Do a google search for 2002 Mastiff and look at all the pictures of 250 tires. Also do a search here for 2002 BD rocker covers/heads. At the end of 2001 the last ones made and 2002 on had a hole in the top of the rocker cover and a nut inside for the releases. If you got a 230 tire from the factory you got a special Dog. Check your rear fender for the 2001 tail light (one year only), 2002 on light was removed from fender, 2002 fender will not work with a 2001/230. I tried. Things were fast and loose in the company back then and I bet you got a bike off the line of the 2001 manufacture. It must drive you crazy looking for parts as there were lots of changes.
