:wondering After stripping the phillips head screws holding the two small retaining tabs over the bearing in the left case of my '85 250R, I tried to drill and extract them. The initial reverse drilling took the heads off, but when I went with the smaller extractor trying to get the remaining piece out, all hell happened and I dug into the case. Is it toast? Do I need to look for another or can this be tapped to still use the retaining tabs? So pissed...

Shouldn't be a problem with a heli-coil or a timesert.

Never done that! I'd wanna find someone with experience to do it. Schematics from ServiceHonda doesn't give a size and pitch for those screws, either.

It helps A LOT, and I appreciate the tips. I've had automotive stuff helicoiled before, but it didn't cross my mind when I screwed this up. Gonna swing it by a shop this week. Thanks again.

A wise move that should have been your first choice. They don't make a lot of trike parts anymore, best do your learning on an old lawnmower engine before taking a hand drill to a 30 year old trike case. The good news is you didn't wreck it, but do take it to small engine machine shop to get it fixed.
