Yes docc, your bike like many is breathing oil into the airbox and it ends up on the LHS because that's the side it leans on due to the LHS side stand. Ciao

The idle MV setting is a "guide only" not a specific requirement. It's only so you can set the idle screw to a start point after you've had the Butterflys fully closed to set the TPS and have a rough idle position to begin the tuning process. Ciao

He needs to remove the air filter and look INSIDE the airbox at the airbox floor, not just at the filter. Ciao

The port to nowhere is what it is. It just senses atmospheric. Used to sense intake port pressure in other applications in the early days on Ducati's for example. If its running rich as hell all of a sudden then about the only thing that can cause that is a stuck fuel pressure reg. I've not personally seen one fail but if you leave them to dry out they do tend to stick closed. You can hear the pump load up and suddenly there's a pop as it unsticks off it seat. I bought 2 phase sensors about 18 months ago for 10usd each from China. Seems to work fine and indistinguishable from factory model. If you look at aftermarket suppliers in the automotive world that sell thousands of these for cars which they have commonality they generally charge around $50 or so for them and I can guarantee they will be Chinese versions as well. I put the info on here at the time. Ciao

As I said too many digits for a part number. The position and qty aren't a constituent of the part number. Nor is the GU in the majority of parts systems including Guzzi dealer systems. Ciao

Too many numbers for a Guzzi part. Both models are 01114031. The frame was lengthened just behind the steering head so the airbox is unaffected. Ciao

The top transmission mount on both sides where the trans connects to the frame. Look at my V11/Daytona thread. I did a comprehensive repair in that thread with lots of images and explanations. Ciao

Well although you don't believe it's gearbox oil if you don't get a result with the simple stuff dont discount a cracked gearbox mount when you've exhausted all the other simple possibilities. Ciao

That CARC bleeder mod was a 30 year get to production affair Pete. Guzzi don't rush this stuff you know, got the be thorough in the R&D Ciao

Umm, haven't you answered your own question with the system operation returning to normal bleeding the slave bleeder after the master bleeder. Ciao

Wasn't there a black and silver version created by a US dealer and called something forgettable back in the day. Wasn't a "factory" release but a US local individualised and locally marketed thing. One dealer only Marketed I mean. Ciao

Yes and soon. Ciao

My Centauro engine had been contacting the sensor as well when I bought it. Don't know if it was affecting running but it deposits metal in the oil. Ciao

HMB Guzzi, Stein Dinse. Ciao

I wouldn't leave it with 0.002" clearance myself. Or is that 0.020". Ciao

This guy is impressive. Ciao

And you're still riding it! Ciao

Got to be happy with that. Ciao

I saw in the initial images the throttle plates looked a little too far open to me but I thought it may just be the perspective. My previous recommendation was to establish that the butterflies were completely closed and both sides were baseline synced together as a starting point. You can then at least start the engine and keep it running on the throttle without it running away until you can set the idle roughly. When you get the idle roughly correct on the idle screw the butterflies will be slightly away from fully closed on the TB bores, naturally. Then you can do a proper balance and tune. I now see the OP is asking about the white linkage knob and whether its the idle adjustment and know we are in a bit of trouble. As docc says, follow the decent tune-up thread. Ciao

I'd wind out the l/h TB idle screw until it has clearance ( the r/h should be clear already if one is indeed fitted) then disconnect the linkage and make sure both throttle plates are bottoming out inside the throttle bodies. You should adjust the linkage so when both throttle plates are bottomed in the bodies the small post on the end of the linkage aligns perfectly with the bush on the l/h linkage, then refit it. Wind the idle stop screw on the l/h side until it just touches the linkage and give it half a turn. This will guarantee the throttles are closing and then do a balance and idle adjustment. When you start it up it wont idle but you can adjust the idle stop screw until it does and you're in the ball park. Check the fast idle cam first. Ciao

Ok so you didn't remove the throttle bodies from the bike, just the engine? Ciao

How did you remove the throttle bodies, separate them from cross over supports and remove individually? Ciao

Have you checked the fast idle cam is clear of the throttle mechanism? Ciao

Probably a 3 part paint finish, base coat, translucent colour coat and top coat. If you strip them to bare metal, bead blast them and paint with dedicated engine enamel within 2 or 3 days you wont need to etch prime or prime them in any way. Ciao
