V11 LeMans fast idle cable

[Sporticus]

Hello all,

I’ve owned my V11 LeMans for eight years and the fast idle lever stopped working a long time ago. I recently thought that it’s about time I did something about it.

Without first removing the tank, I can’t find where the fast idle cable attaches to the left injector or the linkage between the two. I’m assuming it attaches somewhere there. Does anyone have info or a photo or drawing showing the engine side termination of this cable? Thanks!

It's on the right side, very visible under the injector. No need to remove the tank.

Cheers Tom.

If you are going to do home maintenance (and who doesn't) the first thing you need to do is down load the parts and shop manuals, they are free and the answer to your questions are there. As for removing the tank. In a perfect world no but in the Guzzi v11 Sport world probably.

Between the cable attachment and the adjustable contact cam, the high idle mechanism on the bottom of the right throttle body has a lot of adjustability . . .

Have a friend move the fast idle "lever" at the bars and YOU watch what goes on at the r.h. throttle body . Look at all these linkages and see what needs to be done . 

 There is nothing under the fuel tank for you to see or have any affect on the fast idle mechanism .

Except a broken cable.

For instance, from here.

no doubt not entirely in accordance with various copyright laws, but it is all there. Navigaiting the site takes a bit of getting used to, but it is not that hard as to be impossible.

I've often wondered about that but I think it's an American freedom of speech/information thing isn't it? Not the same as the draconian EU laws on just about everything you can think of.

I appreciate all the responses. Thank you. Unfortunately, mine is not at all visible on the right side. Time to do some exploratory surgery.

If you look at the picture posted up above earlier in this thread the fast idle cable and it mechanical linkage can be seen just to the left of where it says "Throttle Linkage". Not where the arrow is point, but just to the left of those words. To see it you want to be looking up from below on the right side. You can see the cable, and the cable is connected to the plate that when it is pulled on by the cable it makes contact with the throttle and slightly opens it. The throttle cables attaches to the left side throttlebody, the fast idle cable attaches to the underside of the right side throttlebody.

It is a purely mechanical set up, you pull the fast idle lever, the cable connected to it pulls on a plate that as it is rotated by the cable it slightly opens the throttle butterfly. Since both throttle butterflies are connected by a linkage, opening one opens both. If the cable has lost its adjustment, if it has too much slack in it, the limited amount of travel that the fast idle lever has might not be enough to make the plate push the throttle open that slight amount that is required. You can see in that picture that there is a bolt that tightens down on the cable, you need enough slack so it does not open the throttle when you turn the handlebars from side to side but you don't want too much slack in the cable or it won't open the throttle when you pull the fast idle lever. Also, there is a known issue where a number of V11s, if not all of them, came from the factory with what appeared to be the fast idle spring and the seat release springs swapped. The springs have different stiffness's, and if they are swapped it can be, as I recall, hard to open the seat latch. But I might have that backwards. It has been a long time.

That's a great description of the mechanism. Thanks for clarifying the image, @GuzziMoto.

And, yes, way back in our V11 lore, there is the idea that swapping the seat latch and high idle springs makes the seat easier to remove and high idle lever stay in place better.

Oh. Maybe went bungee jumping? There is sound advice to swap the springs from the seat release under the tailpiece with the fast idle spring. The seat release can use more pressure and the fast idle, less.
