Help my Yamaha XS650's TCI unit is faulty?

Question

Any ideas as to whether it can be repaired or are there any substitute units from other bikes I could use? The model is a 81 us import heritage special. Or failing that do they still make new units?

Answer 1

try denniskirk.com they may have parts  for it. they made these bikes for many years and they all should fit.  

Answer 2

any unit off of a working yamaha XS twin will work, even from the junkyard, i have good luck from the local motorcycle grave yard
