2006 Questions for all other cars 3000 miles

This is a general question regarding bolt extraction-I have a Buell Blast that needs to have 4 bolts extracted after 4 (all four) were sheered off-They are in the crankcase, and the manual specifies that they can't be tapped out-

Now, I know the mechanics of bolt extraction and have done it before, but never when so much is riding on me doing four in a row, with no failures.

As it is, I am going to have to do the drilling for the extractor(s) with a right-angle drill because the space is so tight.

Any tips from those who would jump head first with confidence into this challenge? Please. Give me some confidence and insider tips! I'd hate to have to shitcan a crankcase because I'm such a novice!

Oh-The old bolt pieces I have to get out were torqued at factory to 30-35 ft lbs, and yes, lock-tite was used.

Having had a harley for the past 30 years I kinda know what you are talking about. You would need a 1/8 drill to start and go larger. Then when you are ready to get it out you would need to heat it. Nfortunately the cases are aluminum an dhte screws are steel. Not a good thing. What i'd do is check a machine shop out that has electric welder type thing that can remove screws. I think it's a screw extractor, anyhow a machine shpe would know what it is. They can burn the bolt on both sides and it will fall out. It may be easier to just pull the motor and take it to them.
