Hey fellas, need an opinion. Have a 91 Zuki lt250r and discovered a crack where the crank sits in the cases causing a bad air leak. I obviously must've bought this way but po masked it long enough with gasket sealer to run decent till I at least got it home. Reason I say it was like this is because it looks like a bottom end crankshaft bearing failed and scraped the whole inside of the cases where the crank sits. I guess that one way to trench the cases lol! But seriously it was obviously like that cause there aren't any marks on the existing connecting rod from hitting the case and the bottom bearing is fine on this crank. So I guess my question is what would you guys do? Do u think it could be epoxied or should I get it welded? Already talked to mr oconnor and he said he can do it. The other issue I found is the opposite case half has a crank bearing that is spinning in the case so I have to address that also and wasn't sure if I can fix that with green loctites or not. Anyways any input would be much appreciated. I'll try to add a pic too. Thanks guys. I've looked for a used set of cases but can't seem to find any that aren't worse than what I have.
