I bought a used 2003 Kodiak 400 a few months back and while trying to find out more about this machine I have found that there are different suffixes following the YFM 400 model number. Can anyone tell me how to find out what they represent. I assume that they refer to different "options" available. The reason I ask is that I am having trouble finding front rims that don't rub the brake caliper. I am accumlating a collection of front rims that don't fit, although I have several different decent tires out of the deal. I appreciate any help and thank you in advance.....
