Default V92C Diaphragm missing a hose....

I have had alot of time messing with my bike and doing maintenance... I ran across a diaphragm on the left side of the throttlebody with fuel inputs on the bottom and a open connection on the top... Something tells me it should be hooked to something... You can see it just to the left of the TB (I cleaned it)...

What year is your bike? I'll try to get a look at mine tomorrow and see if it has that

2000, Id appreciate any help! Something tells me it is probably the cause of my overly rich idle and afterfire when I let off the throttle between gear changes.

I can't tell you exactly what purpose it serves on the fuel rail but nothing connects to it.

I can't see anything like that on my bike. I would try to get a service manual for your bike and see if it has anything about that in it

I have the factory victory service manual.. Probably the least useful service manual I have ever purchased. Nothing in the manual about it.

You could maybe try putting a cap over that port and see what happens. I have no idea what that could be

I think it is some form of vaccum compensator for the fuel pressure. But there are a few different vaccum sources and it may need to be metered. I have seen the diaphragm with the TB for sale on a bunch of fleabay auctions, so it is original.. Im at a loss.. If it wasnt such a pain in the ass and risky (fuel tee) to remove the tank id just try a fee different setups..
