Greetings all,
It's been a few weeks since I was last online here... much has changed in life, and I've been struggling to stay on top of everything... But it's quieted lately, and now I turn my attention back to my 81 GS1000.
I have a couple of questions I hope you all can help me with... If these have been answered elsewhere, I do apologize, but I didn't see anything related to the idle mixture screws, apart from broken needles etc.
First - I got the GS1000 running, but have a major problem. It will idle just fine, a little rough at first but once it warms up the throttle response is immediate and there's no hesitation before returning to idle speed. When I took it on the test ride, it would not accelerate. Acted like it was bogged down and struggling to run. After a few minutes of riding I was hoping it would have warmed up or whatever the hell it needed to do but it only got worse, I was told later by a friend who passed me by, my right pipe was spouting black / blue smoke.
There are no issues with that cylinder - cursory inspection shows no scoring of the walls that would indicate a broken piston ring, and there does not appear to be any oil in the cylinder that would burn and blow black smoke. I had this problem before when I was... ashamedly, trying to set my idle mix with a carb sync tool.
It was early on, and I was still learning what I was doing with the mixture. The result was one way overrich cylinder and others in varying degrees of wrong.
This makes me suspect it is an issue with the #4 carburetor, as this is the one that had the snapped idle mix screw tip stuck inside, along with stripped screw top. I had to drill the screw and remove it very slowly and carefully, and was able to remove the stuck tip with no problems. The screw that I have ordered THREE TIMES NOW is very different than the one that came out... Which leads me to my next question.
Second - The idle mixture screws that come with these carbs are pretty uniform in design, tapering down a point with no shoulders or deviations. The ones that I keep ordering from the dealers are brass, not stainless steel like my old ones, and the new ones have a second shoulder leading to a more conical taper, unlike the originals which are quite obviously different.

^ That's what I wanted, but the damn dealer keeps sending me this brass POS. Could this be my problem? If so, can I replace all the others so they're all identical, or do I need the original? If I need the original where in the bloody hell do I get them? I keep ordering from different shops using what I thought was my OEM serial number, but keep getting these freaking brass ones! I called once, emailed twice, and by now they won't even reply to me - apparently I'm being unreasonable by asking for the correct dang part!
Anyhow, is this what could be causing the smoking and lack of power?
I don't currently have access to my bike, it's locked up in the shop, I've gotta go get a constable to get my things out.. (Civil dispute, yaaay) But until then I'm trying to identify the problem so that when I have the bike back, I can get right to work.
If you need more info, ask away and I'll provide whatever I can from memory or from notes.
Have a great evening folks, thanks for stopping by!
*I posted something similar in the GS1000 thread I started a while back, but I didn't realize it'd been moved, so here we are!
