The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Warm up opinion wanted.

I have a 78 GS750EC with a hair over 12,000 miles on it. The bike starts right up with just a bump on the starter button, and it idles beautifully.
The other morning with outside air temperatures at about 55 degrees I fired the bike up, adjusted the choke to idle at about 2000 RPM's for a minute or two while putting on my jacket, gloves, and helmet. I bumped the choke down to where the bike was now idling at about 1300 RPM and hopped on and took off. I noticed it was probably a full mile down the road before the engine seemed to be at operating temperature and I could shut the choke completely off without the engine dying. After this short warm up and the choke finally turned off the bike performs flawlessly.
I have had others tell me that the GS's can tend to be a little on the cold blooded side and some tell me that my warm up seems a little long to them. Of course those that are telling me this are riding much newer and more modern bikes.
Does what I describe above seem to be a normal warm up senario for many of you out there?
Thanks,

These bikes left the factory set up a bit lean and are hence, as you describe, cold-blooded beasts. Some bikes warm up quicker than others in my experience but that's 'just because they do'.

You could richen things up a tad with the airscrews but if it's otherwise running fine I'd leave it alone.
 
Most GS owners twiddle the idle mixture screws slightly richer. This also shortens warmup time and improves throttle response off idle a bit.
 
I live in Ohio and ride my 81 GS750 every day. I go thru about the same routine you do. I dont have a choke cable on mine so I get it started and then let it idle for a good 5 min while get my gear on, then I just run the hell out of it for the first 2 or 3 miles by then its purring like a kitten.

Yours is about the same as my 1100. Usually though after the two mins the choke is completely off.
 
Bikes with CV carbs will benefit noticeably from raising the needle; cold drivability is improved. Do a search for details on how to do this if you don't understand the process. For bikes with VM carbs, the drivability can be improved by opening the pilot fuel screw by 1/8 - 1/4 turn. Made a difference on my bikes anyway.

If your bike otherwise runs good then I think your doing it just right and wouldn't change a thing. The FZ1 board's motto and I think it a good one, is "Ride more, worry less"

Why live with an issue like this when a 20 minuet fix puts it to bed?
 
i have to choke mine every single time i start it, but by the time i hit 3rd or 4th gear i can kill the choke and she runs perfect.....
 
sounds in line with mine. .takes a mile or two to get it going.. sometimes a hair longer ,depending on how hard i hit the throttle early on.
 
Exactly the same for my 83 750E. A minute or so on full choke (enricher). dial it down to 1/3 and ride away. A minute later and choke off. Its the same summer, winter,fall and spring. Once its warmed up it fires first button everytime.

I wouldn't fart around with it as it seems normal to me. When you get to playing with it you stand a chance of making it worse:eek:

Fire it up and ride man.

Cheers,

There are three bikes here that get ridden somewhat regularly and surprisingly, all seem to survive on the same technique.

After some considerably experimentation, the "sweet spot" in the enrichener lever position has been found. Seems to be just under half-way on all three bikes. Set the lever, start the bike, verify that rpm is not over 2500. Put on helmet and gloves, back off the enrichener to keep rpm under 1500, head on out. By the time we are in second or third gear, 'choke' is turned off completely. This is regardless of ambient air temp. If the bike is still warm from a previous ride it will likely not need any 'choke'.

Oh, the three bikes? My Wing, wife's 850L and son's 850G.

ok joke time...

One GS rider said to another, "sure is warm out today" the other replied, "yeah, no choke" hahaha i thought of that as i rode of into the very cold afternoon
