It's idling at 2500 RPM without the Cap or Filter, with just Filter 4000 then with the Cap on it jumps to 5500 RPM instantly. And I shut er down. What it feels like is the more I Restrict what it can draw through the Intake, the more it's drawing through a Leak somewhere under the Carbs. Only Problem with this theory is the Plugs aren't suggesting a lean mixture. Their just Black, which in my admittedly uneducated Brain is suggesting slightly Rich.

Well, I'm also pretty sure the Cruise Control opens the Butterfly's, and their not moving when it Revs.. It's running better since I Synced and Adjusted the Carbs. But something that uses Vaccum to Rev the Motor if not functioning the way it should.

It has something to do with Vaccum, as soon as the Cap Sucks down it Revs up. I feel like it has something to do with the Cruise Control but I disconnected it a Month ago and no change.

Yes lol, I broke down and bought some starting fluid today and she fired off. But still doing the same thing.. Idles super High with the Airbox Cap on, Comes down some with just the filter and actually kinda runs ok with just the Velocity Stack's. But it's doing small Backfire's the whole time, and I know it has to be Lean..

Alright lol, I think I need some time away from this thing.. It is now refusing to start, it won't even sputter. I have brand new Plugs that have a solid Blue spark, new Air Filter, and Pilot Screws are set to Factory Spec, and it's getting fuel. It's almost like when I tighten the Plugs down they stop sparking. I think I need to take a step back from it...

Lol, I definitely Can. When Covid first Hit and I got basically laid off I started going Crazy try to adapt to not working 50 Hours a Week. So I found worn out 74 CB-750 and bought it for 300 bucks. Now I'm kinda addicted to putting Old Bikes back on the Road. I did an 82 XJ-750 Maxim Cafe Racer last year and went through Hell getting the Mack 4 into 1 and Pod's to work right. Now this Venture is giving me all sorts of Problem's..

Welp at least Today wasn't a total loss, It seems to be done Fouling Plugs. Might order a set of those Gauges and see if the Carbs are out of Wack. I don't think that's it, but I'm running out of things to check..

Nope no issues, I've never been so let down to find that all my Engine Component's are functioning as they should lol.

Ok, it's still Revving but not quite as high. White Smoke is gone Plugs no Longer Fouling. Running Rich though.

Ok cool, I'll give it a shot.

Made an interesting discovery.. I was looking over these rubber Tubes that run from my Head to this Black Box under my Battery, pretty confident their part of the YICS System. Anyhow, I was looking them over and turns out several of them have holes. Does anyone have experience with these tubes, and could they be the Source of my High Idle issue?

I'll check em out.

I have a Compression Tester, but I bought it for my XJ-750, and it won't work with the Venture.

But I have really no idea, never seen anything like it. So that issue is on the Back Burner, and I'm getting ready to Pull the Heads to find out why a bunch of Oil is finding it's way into the Combustion Chamber's. And if I'm Lucky I'll stumble across what ever is causing the idle issue along the way.

Oh, sorry I thought I responded. I had checked it before I even Posted. I actually have it fully retracted. It's doing this with the Butterflies fully closed, which has me thinking some sort of Vacuum leak that's why I re-seated the Carb Boot's.
