You may want to check the basics before you adjust the idle speed. You could just be covering up a bigger problem. Make sure you got 4 good plugs and that the carbs are clean.

Maybe run an additive through the gas and see if that helps.

Is the engine warming up fully?

Back to basics...Good start..

The carbs on the GL1200 need to be sync balanced prior to setting the curb idle. Perform the quick / easyinspections first.. Plugs cleaned and gapped, fuel filter, air filter clean,(I found a rodents nest inthe air filter boxduring theearly fall on a GL1500 last year). Also inspect for vacuum leaks which would give a lean mixture causing the idle to become irratic. Is the fuel clean? An additive is an excellent idea to freshen the fuel. Last but not least, what weight oil is in the engine? Heavier oil will cause a slow start and low running rpm this time of year until it obtains operating temperature... AFTER all is said and done, it may be time to look deeper into the engine timing, pilot screw settings, timing belts etc..Good luck.. Welcome to the club! :clapper:

Didn't see the "fuel injected" note... That's a different perspective.. What's the year and model of the bike and how many miles on it?

If you have new plugs in already then why not just turn the idle secrew in and bring the idle up. This time of year can see the tickover drop with the cold anyway and you need to compensate for that.

Danny, are you just unsure of how to adjust the idle? If so, just look in from the right side rear of the engine and you will see a big screw with a slot in it. Thats the idle adjuster.

:Xhi my neigbour just brought the workshop manual

i had not used the bike for a little while when i went to star it the battery was flat

so i thought i know i use my 12volt booster i could kick myself now

i just glanced through it and at the back it say's not to conect a battery charger to it

my bike is an GL1200 LTD

1986 FUEL INJECTION now do you think i have done any damage to it or is it a

coincidence that the idle as slowed because of the cold it seems to run fine

What weight oil did you put in the engine when you changed it?

If you blew something with the charger then you would know, ie the bike won't start or will only run on 2 cylinders or something disastrous along those lines. Why not just bring up the idle as suggested and see how it runs. It's the quickest way to test it and you may be fretting about nothing.

I agree with Ted. No point in thinking about other areas until you have done the simple job of upping the idle with the screw. If it doesn't stay up then its time to look further. Always do the simple things first. ;)
