i have a 93 warrior and my chain rollers are gone and i mean gone, nothing but the bolts left. will any of these universial rollers i see sold fit. what size will i need on the top and bottom. i have seen them in some of my atv catalogs but all they say is small and large. also anybody know of a web site where they sell big bore or stroker kits for warriors. i talked to a guy at a local shop that said he had a 436 kit in his warrior. it sounded realy healthy.
