Title: How long do you take to warm up?
Post by sexombob on 12/07/10 at 17:35:37

It'll take a little more than frost bite to keep me from riding... however, i've got a pet peeve... waiting for the engine to warm up in 32 and below.

How long is it suppose to take to warm up?

I usually wait a minute with the choke on and then ride off, but i have to keep some throttle on constantly so it doesn't shut off. Takes me a few blocks before it can get warmed up.

Would increasing the idle speed help at all?

I assume you mean until it runs ok. Everyone will have a slightly different answer. I crank mine and then put on my gear as it warms up slightly blipping the throttle occasionally to make sure it stays at good rpms. The difference comes here. after pulling out of my drive it is one mile to my first stop. (Either way) After that, choke in, hammer down. For those of you who have a stop sign at the end of the street it will be different. Also depends on your carb and the way it's tuned, I guess.

You could raise the pilot jet a size or two, then the engine won't be so cold-blooded.

Yes i mean when until it runs without shutting off.

@Boule
How many sizes should i go up? Currently its all stock, '97 Savage. Changing jet size may be an option but the way i ride, it would probably be worse off for the MPG.

Boule'tard, (And members) let me ask you. To me, the metal needs to be brought up to temperature slowly regardless of how well it runs right off cranking. I let my fuel injected cars warm up a little in winter. Am I anywhere near correct? (I'm still gonna' do it, though.) :-?

I've heard from someone that twisting the throttle from a cold start is very bad for the engine. I think there may be some truth to what you're saying.

Do you plan to uncork your airbox or exhaust? If not, I'd start with just one size up. But since jets are cheap (JetsRus.com) you might want to spring for +1 and +2.

Yeah, but riding around gently should be a gradual enough warm-up. It is not necessary to sit there idling with the choke on once the engine is running smooth enough to take off.

It usually takes me 3-4 minutes of waiting while it idles. I'll usually start the engine, and then put on my gloves and helmet. Then I sit on it for a minute or two, while testing the engine sound to make sure I don't hear it struggling and losing power while revving.

If I hear the engine struggling to keep up with the throttle while riding, I avoid revving it until I feel the engine warm enough to have power.

I take off choke as soon as possible. Usually within a minute of startup. Then I put in my gloves, helmet, adjust glasses. Usually takes 5 min. By that time, I ride away slowly. In my fuel-injected Jetta's manual it says and I quote "the best way to warm up your vehicle [upon staring on a cold winter day] is to drive it."

But that's fuel-injected so idk.

Before doing anything to the carb, try running with the petcock in prime position in case you have a stiff diaphram starving it for fuel when cold. 8-)

I'll start it & play with throttle & choke till I get it to idle,Then I roll away gently, accelerate slowly & gently, run it to a high enough rpm so it wont be lugging at all when I get a gear,, nice & easy.

I let my bike warm up with the choke out for a couple mins. If I need to rev it a little I do, yet make sure I don't overdo it. Like others, I finish putting my gear on in the mean time. Our driveway is a lil steep and gavel. The last thing I want is for her to stall going up to the top of the driveway. :) kim

I suppose I am in with most here with a little variance.....crank with choke on - put on coat, helmet, glasses & gloves roll to bottom of driveway in neutral - choke still on now at 3-5 minutes post crank......if it is in the 40's i take the choke off and drive away nice and easy never over 2-3K rpm's to 2nd gear in the neighborhood to the main road about 1/2 mile with several turns......if it is in the 30's i leave choke on until i get to the main rd.....if it is in the 20's I leave the choke on until I get to the first stop light about 1 mile from the house...all the while keeping the rpm's around 3k or less......even after that initial warm up distance and farther i dont "get on it" unless the air temp is in the upper 40's or over 50F......

I can tell you that after doing the 1/2 white spacer mod, it not only corrected the lean light throttle surging that I had, but it also made for less choke when cold. But no,...you don't do a white spacer mod for a less choke reason ! And if your bike is normally running good in all ranges, it rightfully will be quite cold blooded on a freezing morning.

On the other note, the engine does not mind working a little during warmup,......so if you think you're doing any engine a favor by standing still wasting fuel, rethink ! Warming up simply means limiting rpm's and load for a few minutes.

If I road when it was real cold I would put in one richer low speed jet. But 60 degrees is pretty much my limit know.

Post by Howitzer on 12/08/10 at 12:35:49

As far as I can think of, warming up the engine basically involves two important things: evenly heating up the engine block, and warming up the lubricant(motor oil). If the inside of your cylinder is hot, and the outside is cold, the expanding hot parts will create stresses on the cold outside parts. This is bad. If your lubricant isn't warmed up enough, it'll be too viscous, and won't properly coat your cylinder. This leads to higher wear.

If you rush the warm up process by using the throttle, you'll heat up the inside of the engine very quickly, before that heat gets a chance to spread to the colder outsides. This causes the thermal stress I mentioned above.

That's not to say *any* throttle is bad during warm up. You just can't have too much.

I ride in the frost too. However what I do is, and that applies to any weather, I pull the choke half way and crank. I let it idle for about 30 seconds, then push the choke back in. needs a little throttle not to die doing that and then keep it at 1,500rpm until the cylinder starts feeling warm to the touch, Then I drive off relaxed and shift at 3,000 for another mile or two. Routy is correct: when I shaved my white spacer, it had significantly effect on the choke. It needs waaay less and less time. I never need more than half choke. And I never need the choke, unless it drops to below 50 degrees.

What does the white spacer mod do? And how can i do it?

The white space mod raises the needle that's in the slide to open the jet up providing more fuel.

See the tech section idex.

Thanks i will definitely try this. However, i am confused as to where the low speed mixture screw is hiden. Is it the brass thing to the right of the idle adjustment screw in this picture?

By the way, the Owner's manual says the bike should be warmed up for "10 minutes in the summer and 20 minutes in the winter."

...it also says, and I quote (I think it's pretty funny) "The carburetor is factoryset for the best performance."

LOL

I've owned 2 LS650s ... an '03 and an '05 ... both were stock as far as engine/carburation/exhaust systems were concerned and neither was Ridden thru the winter months (too much snow/ice up here) and the cold start procedure was same for both and worked flawlessly ... pull choke knob all way out, crank Bike (stared right up every time), immeaditely push choke knob in 1/2 way, pull on Lid and gloves, Ride Bike gently from house down as far as gas station on corner (1.0km/0.62mi exactly), reach down and push choke knob all way in. Ride off as normal because Bike is now warmed up ... this worked for me regardless of air temp.

So lately i've found out that i can warm up the bike for about 2-3 minutes with choke all the way out. If i push the choke in fast, the bike dies. HOWEVER, if i push the choke in SLOWLY, it continues to idle! This is an amazing discovery for me (Haha). Stock bike btw!
