GL 1200- How long for normal warm up?

Still "sorting out" my resurrected 1200. How long does the choke need to be on this bike, it seems a lot longer than my other Hondas. It seems to take 3-4 miles of driving before I can take the choke completely off, otherwise it bogs slightly and I get a lean popping in the airbox, once warmed however it's fine. It's still lean for a bit even if my water temp indicates 3 bars on the gauge, another mile or so then it is fine. Outside temp was about 50 degrees when i left for work this AM.

My gut feeling is I should have drilled the blocks ever the idle mixture screws and backed them out a bit. Hindsight is 20-20! as I recall 80's Hondas are lean off idle, on my CBX I shimmed my needles 1.5 mm and backed out the idle mixtures to 2.5 turns, and it has run faultless for years. Even though it is air cooled, I can run without choke in 1/4 mile.

Both my '84 Interstate and my current '87 Aspencade have been that way.

Very cold-blooded. Like you say, a good 4 or 5 miles of riding before the choke can come completely off.

I'll be interested in what other GL1200 owners say.

Do an idle drop and see if that helps.
Mine has never really been that cold blooded.

Why ain't we ridin'?

yep very cold blooded they are, I have routine, that helps, I carry my helmet, gloves, top coat out the bike, and place them handy. start the bike with about 3/4 choke, then bring it back until its idling on the choke, at about 12-1300 rpm.

put gear on, and by the time I pull out, it showing one temp bar, and I can turn the choke right off.

she still feels a bit grunty, but once 3 bars are up it all good.

Mine needs the choke for about 2-4 min depending on how cold it is. I have a 1/4 mile driveway and always have the choke off by the time I get to the road. Yesterday, I started my bike and let it idle about 3 min before the choke was ready to shut off. I wasn't quite ready but my battery was low and I didn't want to shut it off. I have great throttle response except when I shut the choke off to soon.

The LORD is my light and my salvation--so why should I be afraid? The LORD is my fortress, protecting me from danger, so why should I tremble?

Dennis, by "idle drop" are you referring to a idle fuel mixture adjustment, or just a curb idle drop, right now I'm perfectly synced and idling nicely at 1000 rpm +_ 20

And yes it pops in the air box easily 3-4 miles and a bit even when at 3 bars temp, a few MORE miles and then it stops.

I heard that 86-87 wings have even LEANER idle mixture settings than 84-85 Wings, true?

I start the bike with full choke on and make it 1/2 in 10-30 seconds (1700-2000 rpm). After that I smoke my morning cigarette, make the choke off and ride I never ride with a choke on. It's a magic morning procedure (starting, smoking, listening to ZZ Top). No hurry, no rush It's a Gold Wing!

This is from the 1200 Honda service manual. You will likely need a sensitive tachometer hooked up to measure accurately enough to perform this procedure. Once it's done, it doesn't tend to go out - you won't need to repeat it.

IDLE DROP PROCEDURE

NOTE: Use a tachometer with graduations of 50 rpm or smaller that will accurately indicate a 50 rpm change.

1. Turn each pilot screw clockwise until it seats lightly and back it out to the specification given. This an initial setting prior to the final pilot screw adjustment.

INITIAL OPENING: 3-1/2 turns out

CAUTION: Damage to the pilot screw seat will occur if the pilot screw is tightened against the seat.

2. Warm up the engine to operating temperature. Stop and go driving for 10 minutes is sufficient.

3. Attach a tachometer according to the manufacturer's instructions.

4. Adjust the idle speed with the throttle stop screw.

5. Turn each pilot screw 1/2 turn out from the initial setting.

6. If the engine speed increases by 50 rpm or more, turn each pilot screw out by a continual 1/2 turn until engine speed drops by 50 rpm or less.

7. Adjust the idle speed with the throttle stop screw.

8. Turn the No.1 carburetor pilot screw in until the engine speed drops 50 rpm.

9. Turn the No.1 carburetor pilot screw 1 turn out from the position obtained in step 8.

10. Adjust the idle speed with the throttle stop screw.

11. Perform steps 8, 9 and 10 for the No.2. No.3 and No.4 carburetor pilot screws.
