Replacement controller for ze-2000

Just looking at the shoddy soldering job inside the controller
assembly, I should have expected failure after 2000 miles.

The bike died in the middle of my way home one
night. I took the controller apart to find an open
pathway on the far right burned open. I repaired this
today and the bike worked again but with intermittant
cuttout. Now it's back where I started. The bike turn on
lights,ticker, battery meter all work fine. Just no throttle.

Matt, you mentioned something about replacing yours
with a Kelly controller. How is this coming along for you?
I'd like to get a replacement that won't fail every 2000
miles.
