Ok so I'm pretty new to the forum but I was working on my blaster the other day and noticed the seal for the shifter shaft on the case was leaking. They say ur suppose to take the case off to remove it but I wasn't trying to do all that so basically u just prop the bike up half on its side to make working easier clean around the seal so when it's removed no dirt gets in take a self tapping screw and screw it into the seal be carefull not to hit the case cause u will put a gouge in it now after the screw is in u can clam a vice grip on there or a slide hammer and yank it out. Put grease around the outside and a little on the inside were it slides over the shifter shaft use a flat punch and evenly tap around it till its seated in. U also must remove the shifter lol mark it with white out before u take it off makes it easy to put back on in the same place. Hope this helps sry I don't have pics pretty easy tho
