1989 GL1500 long warm up time

Post by jwebfournow » Sun Dec 03, 2017 2:30 pm



Hello all, I am looking for some information on this new to me 89 wing, this bike has been sitting for awhile, after putting in a new fuel pump, I can start it up using full choke it fires up great. runs at about 2800 rpm I can gradually drop the choke down to about 2300 rpm but I have to leave it on choke until it gets fully warmed up if I try to reduce choke anymore bike just dies. I guess my question is do these bikes take a long time for warm ups before you can take it off the choke fully. After the bike is fully warmed up it responds just fine no bogging or hesitation, I only question this because I have a 1984 gl1200 that I can fire up when cold on full choke and take it off choke after about less than a minute and it will idle fine. Just wondering if the 1989 GL1500s are that cold blooded, or it is just normal for them.

If you had given some specific information like the ambient air temperature, the time required for a smooth idle rpm without choke etc. it would be easier to comment on and compare it with our bikes.

There are two temperature sensors (air and coolant) providing information to the ECM to adjust the ignition timing, so a bad sensor might be creating a problem.

Personally, I will use the choke at full position first, after starting the engine adjust it to 2000 rpm and gradually reduce it. If the choke is too much, I can hear some sputtering sounds and it reminds me to reduce the choke amount.

i figure about 3 minutes, or just get on it and ride with the choke full on.
won't hurt anything,

in about a mile you can pull it all the way off.

sounds normal to me.

Thanks for the reply, been starting every morning probably temp is about 50 degrees, full choke is about 2600 rpm, then it starts to rise to about 3000rpm, which is when I Start to raise the choke lever to drop the rpms, if it gets to about 2000 rpm it will just die out even after it has been running for at least two minutes I then restart with more choke then bring it back down to were it will stay running usually that will be about 2300 rpm, this is were it will stay until it gets warmed up, after that its fine throughout the day maybe using a little choke if sitting for several hours, kind of thinking maybe could be a coolant sensor, will have to find it and test it

The test procedure of ECT sensor (Tw) for your bike is given below.

Since it is difficult and time consuming to remove the sensor, maybe you can try to check its resistance by removing its connector while the sensor is still mounted on the bike, at different engine temperatures.

Thanks Erdeniz, I will do the testing of the sensor, I have the Clymers manual for it but have not totally gone into it yet, I am really surprised the bike is actually running as well as it is, the bike as far as I know was last on the road in 2003, but I believe it probably has been started and moved a bit since then, my experience with bikes that sit like this has always been gummed up carbs, this one surprised me when I picked it up from the guy who purchased it from the estate of the original owner, I found the fuel pump was literally missing from the tank and was just covered by a piece of dynamat, so in when a used pump, with a little coaxing fresh gas some seafoam it fired right up and after awhile cleared itself out and is alive. It will be my winter project doing all the service work , timing belts, fluid changes etc etc, Since this is the first 1500 I have owned I am very pleased so far with the smoothness of the engine. I'll reply back with an update

If I start the bike before I get ATGATT in place,

I just pull the choke back to about 1800-2000 rpm when it reaches 3000

by the time, I get my boots laced up, it is usually ready to go and will idle at 900.

I had an 89, and now an 88. I would start both with choke on, then let it run for about 30 seconds. After that, I would reduce choke to nothing, and then "blip" the throttle. If it bogs down, I let it idle with no choke. Seems by the time I fully get my chaps on, helmet on (jacket is usually already on), bike is warm. No need to ride away with choke on.

Weren't there some service bulletins on the '88 & '89 about runability issues? Hard to imagine the fixes haven't already been done on almost 30 yr old bike, but.......

I think they were fixes to help out being notoriously cold-blooded on start, and stumbling on acceleration....
They say 98% of all Hardleys ever made are still on the road..... The other 2% made it home. :lol:

I did have it on my 89, was stuck up in Snoqualmie WA at an IHOP due to vacuum issue, had to put it on a flat bed and down the hill we went to the local shop, which fixed it pretty quick (1/2 day). I have not had any issues with my 88 at all (knock on wood) but everything was checked out when I purchased it so I assumed all bulletins were addressed.

I too have an 89 gl1500 that I bought last year after it had been sitting around for about 4 years. Everything that you just said, is what was going on. I tried fresh high octane gas, carb cleaner, and a bottle of fuel system cleaner. nothing helped. I read about seafoam on one of these forums,so I tried it, it has made a huge difference...I highly reccomend it

Also, make sure your hot air hose is connected from below the engine up the fresh air intake 'snorkle' at the airbox!

That actually made starting easy worse, high octane fuels are harder to ignite.
all Goldwing engines are specified for 87 octane or the lowest grade on the pump at High Altitudes.
The lower the octane, the more power derived from the explosion, and the easier it is for that explosion, wave front to occur. ( requires less high voltage at the spark plug to create an arc under compression. )

I'm pretty new to goldwings, and wasn't sure if I would like a bike this big, but I do love it. If that is low octane in high altitude, what about the rest? I've always put high octane in my small engines ie: lawnmowers, motorcycles. If the goldwing is a different animal then I need to know that.

high octane is not required in any lawnmower, it is a waste of money.
and it is not required in most motorcycles unless they are high performance and specifically state that 91 is required. If that statement is NOT there, use 87 octane, the engine will perform better. even at sea level.

Regular gas in Denver is 85 octane, I run that in everything (cars, jeep, lawnmower, chainsaw, bikes), the 1500 runs just fine on it. Very hard to find whiskey-free gas in Denver, you are pretty much stuck with E-10.

I just looked at https://www.pure-gas.org/extensions/map.html

and there are a lot of Pure Gas E-0 stations in the Denver area.

Maybe not handy for your own location, but at least they are there.

As I always use Pure Gas when I can find it, I have the Android app on my cellphone
https://play.google.com/store/apps/deta ... an.puregas

I have to have it for my Suburban now, I used an Engine Tuner to get more performance out of the 5.3L engine on 87 octane. Made a nice difference, was averaging 5.5 mpg towing my Toy Hauler before the tuner, and now it is averaging 8.6 mpg on the same exact routes as before, filling up at the same exact fuel stops every time. The Toy Hauler has a 40 gallon fuel tank for the Onan, and it also has a fuel pump with a gas pump nozzle to fill my bike from that tank.... win win for me.
