i put a iridium in my foreman and after about 20 seconds you could hear the idle drop like it was nothing, i cranked it up with old plug in to hear it then took old plug out and put new iridium plug in and cranked it but i immediatly walked away to go do something else and came back a few minutes later and i couldnt tell it was running till i got rite up to it, bike seems to all around ride smoother and run better IMHO...not sure what the number is for a rancher but for the foreman i think the number was like 5468 not sure though really i know someone knows the number for the foreman but not sure if its the same for a rancher

yea same here, i rarely had to use my choke ever with old plug, when i put iridium in the only time i have to use it is if it hasnt ran for a month or more but i usually go out once a week to let it run for a few minutes

either try 5468 or try 6468...it is around $7 bucks...i got mine at an advanced auto, they had to go in the back and get it, just ask the guy to look it up on the computer...the number u give him to punch in will send him to the correct NGK number which is like 2 letters then the 4 numbers

thats all i got, i think soemone in the 500 forums has the number in there signature just gotta find it
