It is Alive!
Got the BW200 running by midnight.
I wanted to see if it would still run before I tear it apart although I knew it is stuck in 1st gear. The carb is garbage, it runs and idles but I had to free the slide and there is so much corrosion I worried about breaking the float mounts off while cleaning it. Just lucky it would run.
Going to clean the whole bike up tomorrow in preperation for the tear down later.
