The kill switch on my R is stiff. Not stiff as in dirty and gummy, but stiff as in the little cam or bump inside is too high and it's hard to compress the jesus spring to move over the resistance.
I'd like the switch to operate a little easier, but I'm not eager to try and disassemble without a bit more knowledge than I've got. Has anyone taken one of these things apart?
I do know the work-in-a-plastic-baggie technique, but a plastic baggie full of parts is not much better than disappeared parts if the switch can't be reassembled by human hands.
