The Motobrick Workshop / Rear rack from a K1100RS to a K75?

[although I'm intrigued by a groovy new tool!]

Ha ha, bought mine in my 30's (choice between a cheap car or a nice bike) rode the piss out of it for 35 years. It was the right choice.

I replace them with worm drive hose clamps and hide the worm drive part on the back.

It looks like a pliers (pull the tab taught) and punch (smash down the locking rectangle) operation, but I don't want to mangle brand new parts.

Happily, the difference was explained to me by an experienced BMW auto aficionado. Knowing the difference between the two can lend to observers the impression that a feck concerning the engine management system is given, regardless of whether it actually is given. You never get a second chance to make a first impression. 
Anyway, without the data provided by the air flow meter, performance of the Brick's 2V engine is usually fecked-and-a-half. Luckily for us owners, it is an unusually sturdy unit seldom needing service beyond ensuring that its air vane moves freely, its air temperature sensor is not coated with detritus and that its electrical connector is plugged into it to enable the sending of data to the LE Jetronic.
I strongly suggest that all owners of 2V Bricks not already having done so, read the LE Jetronic training manual—available in the Service Bulletins~Brochures section of this site—to understand how the engine works and to help them unravel messes like the one schrockteer is encountering.

One of my intake manifold to airbox boots (officially listed as a "bearing" at Max's) was blatantly cracked. I'll get those ordered and installed, and report back.
BTW, is there a special tool for the one-time steel clamps that go top and bottom of the airbox boots?
Thanks

« Last post by The Mighty Gryphon on April 17, 2024, 06:51:57 AM »+1 on Laitch's reply. The engine won't run with any of the air intake stuff disconnected. It'e impossible to get a proper fuel/air mixture without a sealed air intake system. There can't be any air leaks between the air flow meter and the cylinder head.
When you say "S air vent" do you mean the Z tube that connects the air box and the engine block vent? The Z tube is important to getting a good idle and proper throttle response coming off of idle.
I'm sorry, but the previous owner is a moron when it comes to fuel injected engines.

The Brick likely won't start or run well at all without accurate data coming from the air flow meter, and its temperature sensor, being input into the LE Jetronic fuel injection control unit for calculation of correct fuel mixture, but the meter in this Brick can't transmit doodely-squat to the LE Jetronic because the feckin throttle bodies are disconnected from the air box that is connected to the airflow meter, and that condition means that the fuel mixture computation is fecked from lack of sufficient air flow being drawn through the meter by the air pump that is otherwise known as The Engine.
The Service Bulletins~Brochures section contains the LE Jetronic training manual. Point #4 in the list on p.8 explains part of the situation. Necessary parts seem missing, decoupled or generally fecked, but Hope is eternal.
