yeah , what joe said it makes a huge difference run the bit slow with some pressure , but make sure your center in the broken stud you dont want to accidently damage your threads , and drill down about 1/4" or a little more just enough so the extractor will dig in and bite. turning ccw should remove the broken stud! did you use any loctite upon first assembly on any of your studs?

I don't think you're gonna weld anything on a bike with that technique.

welding will not work,i have been welding 30 or more years  ing even with mig or tig your engine must be grounded ,a bearing will cause an ark between the balls and lead to bearing failure. pick up a screw and bolt removing kit at sears they work great.

In a pinch you can sharpen a right hand drill bit to cut turning left. Takes a little practice though | | Thread Tools | | | | Display Modes |  Linear Mode |
