Kill switch shocking me, also dying at idle need some help here

[250r rider 88]

I used to have a pro design kill swith on my R then one day it shocked me and it never ran again so i replaced it with a new pro armor now it runs but does the same thing any ideas its when i touch the metal part

also when im not in the throttle it dies like at idle i just had this thing tuned not that long ago and it would idle and never die on me any ideas

You have the wires on your kill switch reversed. Switch them around, and you'll fix that problem. For the idle problem, try turning up your idle screw on the carb.
