what year pro x is it?

they had different swtiches for the ignition timing and for the exaust valve timing. depending on the year. my brother has that setup on his 800 prox.

i believe it is for 93 or 103 octane… they like there go juice. some models also came with a switch on the bars just for the timing on a holeshot. to get the pipe hot.
