First plug chop after carb rebuild and adjustment

Update: I pulled the carbs again, dipped and then boiled in lemon juice and water mixture (aka lemon aid) as Steve said . After much consultation I kept the main jet at 120 given my set up it seems to be enough, I lowered the pilot jet to 40 and put in a 170 air jet. 2 3/4 turns on all air fuel screws. The bike pulls hard up to 9k now. It seems to have much more power down low and top end idles for the first time ever. I'm sure it's a combination of the vacuum leaks fixed, floats readjusted, new plugs, caps, coil relay modification proper jetting. I just wanted to post this incase someone else wants to reference it for jetting size or other issues. Thanks again

Blimey you certainly know how to ring the neck off an old skool motor. I wouldn't take mine over 7,000 but each to their own.

Yes, at that level the carbs are working flat out and you could be suffering a momentary shortage of fuel. Could be float levels a little low? Or some restriction in the flow of gas?

The stumble is telling you that it's running out of breath and you need to back off a little!

thats when it's just getting warmed up. I'm going to take the carbs back off and reset the floats a little
Lower just incase they are running out of fuel

Add a fuel pump..........

OK - still the same resolution I think. You should be checking your ignition system.

It doesn't sound like a carb issue at the rpm range, however, raising the needles is free and worth a try.

I I took it on a test ride and tried a frw different things, at WOT is when it stumbles, if I slowly roll the throttle to redline it doesn't stumble at all. Times like this I wish I had a GOPro to film the riding when this happens

sorry for the misunderstanding it is not fixed those were the issues leading up to the hitting wall issue. After that I am currently trying to figure out that last issue

I believe the golden hue is a sign of richness, blue pipes are lean condition also some metal naturally dis colors but mine were gold

Gold (or straw) is the condition of hot metal, blue comes next then purple. It's progressive.

Got it all cleaned up and back together it's hard to tell but the pipes were golden and now it has slowly went away

What a beaut, I have an 850, Identical. is this consider Cosmic Blue?

What does the golden hue mean? My pipes have slowly gotten the golden tint in the past month. I feel like the bike is running hot, but not sure if that's related to the 100 degree weather. I'm scared that it's running a bit lean, which is causing it to run hot and turn the pipes gold. Are golden pipes a sign of running lean?

The nice golden hue has went away on the pipes, I have checked mileage yet. I needed an ice cold beer after this fiasco today. What would cause the 8K stumbling?

So it's fixed? Good to hear.

For what it's worth it was a very strange symptom of hitting a wall and then coming good at that rpm range to be a carb issue. At 8k rpm the carbs are pretty much using the full main jet so there really is nothing that would change in the carbs for that symptom to occur.

I should of mentioned that before, basically the events were I bought the bike almost two years ago. Rode the **** out of it. Then in the last month my mileage started suffering so I assumed it was a carb problem and I saw a gas leak from the fuel bowl turned O-ring issue.....carbs rebuilt new o rings in boots and carbs and gaskets, same jets and other set up is all the same then this issue started . All this time It actually was a bad spark plug from oreillys ���� the carbs needed cleaned and rebuilt anyways.... So now here we are

Possibly, that or the vacuum synch is out. Good to know the bike was running real well before you did the carb rebuild, at least you know the jetting change was ok.

Didn't you say it had bigger jets before?

If it ran well with them.........
