I know the feeling. Finally got mine all back together after however many months of screwing around with it, got the shifter setup and everything else working properly, successfully made my own throttle cable for the first time, got it running and driving, and was even starting to get the tune dialed in...and then, during a test ride a week ago, the rear brake cable just up and snapped. (I still had the front brake, thankfully.) It was at this point I decided to shelve it for a bit and take care of some other things.
