Caliper doesn't have any fluid in it yet because it failed to work after rebuild when I put fluid in it...bug number 1 that I need to sort out.

Some other bugs (maybe you guys can throw in suggestions)
-The boyer ignition doesn't like to cut off when the key switch is turned off on some pre-79' models (mine) so the solution was to remove either the red wire to the positive lead on the battery or the red wire on the positive leave on the coil. Removing either of these renders the ignition unit dead...a catch 22. So I need to devise a kill switch or ask the Boyer guys a better solution (I do not want a kill switch.)
-Master cylinder is not getting fluid at all through it. It's not pumping down the line and not gravity bleeding. I need to just pull the unit entirely and work with it off the bike. Suggestions on what to look for would be lovely.
-Clutch lever sensor isn't working. I probably just have the wiring backwards or the sensor itself is dead.

That's literally all the bugs I've had from this...not bad, eh? I'm sure I'll find more after riding it a while and after break in.
Things that still need replacement:
-My shotty /7 seat
-The blown, crusty rear shocks (buying ohlins)
-The crusty starter (going with the motorad toyota one)
-Air house covers (they're from 2 different bikes and someone hand drilled them)
-A few rubber bits here and there to make it perfect.

This coming weekends work:
-Time the ignition to full advance
-Sync carbs
-Factory torque all bolts
-Clean out and fill the drive shaft with fluid
-Run it at 3500rpm for a while to break in the engine
-Ride it 136 miles back to Atlanta :)

This about wraps it up gentlemen! Been the most fun and rewarding thing I've done. I blew my budget big time and I'm not the least bit upset about it, this is my dream bike and I'd do anything to get it where I want it. I love this bike and building it only made me love it more! There will be a few ride reports, videos and pictures as I add the last few bits later in fall but for now...it's almost done!
Thank you all for the input and definitely speak up more about potential issues you see!

See ya'll at Barber Vintage Weekend! (I'll be on the r90)

It isn't cheap. I'm still considering someone rebuilding mine, but having something that pulls less off the battery and weighs less is more appealing to me:

So here were the pics before I rode it yesterday. The fairing and side panels aren't on. Also, the old /7 seat is on ... bleh





Yay crooked bracket! (I'll fix later)

The steering isn't turned straight and the angle of the picture, more than likely.

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

I particularly liked how once started, it nonchalantly tilted it's headlight to the camera in a little "hello boys" pose!

Magura "europa" bars ordered from Bob's BMW.
I'm looking for something with about an inch more rise or less of a dip down. The stock S bars would be great.

I believe the red wire should go to the + on the coils. The + on the coils comes on when the ignition is on and turns off when the ignition is off. the - side is the "spark trigger"

That's how it is set up currently. There is also another red wire that goes to the positive lead on the batter and has an in-line fuse. If I pull the lead to the batter, I get no power even if the ignition is on. If I pull the other wire going to the coils, same thing. If I leave both on, I get continuous power, when the ignition is off even.
I need to fiddle with it more this weekend to try more possibilities.

Ya know, something about (our) '74 alloy signals..

When I see a nice BMW like yours, I start mentally drooling, then I remember I've got one (er, a few), too!



Although a little dirtier.
