erratic tickover after new gasket...help

Cheers Steve.
The reason why I ask is that I have my bike back from the dealers and it is purring ..fantastic...
I took the bike in the back of a van even tho' it was running, I took all the front body work off to save the mech doing it..
They looked at it and I received a phone call a couple of days later saying that I need some part"S"..I was told that the "t" piece was missing from the bottom of the air box...Is it on your garage floor?? and that I needed a new one...They could supply one for me for one hundred pounds...I will ring you back I said after I ring motorworks to get a second hand one for sixty pounds...
Five mins later he ring me back saying that the "t" piece is not missing now and that it is still there but there is a hole near that area that should have a tube coming from it, obviously you have broken it when you took the air box off and now its letting in extra air.. I told them to block it up with something and that's what they said they did...
So the air box "outputs" are as follows...

Electrical connection at the top of the box
Electrical connection at the r/h/s near the fuel rail
A t piece that connects to the two small tubes that go the the throttle bodies
2 outputs for the throttle body rubbers (main air intakes)
Valve cover breather tube
and now there is another one some where on the bottom of the airbox that I have never seen...

Anyhoo, Im one hundred and thirty five ponds lighter but the bike runs great....

They did connect it to the computer because my service light has gone off..
So I tip my hat to all that said air box leak...
When I picked up the bike today I asked the mech about water in the airbox and all he came up with is condensation because the water system is not connected to the air box....

So that's it guys, The bike is running great and I just need an mot and tax and I will see you on the road...Ride safe and thanks to everyone who helped ....Tosh
 
If this "T" piece is what I think it is, I've got the scottoiler vacum tube connected to it. Maybe they come blanked off from the factory! The "T" piece sits in between the two air bypass pipes that connect to the throttle bodies, connecting one to the other, to help balance the air in both.

Glad your bike is sorted and running well.

Popped the airbox off of mine earlier on, to put the original plugs back in. Airbox has plenty of condensed water from the crankcase breather in it again :eek: :confused:
Tomorrow I'm going to bodge a condensation trap onto the side of the bike and route the crankcase breather pipe into that and blank off it's connection to the airbox.
Then, snow permitting, I'll put some miles on the machine and see how much water has condensed in the bottle.
It is friggin cold up here just now, but I never had this problem last winter whilst running the bike back and forth to work!

Till tomorrow then.

:cool:
 
Well Im thinking of a small 4mm hole where the water collects, just a tiny little hole small enough not to make the bike run rough but big enough to let the water out..I would start with a tiny tiny hole and work up from there..
Or put a screw/bolt in the hole making its own thread, removing it once a week to let the water out.
 
The only hole oon the bottom of the aurbox, that I know of is visible if you remove the black cover above the rectifier.
I have my scottoiler connected to mine.
 
Im not being funny about this, I truly cannot visage a nipple or vacuum extraction point on any of the underside of the air box,,,anyone have a picture ???
 
johnyboy,
ive looked on youtube and I found the video of scotoiler installing their product on an 800 gs.

Ive looked at the underneath of my airbox and the small tube that the vacuum is attached to is missing..So I must have busted it off somehow...Ive looked online at various fiche and all of them are based on the 800gs...I cant find the part numbers for the 650 and the 800 airbox..Just to confirm that the 650 has the vacuum tube just like the 800..
 
Yep Item 22..
The only thing I can think of is that I busted the "tube" that the cap fits into when removing/replacing the airbox and pushing it onto the throttle body rubbers....
So that's it, the mystery has been solved.. Bmw Grimsby got it spot on.. Perfect diagnosis and perfect repair..
So once again I would like to thank everyone for their help.. You guys really did rally round for me...I hope one day I can do the same for you...
Thankyou...Tosh...
