So, if I twist the grip to accelerate, the throttle will not return on its own. I opened the "Pit of Doom" (tm) last night and there's plenty of grease, both cables are fully connect to the grip. My next guess is the springs attached to the carb, unless there's an adjustment to be made somewhere?

Has the throttle lock screw -on the bottom of the lever perch assembly- become over tightened?

Never even noticed such a thing. The next time I'm in the garage I'll have a look.

What year bike do you have ?

At least it sounds like he has a 79-80 with the dual throttle cables, and not the splitter/junction gizmo that was on the 81-84 bikes.
My throttle on the R100/7 was very slow to respond - it had grease in it, but also alot of old grease and the inside of the throttle tube/outside of the handlebar was coated in some gummy substance that may have once been grease. I took it all apart, cleaned it and regreased the chain/cam/gear assembly and put some white lithium grease on the cleaned handlebar and re-installed - works much better now!

Matt,
As a long-shot suggestion...make sure the lip of your rubber hand grip is not contacting or rubbing on the handlebar perch during operation.
You may want to disconnect the cables from the handlebar gear and eliminate the throttle mechanism portion to make sure the cable(s) are operating properly on their own.
Just guessing.

It's an '86, so dual cables on the gear dingus.. It was pretty easy to put back together, now that I think about it, meaning that the cables weren't retracting very well even disconnected. It has gotten a little bit stiffer recently too, so I suspect Monte collects another beer. I even went to max bmw fiche site to look for the adjuster, and it seems like there should be one. Not too surprising that I didn't know about it, I don't look at the bottom of the handlebars that often..
