...and for the chain rubbing the tire. My tire hit my chain when I put my wheels on my YZ250F (160 tire on 4.25" rim). I put my bike on a stand with it running in 5th gear (had my bro hold the bike) I got a cinderblock and put in on the ground next to the tire and pushed the block into the side of the tire that was rubbing on the chain. It took only a couple minutes (and a little bit of smoke) to wear the side of the tire down to clear the chain. It worked perfect with no special tools and the tire is perfectly 'cropped'. The side I cut down is the same side I ride circles on and I have no problems. If you attempt this I would watch the bike to make sure it doesnt over heat. May want to get a 3rd person to hold a leaf blower in front of the rads.

or let it cool off in cycles till its good. I did it by myself with the idle turned up and it took me less than 5 minutes.........
