Solved.

I used the propane test to identify that one of by intake tubes under the butterfly assembly had gone bad, item number 3 in the diagram.



As for the propane testing that I did i found the info on how to do that from a thread called k1100 intake rehab

Heres the link
http://www.motobrick.com/index.php/topic,624.msg1572.html#msg1572

Again the book I have refers to the piece in the intake manifold as a tube not bushing. Though thank you for the help.
lol, yeah, like I said, the third one leaks.

Okay my apologies to the forum. I have zero patience for public shaming or condescension.

you may need to find a different forum then. I have found this forum essential to a properly running brick and the inmates on this site have been more then helpful, however the price of admission often seems to be a varying amount of humor and attempted humor, a small price to pay for all the great help.

And not everybody can get the grips with my British sense of humour. Sarcasm is a major part of it, it depends if you can understand it. We call it ‘banter’...

Thin line on the humor bit, but to each their own. Either way I feel bad about causing the ruckus.

Is there a way to get your throttle plenum off without dropping the engine out? My book says lift but ive got the frame right there.

It can be tricky, but it squeezes right out. I found it easier to remove the tank, although, at a slightly later date, when I changed the fuel lines, I put slightly longer lines back on, only about a inch or so longer, so that any ‘under tank’ work can be done without having to disconnect it. Just move it back, then lift to the left, and support it with a ‘bungy’ cord. When replacing it, silicone around each inlet rubber, then replace at a slight tilt towards you,then push in and down till upright. There’s a bit of a knack to it.
