1985 K100RS removal of air box lid.

Okay. I know I'm not the only one who has had this problem. I cannot get the lid up enough to slide the air filter out-I've tried and tried. There is a wiring harness between the frame and the lid and it just won't give. Not only do I want to check the filter, I also want to remove the air box unit to access the fuel pressure regulator to change the hose the goes to #4 throttle body. Really guys, I am at the end my rope. HELP!

It's a bear... I found that having more than one set of hands helps. I also remember that releasing the gas tank from the rear mounts allowed for just that much more give (but it's been a while since I've done it).


 
I'm very sure that you really have to loosen and pull back the gas tank to get the top of the air box out, at which point the bottom is easy.
 
The tank is off, guys. I'm in the process of reassembling after having done spline check including removal of clutch.
 
Find the wire ties that keeping the interfering bundle from slipping up beside the backbone. Remove them. Move it. Lift top. Extract filter.

Thank you. I've seen this but he's got more room above the lid to begin with than I do.

Thank you. I believe this is probably my best chance. The harness goes to a plastic box (not the ECU) just aft of the fuel tank that has relays in it. It passes through a large u-shaped grommet.
 
While bending, pushing and muscling all the crap out of the way so you can perform this simple maintenance job, keep repeating to yourself "it was designed by German engineers who excel at creating precision designs to exacting standards."

Got it! Stay positive as this was all done to my benefit not detriment.
 
Well, I finally got the air element out. I did see what the issue was with respect to the wiring harness being right on top of the lid but that wasn't the problem. The first picture shows the element before I completely removed it and you should be able to tell just by looking at the element why I had such a struggle. The second picture shows the element stood on the end that was in the back of the air box. Figured it out? And it was as a result of something that was done by the last moron :banghead who was in the air box.

Doh! That would sure make a job out of getting it back out. I'll bet the guy who did that was cussing BMW for making inserting the new filter so hard. :laugh
