I've got a small leak in the oil seal around the kick start spindle on my xr6, I've already bought a new oil seal to replace it. I've heard that you can just (carefully) drill some holes in the old oil seal and pull it out with some needle pliers and push the new one on with a long socket (after cleaning it up) and you don't have to pull the crankcase cover off. Anyone ever tried this or have a better idea? Would also like to try this procudure on my dad's xl500 which has a BAD oil leak around the oil seal on the gear shift spindle. I've bought both oil seals and they both look smooth on the outer surface that makes contact with the covers (no grooves or anything). Thanks for any info.
