Choke - where am I going wrong?

Post by tegid »



GL1100 1983 - I have had the bike for just under a year and she runs well, however I have always had a problem starting for the first time in a day - once started no problems after that. I will admit that here it is a season of cold and damp but starting has always been tricky. For the first start I give full choke and open the throttle - she fires up, fades and dies. After that I have tried - choke, half choke, no choke, etc. and always very difficult to fire up again The only quick fix has been a little dose of "easy start" into the air intake (ether I think - whatever it smell interesting) She them fires up and then runs well after warming up. I have had a look at several topics on the site but no help I'm afraid.
One final observation - the choke control has been modified from a lever to a pull choke knob.
Any ideas? I don't like to use this "easy start" - I guess it can't do the engine much good.
Best wishes from a very soggy west France

After the initial startup and die have you tried a couple twists of the throttle before hitting the start button again? Works the accel pump to squirt a little fuel in the intakes... Leave choke on.

Have you replaced the spark plug wires and caps? That may be your problem. Cold moisture gets in any cracks and you loose spark power. Once warmed up the moisture is gone. I had to do it on my 83.
Most cycle shops carry replacement NGK spark plug caps and bulk 7mm plug wire(need 7'). With new spark plugs the total 9 years ago was $32. Probably up about $40 now.

I just read through your post again, and see you are in France, I'm in San Diego California so that is USD$.

Are you sure your bike is an 83? The picture you have in your profile shows a Comstar wheel on it. 1983 came with 11 spoke cast wheels not the Comstar. That would explain the choke pull vs. lever choke on the 83. 1982 had pull choke near the clocks, 83 had a choke lever at the left hand grip.
If you are going by what your title says, back then they may have titled left over bikes to the year they were sold in some countries.
Have you looked at the vin plate on the steering neck? That should have the year and model on it. Post a picture of the vin plate.

First of all thanks Denverwinger - the starting method works a treat. After thinking about it, I always had to pump the accelerator on some of the old cars I had in the past.
Newday777 - the wing is a 1983, I found this out when I first had the bike and discovered linked brakes! Bleeding linked brakes with a sidecar was an experience. The previous owner gave me the 82 handbook and linked brakes came as a shock.. The bike does have a lever choke that is disconnected; I guess that at some time the choke cable from an earlier model was canibalised to replace an existing cable. The wheels are not the originals, I assume these were changed when the sidecar was added, smaller wheels are often used on a sidecar rig, more torque to the road.
Thanks to you both

I.m on my 4th GL1100 and the starting works best is full choke, do not touch the throttle. it will go to about 4000rpm's or more then push choke until it is running about 2000 rpm's. Winter may take a minute or 2 until you can put it in gear and go.. Summer it takes less time but I never touch the throttle until it is running. Works for me.

Here in Pa. if the temps are 40 degrees or below I found this procedure works: Full choke & hit the button...bike will fire almost instantly, rev to about 3500 then slowly drop and usually die....twist the throttle a couple of times and repeat. After a few tries the bike will stay running and rev itself back up..when it does I'll slowly take the choke off and use the throttle lock to warm the bike up at about 2000 RPM with no choke.

I have been working through the suggested starting methods and by chance I tried something like the method Overdog and Dnehasert suggested - perfect start. Here the big problem is damp, west coast of Europe. -40° in Pa ! the lowest I've seen here is -6°C (20°F). I just had to do some unit convertions and did you know -40°F = -40°C ? damn cold in any units.
Best wishes and a merry christmas to you all

When it got down to 0degrees F. I would use 5w30 oil in the Wing and make sure your battery is in good shape and keep charged.

Thanks for all the advice the wing starts without a dose of ether!!! I'm impressed by the American style of motorcycling - minus 40. In my commune (yes we have communes) most garages seems to contain a high capacity motorcycle: these rest under cover until the temperatures is well above 70°F and the sun shines. And suddenly there are bikes everywhere. Now I am old, but my heart sinks when I see a born again biker, often middle aged, haring down the road dressed in helmet and gloves (legal requirement) and tee shirt and shorts (Looks cool but have they never had gravel rash).
This said I must not be too hard there are some real bikers in France that keep going in all weathers and show good spirit. Is it the same in the USA?

LOL...I said 40 OR below....not minus 40!!!! I won't take the bike out when it's any colder than that due to the threat of ice on the road.

Salut Overdog
And there I was thinking « God these guys are tough » and thought of you hitching the huskies to the Wing and heading out to the Klondike.
