bottom chain roller

CHAIN ROLLER YFZ 450 RAPTOR 700 YFM 700 YTZ 250 BL34mm - eBay (item 190480600408 end time Feb-13-11 11:16:01 PST)

i would'nt even use the stock one, i would go with these in the link. they have a little dust cover to help keep the dust out of the bearing. they are easy to install, all u need is a hacksaw to cut off the old tube that the stock roller sits on and then drill the hole out a little bigger to accomodate the new bolt in the kit and your done and you can thank me later. they make the cover in different colors too
