Downpipe studs - Bit of advice

Don't snap them.

A couple of mine snapped from when I was doing my engine transplant and it's costing me in the region of £300 due to the Labour and having the head sent off to get the studs out.

The guy doing the work for me was planning on transplanting the head from my old engine, only to find the head wasn't in a good way.

Expensive lsson learnt - be careful.

Could you not have just drilled them out and re tapped the threads?

I didn't have to confidence to do it, the mechanic didn't want to risk it either because it's too easy to go wrong

Looking at the top of what's left of the studs, are they:

A - flush with the engine casing
B - Stand proud of the engine casing
C - In the recess of the threads

Answers (and preferably a picture) on a postcard to Stretchie Rusty Swingarm Grease Nipple care of this thread

  

Stretchie Rusty Swingarm Grease Nipple? Haha

One is flush with the engine casing and two are protruding about 10mm and completely stripped

I'd send a picture, if I had one, but the bikes with the mechanic till next week

I would guess the mechanic could weld a threaded rod or a bolt on to the studs then undo them, that should do it
