I don’t think that’s what Indy was asking....of course you would split the cases and empty them out, no question, I think he wanted to know if you could do this procedure by hand (die grinder and carbide tip) or do you need to use a boring machine for the fly cut?
Cheers Pat. I have split and empty 36Y cases on my bench.
I can see no reason why a steady hand and paitence couldn't achieve the required result when it is the only practical option.
I'll make a few phone calls to some engineering shops, I might be surprised.
Motorbike engines are not their thing and they usually refuse to work on them.
Granted, this should be pretty risk free.
All previous work like this was a simple case posting it to the UK, not an option anymore due to duties and taxes charged on both legs of the journey.
It's a nightmare.
Some metric figures for the openings required would be great.
