I have posted in a few other areas and topic but figure starting a thread for the bike is appropriate.

"Katrina" was purchased inexpensively from an Atlanta company that buys trade ins at a Ducati dealership. Great price, nice guys, "it runs" was the good part.
I'll post links to my other few threads in a reply but for now here's what's done:
*
New battery Sealed battery seems like a wee bit too big. I may swap with the smaller one on my K75 RT
*
Two new keys that fit the ignition & tank but no fork or seat lock. Do *NOT* let a motorcycle dealer cut your expensive ($10+?) BMW blank keys. Proper locksmith is the way to go. Sandy Springs Locksmith on Hammond Dr. did mine. $5 to cut two blanks that I brought in. The dealer cut was *way* off
*
Changed oil but not filter. Bought a filter
*
Dropped float bowls. Cleaned them, floats look used but flipped and flopped.
*
Brake light works. After much cleaning of the rear terminals. "Katrina" may have seen water
*
Dash & gauges removed - Water line visible in gauges?! They're trashed!


*
Seat release lubed - Lock doesn't seem to work with this key? Lots of lube, no love.
*
Removed starter cover and airbox top. Filter a bit dirty, starter looks new.
*
Replaced fuel filter - I'm amazed at the clampless BMW fuel lines. I have read they're 7mm or something magic that makes them just "fit" without needing clamps. Where can I get the magic fuel line??
*
Fuel tank futzing - Flushed it a bit. It's on the borderline of servicable at this point. We have done a few rust removals with baking soda and a battery charger with good luck so may do that. The tank does seem a little more twisty inside than a UJM tank.
*
RUNNING MOTORCYCLE - The bike starts. Dumped fresh gas on top of what was left from trying to flush the tank. The exhaust leaks (front crossover, rear near foot peg) are noticeable. The front one can be made to pop FIRE!
To do:
*
New float bowl gaskets. I pinched one reinstalling the bowls and have a slight leek. While they were easy to get off with some tools should the snaps that hold the bonws on be a trivial "snap with fingers" deal?
*
Easy fluids of the transmission & final drive - 80/90 and some crush washers, eh? Anything else to do that's trivial?
*
Rework the exhaust. There's a hole in the front crossover on the left side. We had some shots of flame out of it. Is this timing or ?? I didn't know there were *TWO* crossovers but it looks like there are! What are the implications of removing both crossovers in terms of leaving the carbs alone. I think we're mostly curious about deleting the front one. Or would take shade tree advice on where to shop for "bits" for building or repairing one - what size are they? Clamps, elbows and some standard size rural exhaust pipe? Auto parts store? I think this system is salvageable. I'd rather spend the bucks on tires when I get there...
*
Lubricate cables and throttle/choke - Sort have been doing this. The choke still seems a bit firm. We did free up one of the choke pivots which seemed to help the bike start and run.
*
NOISE FROM STARTER SOMETIMES - The starter looks new. Given how effed the rest of the bike is electrically and how fresh the starter looks I would say it was replaced "recently". Is it possible the flywheel is stripped ?? It's like the starter runs sometime and isn't fully engaged. Sort of a puffing noise more than gears spinning free or going BANG BANG BANG. It's not a pleasant noise - sounds mechanically wrong.
* Lots of rust surface rust removal.
* Single brake line conversion. Anyone done this? My hard lines are ugly and I won't be putting the bike back together stock. I'm running single discs but thought I noticed the hard line lower part had 2 outlets and one was capped??
*
Wiring. Maybe dirt-GS bobbering it. What are these connectors for?:

Also any pinouts for the main circular dash wiring connector based on pin#s?
I have a spare relay spot and a few connector blocks under the tank with plugs in them. What are they for?
