Changing 3 holes

well changed the engine oil, gear box, and when I tried to chance and inspect the primary.....I stripped 3 of the torex screws. Have drilled out bolts and screws in yrs. what's the best way?

Sounds like you stripped the heads, not the threads. Drill out or grind the bolt heads down so you can remove the primary. There should be enough left to get some vise grips on the ends of those bolts and back them out.
Maybe you were using the wrong size torx bit or it was not the best quality.

I went through this also. I (a buddy) was able to get 1 out using an extraction kit (https://frontporch.club/galleries/br...craftsman.html) and then the other two were reversed out using a chisel and hammer. Good luck.

I've had this happen on old neglected Sportsters. Drilled the heads off with a 1/4" drill bit, removed the derby cover and grab whats left with vise grips, they come out pretty easy when there is no tension on them.
