driving gently) will warm the engine up faster than just idling, and that's better for it.

So what would be a solution to this dilemma?

hehe my 90 FZR600 wont even get out of its own way until its properly warmed up. Runs like utter garbage until its good and warm. Partly due to the carbs being out of sync, but big part that its carbed in the first place.
Hopefully getting them synced friday will shorten my warm up time
 
my 02 cents...

It's not so much about the engine being warm, although dumping a lot of heat into it right away is bad, so don't right hard right away. But it's more about the oil. It takes time for the pump to pump it up to the head, and I prefer to have oil circulating through the engine completely before I really stress it at all. I can hear in my car, start it, and you can hear the valves. I won't go until that quiets down and I know there is oil in the head.

more likely running on enrichment too long/not long enough. or it's just not working. carbs are great - when running right.

just being pedantic, but you're not hearing valves, you're hearing hydro lifters. and if they're clicking until oil pressure comes up, they're tired and leaking down when the car's off. which means they're leaking when the car's running, which means you're down on power because the valves won't be opening to full spec.
 
most camshaft LOBES do not have oil until the engine revs up and splashes them with lube. one of the highest pressure points for lube is the camshaft lobes. for the least amount of wear on the camshaft lobes,, it is best to drive away as soon as you start the engine. causing the most amount of oil splash . for older flat tappet engines.. this is also a place to have zinc in the oil ... roller cams don't have this issue as much.. but do need splash to lube them. as said.. carb engines have issues with stalling until warm,, and that makes riding a bike tough when cold. most other parts in an engine have oil under pressure to keep them rotating nicely,, and once the pump starts .. the parts are lubricated,, cold or warm..
 
The cbr125 oil pump pumps plenty of oil to the top end, even at idle.

Ask the guy who forgot to tighten a valve cover bolt after a valve clearance check. Oops.
