Hi all,



Back with another question. I rebuilt the carbs on my 76 GL1000. The bike is running again, but I have a question on the Pilot screw settings. The manual says to screw the pilot screw in until it is fully seated, then back it out "two turns".



My question; is it two turns (360 deg times two) or two turns (180 deg times two)? I have been using the (360 deg times two) method, and it seems like that is a lot for an initial setting.

For reference, I put a small bit of red paint on one side of the screw slot and count the turns 180 degs at a time for a total of four turns.



Can't wait to hear from some of the veterans out there.



Thanks

Paul

2 full 360 degree turns. 180 is 1/2 turn.

In my calculations:

one turn = 360 degrees

On my 1100 I've found it likes 3.25 turns out from lightly seated. So it doesnt matter what may seem like a lot... its how fine the thread is... a fine thread isnt actually backing out as much as a coarse thread would for the same number of turns.

If the bike likes it... then its fine. Does it idle nicely... and are the plugs the right color... those are the things to watch for. You may have to adjust your timing after setting the carbs.

Thats my .02 cents worth.

I need to do an idle drop. I've got a dwell/tach/volt device. How do I hook it up on my 12 to do the idle drop? I'm pretty sure one lead clamps to no. 1 plug wire but where do I connect the other lead?

Thanks.....

As I said, I used the 2 complete turns, and adjusted the idle, she seems to run fine. I do not seem to have any problems, although I think she is running a little rich. I want to get the timing set and the ctarbs synch/balanced. Then I will be able to see if anything else is going on. I use the choke everytime, although if it is warm andsunny, she does not really need it.



This brings me to another question, if I think she is running a little rich, do I turn out the pilot screws or turn them in to lean it out?

I don't know if your device is the same type as mine, but it does have the same functions. Check up here: http://www.goldwingfacts.com/forums/forum1/80256.html

O.K.,

Took the carbs off again, got the two broken pieces out, put it all back together again. While I had it apart, I discovered that one of the o rings had fallen off the bottom side of the air cutoff valve. Found a spare and got that back on. Put it all back together , pulled out the choke and she fired right up, revved up to about 4k, then started dropping. I tried pushing in the choke part way, but it dropped to stall. I pushed the choke in all the way and she started right up, gave her a quick goose and let go of the throttle and she settled into an idle, seems to run fine. I haven't had a chance to ride due to the rain.



If it does not require much choke to start when cold, is that a sign that it is running too rich or lean?



Thanks

In my opinion it should require choke to start and run cold otherwise it is too rich when warm to be efficient. Turning the mixture screws in may help but usually it's the float level too high that causes rich running if the jets are original size.

If I turn the pilot screws in does that make it leaner?



I thought that less air + more fuel = rich conditions.



Do the pilot screws affect air flow or fuel flow?

The screws adjust the fuel so in means less fuel, leaner.

Well that may explain a lot. Before I rebuilt my carbs, I was running 2 and 1/2 turns out. When I cleaned and rebuilt, I returned them to the 2 and 1/2 out, I will try turning them in a 1/2 turn at a time and see how it does.



Thanks

Paul
