yeah ive put a switch on mine and mounted it on the bars, so that i can switch to yz or wr mapping easily. although if you do have it like that, you sholuld only switch when the bike is off. i think it can wreck the cdi a bit.

i was thinkin bout d/cthe tps too, let me know how you go.

Is the Canadian model the only wrs that came w/o the throttle stop, hence no grey mod required?
I would have thought Australian model would be the same as the Canadian....after all both countries got the RZee500 :thumbsup:

Had a look at the grey wire and it was never connected from the factory!,it is there,just it has a blanking plug fitted to one end of the connector block,toolie is spot on,no throttle stop from the factory means the grey wire mod does not need to be done! :thumbsup:

about the blanking plug, mine had that as well, just make sure that that connecter isnt joining both wires to ground.

what kind of switch did you use? i picked up a little one from radio shack its rated at 6a @125vac , 3a @250vac, will that work?

yeah that should work fine, i dont think the CDI would draw to much of a current, (not sure) but still that switch has a pretty high amp rating. i used a SPST for mine, (single pole, single throw) basically just a simple ON/OFF switch. just make sure you cover up all your soldering joining with tape or liquid electrical tape, to make sure its not shorting anywhere. :thumbsup:
