Just a mention... You may consider getting the case Tig welded as it's pretty much a full strip down of the engine. It's a proper job done then

although I will agree with you on tig welding the case ?, but !. not everyone knows or has access to a tig welder next door ?, not to mention, it won't come cheap by any means !..lol. but yes, you are correct. heck, even some one that does aluminum welding will work very well. had this issue pop up on my buds trx500FPE cases, he had a guy do some aluminum welding to build up the oil drain area, worked pretty good. again, you are correct, tig welding is the way to go.

Very true, I'm lucky that my Dad has a Tig welded and that the UK is so small the nearest guy with one can't be more than 50 miles away!
Aluminium can also be gas welded(Oxy Acetylene) and Mig welded, that could be another option for the OP.
