warm up time

[Anonymous]

How long does everyone's bike take to warm up, mine seems to be taking longer since I corrected the ignition timing, which was way way off. Also, what's everyones policy about riding with the choke on for a minute, do you or don't you, I've never gotten a clear answer.
BTW, I'm riding a 78 gs1000ec

peace

Ill bet you get a million diferent methods here
I start mine with full choke when it has not been started in any given day--then i let it go t about 3K and cut it back to 2500 and a minute later back to 2000--I let it run for just another minute and reduce the choke till the idle comes down to 1000 rpm and someimes i goose it with the throttle to see if it is taking the gas-- Next move is put it in first and go a bit at a verymodest speed. My temperature guage
doesnt move for a few minutes after that- and the bike doesnt get oil up to 200+ degrees for almost 45 minutes--same proceedure all year round- i dont ride if the OAT temperature is below 65 to 68 degreesF--after the first startup i never use the choke(or almost never)

My starting procedure is to pull full choke, and start the bike, set the choke for about 1500 to 2000 revs and then I go to put my jacket, gloves and helmet on. THen I attend to any baggage and futz around a bit with my sunglasses and watch. By the time I sit on the bike it is usually ready to go. About 8 to 10 minutes warm up and then take it easy until I hit the first stop sign. On a return home from work, I choke the bike, start and go after about 5 minutes. If the bike is warm I don't worry about warm up time.

I usually start with full choke and then idle down to 2500 rpm's for a minute or so. Then like Gerryy, I take it easy for a few minutes or miles before I get on the throttle to any degree.

That is just how my bike does the best, yours could and may be totally different.

Out here in sunny California (big sun..even bigger taxes!) I usually choke it slightly for a minute or two. I think if warm-up time takes more than 3 or 4 minutes, it might indicate that the bike is running lean. I know I had such a problem right after I rebuilt the carbs. I backed out the air screws and cut warm up time to a fraction of what it had been. 8)

I start full choke then back it down to 2k and let it idle for about 2 minutes ..then I press in the choke and ride off....A bit longer when it is very cold out

I use the identical method as Gerryy to start my bike.

Hmmm, I thought it was bad news to let your bike idle for longer than 5 or 10 minutes on air cooled engines. It was my understanding the jugs could get really hot and with a lower rpm, the oil cooling isnt' very effective.

I just set the choke,start it and go.

I pull the choke out about half way and throw my clothes pin on the rod and push it back in. Start the bike and let it idle down to about 2000 rpm. ( know I'll catch hell for this part) then I have a smoke. By the time I'm down the bikes warm and I take off. The clothes pin is there as I park in a pay lot at work. The lot closes at 9 pm and they stick a small envelope under the windsheild wiper of the cars to put your money in. They use the clothes pin to stick the envelope to my windsheild. This changes as the weather gets cooler I have to use more choke.


What you have to do is figure out how to best start your bike. Remember cooler weather will change the way its done. Well on my bike and I imagine alot of others.

Hey JB
maybe your clothespin trick is what i will do for my new carbs--it sounds perfect

It depends on the air temperature, but I usually just use 1/2 choke to start my GS1000 and leave it on choke for no more than 10 seconds (remember, the longer its on choke the more fuel you use, and the more likely it is for oil to be washed off the bores by the excess fuel). I like to get moving pretty quickly (careful going into 1st gear!!!) but don't rev it above 3500rpm for the first couple of miles. After that I add about 1000rpm for each extra mile. This seems to work as when I inspected the bores on my last GS at 60k miles the original crosshatch hone marks were still visible and there was little or no sign of leakage past the rings. A mechanic friend of mine could not believe that the engine had done more than 20k.

I use full choke to start it, cut it back to about 2000 rpm or until it starts to miss and then smooth it out. I let it idle for few seconds and keep cutting back until it will hold a steady idle of about 1000-1200 rpm. Then like Scotty, I check throttle response, and if it's good I ease out for a ride. I've got a mile of quiet road to warm it up as I go.

I won't comment on how to warm up an engine because I don't do it properly but as for riding with the choke on... I wouldn't. If you ever pulled out of your driveway neglecting to see a car your response would be to gun it when you did see the car but you could get flattened since the bike would just bog out.

My bike is not standard, so procedures may vary. Also weather here varies between -10c and 40c...so depends on the time of year!!

Usually, choke full on to start, let it settle into a 1500 or so idle (whatever is steady)..I have lumpy cams etc so a bit different to std. I put all the bike gear on then get on, turn choke off and ride off keeping it below 3000 or so until it warms up. For most riding below 4000 is plenty anyway (keeping to speed limits, which all on here do I am sure with such an old veteran bike!!)

The bike lets me know when it is warm enough as the fron starts lifting up with a bit of throttle......

Standard emissions legal bikes may need a bit of choke for a while to stop the staggers.

I have had the old girl for 22 years, so we have a relationship.......

warm up period

warm up period

i start my gs750es with full choke if its the first start of the day. lean back
to about halfway(2000-2500 rpm). leave it there while i'm putting on my helmet and gloves and then lean it back slightly and hit the road. less than a mile down the road the choke is switched completely off. letting it warm up any longer than that unless you live in a cold climate would be overkill.
if the engine hasn't warmed up enough in that time you have a problem.

Re: warm up time

On my 750, I pull out the choke, start the bike, and let it run for about 10 seconds, and shut off the choke. Then I let it idle and warm up for 4 or 5 minutes before I ride away.

Hi Chev,

The choke question depends on what type of carbs you have. The Mikuni vacuum carbs use a starter jet, not a choke. It only operates at low revs by picking up extra fuel from lower in the float bowl through a separate jet. As you increase revs the fuel comes through different jets and the starter jet is merely a small fish in a big pond, so to speak. This means that the mixture is rich at low revs but as the revs pick up it gets to normal burn.

On carbs where the choke operates a butterfly you will richen the mixture not only at low revs but right through the rev range. It is this type of carby that bogs down if you have the choke on after the engine warms up and you open the throttle too quickly.

Normally you only need the choke until the bike idles OK at rest or, if you are moving, pulls away OK at low to mid revs. There is nothing to be gained from sitting in the yard warming the bike up to operating temperature if you could be riding it already as it warms up. The only thing to keep in mind is not to conflabberise the motor by gunning it too hard while it is running cold.

Kim
Great new word, Eh? I wonder what it means.

I start my '78 GS750 with full choke, and almost immediately I have to shut it partially off to prevent the motor from revving to the moon. I adjust the choke so it idles nicely, and then slowly turn it off while revving the bike slowly. I don't ride away until the bike will rev cleanly with no choke, and I don't mean 9 grand revs, just 3 or 4. This only takes about 15 seconds or so, as the bike is garage kept, (naturally). For the next 5 or 10 minutes I try not to rev it past 4 or 5 grand until it warms up. 8)
