This is an old post so not sure if you have got your answer but you can order the updated kit from your locak AC dealer. Take the # into him as they have a tuff time looking it up.I have a 14’ X ltd, have never had any backfires or symptoms of this. But i am wary of it happening. Anybody know of a place in Canada I can get this new starter and gear? Awesome offroad doesnt ship here. I am in Vancouver, BC.
